Reasons for a Honeywell Thermostat Connection Failure

Below, I’ve listed 10 of the most common reasons for a connection failure. I’ve also provided solutions and tips to prevent these issues from popping up in the future. 

1. Thermostat Not in Router Range

As I mentioned, the most probable reason why your Honeywell thermostat is suffering from connection failures is that it’s located outside your router's signal range.

So even if it may seem like a simple oversight, many people overlook this detail, especially since you can’t gauge the signal strength of the thermostat using your smartphone without advanced apps.

To determine whether this is an issue, check the distance between the router and the thermostat.

If the thermostat is situated at the edge of your router's signal range, it might be susceptible to connectivity issues due to minor disruptions, such as people passing by or interference from other smart devices and microwaves.

When attempting to connect the thermostat to your smartphone, verify that both the app and your device's software are up to date, and hold the phone closer to the thermostat for optimal connection.

2. Thermostat Can’t Detect Wi-Fi Network

In other cases, the smart thermostat might not be able to detect your Wi-Fi network entirely.

To resolve this, first, ensure that your router is switched on. If you've recently returned from vacation and forgot to plug it back in, this will be a quick fix.

Check for the 2.4GHz Band

Soft-Restart the Thermostat

If these steps don't help, try restarting your thermostat by disconnecting it from the main power or removing one of its batteries.

This action could improve the connection, especially if the network details remain the same.

Check for VPNs

Also, ensure that you disable any VPNs or spoofers, or force close their respective applications, before attempting the connection again.

3. Wi-Fi SSID hidden

Another reason could be that the Wi-Fi name is hidden from the public and other devices. Maybe you’re using additional firewalls or a computer-computer network. Either way, you can break down these digital walls with a simple solution.

All you need to do is change your router’s settings. To do that, access your router’s settings page. You can also do that from your network connection settings if your computer is connected to the Wi-Fi network. 

Another way to deal with this issue is by manually inputting the Wi-Fi name in your thermostat. You should be given an “Other” option when it comes to Wi-Fi names. Input the name of your network manually. Be careful about cases and spellings. 

4. Wi-Fi Disabled On Your Thermostat

Recent models, such as the T10 Pro, have the option to disable Wi-Fi connections. 

To enable it:

5. Wi-Fi Can't Connect to the Internet

If your Wi-Fi router is unable to connect to the internet, there might be a problem with your network or ISP.

Use Mobile Hotspot

If your Wi-Fi network is experiencing difficulties, consider using your phone's mobile hotspot as an alternative to connect your thermostat.

If that works and you can access the internet via your Wi-Fi, the issue might be in your Wi-Fi router. Therefore, it's essential to verify your thermostat's IP address.

6. Wi-Fi details have changed

Do you remember making any changes to your Wi-Fi network details recently? Perhaps you changed the name or password of the network. In that case, the thermostat will not be able to recognize the new network properties.

To solve this problem, all you have to do is reconnect to the network the same way you did when you connected for the first time. Find the network, input the password, and pair the devices. 

Try Disconnecting and Reconnecting to Your Wi-Fi Network

If you need to disconnect your thermostat from your home Wi-Fi, follow these steps:

After that, you can follow the app's instructions to reconnect your device.

7. Network Interference

A crowded network is tough on your router, especially when it lacks sufficient bandwidth to handle all of your connected smart devices.

Remember, the majority of these devices rely on the 2.4GHz band, and crowding can bog down the signal.

You must also be cautious about other wireless connectivity sources that might interfere with your Wi-Fi network; this includes Bluetooth devices and even microwave ovens.

To pinpoint the issue, prioritize your network needs by disconnecting or turning off other devices before trying to connect the thermostat again.

A less congested network should enhance the connectivity process for your thermostat.

8. Router needs a Reboot

A less common cause of thermostats disconnecting from the Wi-Fi lies in the router itself. Perhaps your router needs a reboot! Think about it, has there been a power surge in your house recently?

Maybe the router has undergone an automatic update? Could it be that some firmware bug took place? If you can say yes to any of these possibilities, it might be time to reboot your router!

The easiest way to reboot your router is by turning the power off and on again. If it doesn’t work, press and hold the reboot button for a long time to factory reset the router. That will also erase the Wi-Fi name and password that you’ve set up, which might be annoying to change. 

9. Issues with the Thermostat Specifications

First-timers setting up a thermostat connection can be tricky, so ensure you're aware of your network's specifications, such as IP address assignment, wireless security compatibility, and network types.

To find this information, you can check the box or user manual to verify that it matches your network.

10. Issues with Firmware updates

Firmware updates are essential for Honeywell Thermostats to function efficiently and maintain a reliable connection with your Wi-Fi network.

While updates typically occur over Wi-Fi without major problems, there are occasions where issues may arise.

To resolve connection failures, you should first verify if any updates are available within the Honeywell app or consider performing a factory reset on your smart thermostat.

Ensure that your Wi-Fi network operates on the 2.4GHz band, provides a strong signal for your thermostat, and maintains stable internet access throughout the process.

What is Honeywell Thermostat EM Heat?

Emergency heat (often referred to as “EM heat” or “auxiliary heat”) is a backup heating option available in HVAC systems that typically rely on a heat pump as a primary heating source.

How to Switch Between Emergency Heat Mode and Other Modes

Depending on the model, the option to toggle the emergency heat may vary. So to address this, I’ve created a model-specific guide below. 

You can check these guides or head over to our collated list of Honeywell thermostat user manuals to browse the guide for your specific model.  

Honeywell Home App

Here's how to switch to emergency heat mode using the Honeywell Home App.

T10 Pro and T9 Models

Similar Questions

When Should I Switch to EM Heat?

Setting the EM Heat on your Honeywell thermostat correctly can significantly improve your home's heating efficiency during cold snaps. Switch to EM Heat when your primary heat pump fails or cannot provide enough warmth. This usually happens during extremely cold weather (less than 30 degrees fahrenheit) or due to a damaged heat pump.

As such, it’s best reserved for true emergencies such as when the heat pump is damaged or nonresponsive.

In certain models, the thermostat will automatically make the switch. 

What Do I Need to Enable the EM Heat Function?

To enable the EM Heat function, your thermostat must be configured for a heat pump with backup heat. 

An installer will usually know how to make this configuration but you can also do this yourself in certain models with the help of the installation manual.

Also, the auxiliary heat pump's signal wire must be connected to the thermostat's wiring.

Doesn't Auto Mode Switch Over to EM Heat When Necessary?

Some thermostat models with the Auto Changeover feature can automatically switch to EM Heat when necessary. 

However, you still need to have the auxiliary heat sources (such as a gas furnace or heat strip) set up and wired correctly.

Is The Emergency Heat Setting More Expensive to Run?

Yes, emergency heat can be considerably more expensive than using the primary heat pump.

The cost difference depends on the heat source (such as gas furnaces or electric heat strips) and the duration of use.

Since it's pricier, I recommend you use the emergency heat setting sparingly and reach out to a professional technician to restore the regular heat pump functions as soon as possible.

The post Ultimate Guide to Honeywell Thermostat EM Heat Settings: 2023 Edition appeared first on Smart Home Perfected.

Normally these messages only flash for five minutes and then turn solid to indicate the system has started. However, if it keeps flashing, it could be due to a communication issue with the AC system. Air conditioning plays a crucial role in maintaining a comfortable indoor environment. Make sure to follow my troubleshooting steps below to get to the root of the problem.

What Does the “Cool On” or “Heat On” Indicator Mean?

During normal operation, the “Cool On” or “Heat On” message stays lit depending on the temperature mode. So if the air conditioner is working to cool down the house, the thermostat will say “Cool On.” It is important to set the thermostat to ‘cool mode' to ensure proper cooling. Meanwhile, if the heat pump is working to heat up, the thermostat will instead display “Heat On.”

“Cool On” indicator on a Honeywell T6 display

Compressor Protection Feature

However, if either of these messages are flashing it can imply that the thermostat is running the compressor protection feature, known as the delay mode. The delay mode helps protect the compressor by preventing wear and potential damage.

In some models, this message is displayed as “Waiting for equipment”. The thermostat activates a startup delay to protect the compressor from voltage fluctuations after a power loss, allowing the AC system to reset and readjust to normal operating conditions.

As the name suggests, it’s an intentional safety feature to prevent any harm to your compressor, especially in the event of a power outage.

By taking about 5 minutes to cycle, the thermostat ensures that everything runs smoothly and avoids the damage caused by intermittent power cuts or surges.

So after you’ve just recovered from a power cut, the “Cool On” or “Heat On” message would stay flashing for five minutes. After which, it will remain solid and the HVAC system will kick in.

10 Steps to Troubleshoot a Honeywell Thermostat Flashing Cool On or Heat On Indicator

When the “Cool On” or “Heat On” indicator continues to flash for more than five minutes without hot/cold air coming in, it can indicate a malfunctioning thermostat. If the issue persists, it is important to consult an HVAC professional to diagnose and resolve the problem.

If so, I recommend following the troubleshooting steps laid out below.

1. Wait 5-10 minutes

Your thermostat could be facing a slight delay in restarting and activating its compressor protection feature, which is often indicated on the thermostat display.

Make sure to wait at least 5 minutes before further troubleshooting. I recommend waiting for a solid 10 minutes so you can confidently rule out the compressor protection feature.

2. Set the Thermostat to its Lowest Temperature Setting

You can verify the thermostat’s ability to manage the cooling system by adjusting its settings.

• First, set the thermostat to the lowest possible temperature.
• Ensure that the mode is set to “Cool” and that the fan setting is on “Auto.”
• After making these adjustments, give it some time.
• Check if the AC comes to life or if you experience any change in the room’s temperature, specifically if cool air is being emitted from the vents.

This will help determine if the thermostat is effectively controlling the temperature function.

3: Check if the Thermostat is in Setup Mode or if the Clock is Set

In certain models, when the thermostat is recovering from a power outage, it may revert to setup mode, causing the “Honeywell thermostat cool on” lights to blink.

To resolve this, check your thermostat’s settings and make any necessary adjustments.

Also, verify that the time displayed on your thermostat is accurate. An incorrect time setting can interfere with the schedule settings and glitch out the thermostat.

4: Check the Thermostat Batteries/Power Connection

Weak batteries can prevent your thermostat from initiating the cooling process.

To fix this, replace the thermostat batteries by removing the thermostat from the wall mount and replacing the batteries on the back of the panel.

If your thermostat uses a 24 VAC power source instead of batteries, inspect the wiring.

To do so:

• First, turn off the power to your HVAC system.
• Next, remove the thermostat, ensuring you unscrew it first if necessary.
• Then, examine the C-wire to confirm its proper connection.
• Make sure there is no dust, dirt, or debris, and clean the contacts.
• You can also try reconnecting the terminals, making sure they are secure.
• Additionally, check the circuit breaker to ensure it hasn't tripped, as this can affect the power supply to your thermostat.

5. Check the Voltage at the Thermostat Contacts

If you know how to troubleshoot electrical components and you already have a multimeter, you can check the voltage in the thermostat wires. 

Make sure that the R and C contacts have a voltage between 24-30V; lower values might indicate insufficient power.

6. Check the Power in Each Component of the Cooling System

If the previous steps haven’t resolved the issue, you’ll need to diagnose the rest of the HVAC system.

• First, inspect the power supply of your air handler, fans, furnace, AC unit, and outdoor unit.
• Watch out for unusual humming or clicking noises coming from your equipment, as these might indicate a problem.
• Also, examine the power supply for each device.
• Make sure that connectors and sockets are appropriately plugged in, and switches are turned on.
• While examining your equipment, check if the doors or panels are properly closed. Loose or detached parts and any obstructions may cause the safety switches to disconnect, especially the furnace door.
• If possible, check the fuses or switches visually or by using the continuity setting on a multimeter
• Then, inspect your circuit breakers for any irregularities.
• Try turning your equipment on and off, as well as resetting the breaker corresponding to these devices.

7. Check the Indoor AC Air Filters

It’s essential to regularly inspect your indoor AC air filter to make sure it doesn’t need replacing. Replacing air filters every three months is crucial for maintaining optimal performance.

A clogged or dirty filter hinders proper airflow and can lead to decreased cooling efficiency and poor air quality inside your house.

It can also put extra strain on your thermostat and other equipment, ultimately leading to higher energy bills.

So I recommend making it a habit to change your AC filter every three months or as recommended by the manufacturer.

8. Check AC Coils and See if they are Dirty

The external AC coils can also become dirty or blocked over time.

• As the coil accumulates dirt, it hampers proper airflow and reduces its ability to absorb heat and adequately cool the air.
• Inspect your AC unit's coils to see if there is buildup on the fins, indicating the need for a thorough cleaning.
• However, always make sure the unit is turned off before attempting any cleaning or maintenance.
• To reduce the chances of clogging and improve efficiency, keep the area around the AC clean and provide ample space for airflow by removing any nearby plants or debris.

9. Reset your Thermostat

In some cases, resetting your thermostat to factory defaults might be necessary.

Keep in mind that this process will erase your settings and programmed schedule, so it's a good idea to take note of any configurations you don't want to forget.To reset a Honeywell thermostat, check out my detailed reset guide which covers all Honeywell thermostat models.

10. Bypass the Thermostat

If you’re somewhat more skilled at DIY, especially when it comes to dealing with electrical components, you can try to bypass the thermostat. 

However, make sure you have a multimeter and a proper tool to create a jumper wire.

• First, turn off the power switch on the furnace or air handler, and also disconnect the thermostat from the breaker.
• Then, take out the thermostat from the wall mount.
• After that, run one end of a jumper to R (Power) and the other end to Y (Cooling) or W (Heating) on the thermostat contacts.
• With this setup in place, turn the power back on and check if the AC or furnace/air handler turns on. 
• If these components turn on without any issue, the thermostat is indeed defective.

Final Step: Call in the Professionals!

When you’ve exhausted all possible solutions and your thermostat is still flashing “Cool On,” it’s time to get the help of an HVAC technician.

• A trained technician can likely pinpoint the problem and fix it with ease.
• Some common issues that may require professional intervention include damaged wiring, a malfunctioning capacitor, an obstructed sensor, or a blown fuse.
• In addition, components like the compressor, condenser, or fan motor may need further inspection.
• For a recently installed thermostat, an expert can verify proper wire connections and ensure the device is set up correctly for your specific HVAC system.

Conclusion

If the Cool On or Heat On message is flashing for more than five minutes, it will require you to troubleshoot the entire HVAC and air conditioning system.

The troubleshooting guide above will help you do just that so if you follow those steps, you’ll be able to get to the root cause in no time.

However, if you aren’t able to check the circuit breakers or the rest of your HVAC system, always get a professional to help you.

The post 10 Steps to Fix When Honeywell Thermostat Flashing Cool On or Heat On appeared first on Smart Home Perfected.

Troubleshooting Procedure

I’ve broken this guide into two sections for easier explanation:

• Scenario 1: If your thermostat has a blank display and is not responding to any button presses, then continue reading.

• Scenario 2: If your thermostat has an active display that responds to touch, but, the heating or AC unit is not turning on or reaching the set temperature then jump to Scenario 2. In this case, the thermostat may possibly flash an error code or message like “cool on”, “heat on”, “wait”, “waiting for equipment”, or specific thermostat error codes. This could indicate an issue with the cooling system, requiring you to check the thermostat settings, wiring, power source, and overall equipment functionality. Additionally, performing a thermostat reset might be a necessary step in the troubleshooting process.

Scenario 1: Troubleshooting a Blank Screen on the Thermostat

If the thermostat display is not waking up to button presses or touch gestures for smart thermostats, it may be a malfunction, an electrical problem, a blank screen, or the device may be out of power.

Besides that, it can also indicate an issue within the internals of the thermostat. A malfunctioning furnace door switch can prevent the thermostat from working properly.

So let’s walk through the troubleshooting steps in a blank display, step by step.

So let’s walk through troubleshooting a blank display, step by step.

Step 1. Check if the Thermostat Panel is Pressed In

First, you want to check if the thermostat panel is firmly pressed in.

If it’s not, make sure to take it out, unscrew any fasteners, and re-install the panel. The new thermostat panel should stay flush with the wall plate.

Even if the panel isn’t loose, I highly recommend to gently pull the thermostat panel and reinstall it for good measure. While you’re doing so, make sure to follow the second step.

Step 2. Check the Thermostat Wiring

So while you’re unplugging the thermostat panel, it’s a good idea to check the thermostat wiring for loose connections or damage and verify the thermostat settings are correct.

The wiring configuration may vary based on your system setup, but always check for the red-colored R-wire and make sure it’s connected securely to the appropriate terminal.

Beyond that, you can check for the black-colored C wire, if your thermostat doesn’t run on batteries. Additionally, ensure the G terminal is properly connected, as it activates the fan to circulate cooler air in your home.To learn more about thermostat wiring, you can check out this guide.

Step 3. Check the Batteries

After checking the wiring, it’s also a good idea to check the thermostat batteries, and possibly replace them if you haven’t done so in a while.

Even in cases of screen flickering, fading, or completely turning off, replacing the batteries might quickly solve your issue.

Most thermostats have batteries and still take power from the HVAC system, but some models work only on batteries. Nevertheless, replacing the batteries is always a good idea.

Also, don’t forget to check out my extensive guide on how to replace batteries for all Honeywell thermostat models.

Now, reinstall everything and see if the thermostat lights up.

Step 4. Check the Power

If the panel doesn’t power on, even after following through with the steps above, it could be due to an electrical problem. Check the circuit breaker and the lights on your HVAC system, and ensure the thermostat power source is functioning correctly.

Also, look for any safety switches near the unit. If your thermostat has one, make sure it’s flipped to the “on” position.

Step 5. Check Furnace Doors

If your thermostat is connected to a furnace, it is possible that the furnace door is not shut properly. Furnaces usually have a door switch, and some thermostats are extremely sensitive to the furnace door switch as it’s a safety concern. A malfunctioning furnace door switch can prevent the thermostat from working properly.

Check if doors are closed and sensors and indicators are working. If the door switch is broken or seems to have damaged wires, you might need to get it replaced with the help of a technician.

Step 6. Check the Voltage in the Thermostat Wires

If you’re comfortable tackling electrical components yourself, and you already have a multimeter on hand, you can check the thermostat voltage by measuring the DC voltage coming in from the HVAC system and connecting to the thermostat.

Remove the thermostat panel from the mounting plate and check the DC voltage between the R and C contacts. For most systems, they need to be around 24-30V.

If you find a lower voltage, it might mean a wiring error or fault within the HVAC system, or an electrical problem.

Optional Step: Try Bypassing the Thermostat

If you have access to a tool or a contraption to create a jumper wire, you can try a thermostat bypass.

This isn’t a proper solution per se, but with this method, you can confirm if the issue lies within the thermostat and not the HVAC.

To bypass the thermostat:

• Turn off the breakers for the thermostat and the rest of the HVAC (furnaces, heat pumps, etc.)
• After that, remove the thermostat panel from its wall mount
• Fix one end of the jumper to the R contact and the other end to the AC or furnace contacts. Usually, it’s Y for cooling and W for heating.
• After the jumpers are installed, switch the power back on and see if the HVAC kicks in.

If the furnace or AC unit powers on without any issues, you can safely rule out the HVAC system. Then, the issue is definitely within the thermostat itself.

Conversely, if the HVAC doesn’t work, you might have to troubleshoot it further.

Scenario 2: Troubleshooting the HVAC not reaching the set temperature

In this scenario, your thermostat has an active display that responds to touch, however, the heating or air conditioning system is not reaching its set temperature. In this case, the thermostat may possibly flash an error code or message like “cool on”, “heat on”, “wait”, “waiting for equipment”, or specific thermostat error codes. To troubleshoot, check the thermostat settings and ensure the power source is functioning correctly.

If a specific error code is showing, I recommend checking out this error code guide here.

Step 1. Change the Temperature

The first thing you can do if your thermostat display is on, but doesn’t power on the HVAC, is to adjust the thermostat temperature settings.

So, first, try changing the temperature on your Honeywell thermostat.

Also, make sure the desired temperature falls within the acceptable ranges.

Specifically, set the heating between 40 °F to 90 °F (4.5 °C to 32.0 °C) and the cooling between 50 °F to 99 °F (10.0 °C to 37.0 °C). If you go beyond these ranges, the HVAC won’t kick in.

Step 2. Wait 5-10 Minutes

If your display shows a “wait” message, or flashes “cool on” or “heat on,” you can simply wait it out for five minutes or so, which is known as the thermostat wait time.

This step helps you safely rule out the compressor protection feature.

Step 3. Change the Temperature Mode

However, if the HVAC doesn’t power on after that, try resetting or changing the thermostat mode first. This can help the thermostat reconfigure itself.

Also, if you find that the heating unit works while the cooling does not (or vice-versa) you can easily tell that the issue lies within the component that doesn’t power on.

Step 4. Verify the Temperature Sensor is Working Correctly

In certain situations, although rare, the thermostat sensor inside the thermostat, or the one connected to it, might be malfunctioning. In this case, it’s a good idea to verify the temperature readings using an external temperature gauge to ensure accurate temperature readings.

If the room temperature displayed on your thermostat or smart sensor isn’t consistent with the reading on a thermometer, it might imply the sensor is faulty.

Faulty Smart Sensor

In the case of faulty smart sensors (like the T9 smart room sensor), you can unlink the smart thermostat sensor from the app and replace it with a new one later (or replace the battery in the sensor).

Fault in the Embedded Temperature Sensor in the Thermostat

If it’s the temp sensor in your thermostat that’s incorrect, you might have to get the embedded thermostat sensor looked at by a technician or replace it entirely.

Step 5. Check the Wiring

Weak splices, wrong or loose connections, exposed wiring, or a faulty thermostat may cause issues and prevent your thermostat from working properly.

In this case, isolate the circuit, unscrew the thermostat, and check if the wires are connected correctly to address any thermostat wiring issues, and verify the thermostat settings are accurate.

Check if Y and Y2 are attached to the correct color wire for cooling. For heating, check if W and W2 are attached to the correct color wire.

Also, you may want to verify if there are Rh and Rc wires in your system and whether they are attached to the proper terminals identified by the correct color.

Step 6. Check Individual Components

If possible, you can check all the individual thermostat components of your HVAC, including the air conditioner, air filters.

This might include checking the switches, indicators, fuses, and wiring for your furnace, heat pump, and AC unit, and ensure the power source is functioning correctly, and verify the thermostat settings are accurate.

Final Step: Call in the Experts

When all else fails and your Honeywell thermostat remains unresponsive, consider seeking professional help from a thermostat technician.

A technician can quickly identify and fix common issues, such as damaged wiring, malfunctioning capacitors, obstructed sensors, or blown fuses, while also inspecting components like the compressor, condenser, or fan motor.

Conclusion

A Honeywell programmable thermostat will stop working either because the display is off or the HVAC is not responding.

By following the steps outlined for each situation, including checking the thermostat settings and power source, you can get to the root of the problem and ensure it won’t happen again.

However, make sure to call in a professional support if you’re not comfortable diagnosing electrical components and always follow the proper safety precautions.

This article serves as a thermostat troubleshooting guide to help you address common issues with your Honeywell programmable thermostat.

Features to Consider

Wired vs Wireless

When choosing the best Honeywell thermostat models, you will come across wired and wireless units – it all depends on your preferences. For wired Honeywell thermostats, you will have to place it at an ideal position to ensure the electric cables don’t run out.

However, for a wireless Honeywell unit, you can place it anywhere in the home as it doesn’t depend on long electric cables. Instead, it uses its built-in receiver.

Programmable vs Non-Programmable

You should opt for a programmable unit if you want to set your ideal temperature parameters. Programmable Honeywell thermostat models automatically adjust their temperature in your home based on a pre-determined schedule.

For programmable thermostats, you have the option to choose a 7-day, 5-2 day, or 3-day schedule programming; allowing you to customize each day depending on the unit's capability. A non-programmable thermostat unit on the other end maintains the same temperature settings throughout the day.

WiFi / Smartphone App

If you want to enjoy more features and control of your thermostat, you want to go for a Wifi compatible one. The Wifi connection allows you to control the thermostat through the brand’s Total Connect Comfort App. A Wifi compatible thermostat means that you can connect the thermostat using your home’s existing wifi connection.

When connected to Wifi, you can still control the thermostat through the app using your smartphone from anywhere. This design doesn’t only enhance your convenience but also helps to cut down on energy costs.

Heating Systems Supported – Single Stage, Multi Stage, Heat Pump, Electric

Before you invest in a Honeywell thermostat, you want to ensure it is compatible with the system you want to use it for. Thus, you want to check your wiring to know what type of thermostat to go for.  For example, zoned heating systems work best with programmable or smart thermostats.

For a Wifi connected thermostats, you need a c-wire whilst programmable thermostats require low voltage wires. Alternatively, if you feel confused, you can consult an HVAC professional to assist.

Heat Only / Cool Only or Both

Honeywell thermostat models come with a choice of three common mechanisms, i.e., heating, cooling, or both. Typically, the majority of manual thermometers work with heating systems. 2 stage thermostats offer more features which allows them to cater to both cooling and heating.

You will notice that the more sophisticated you want your thermostat to control the heating and cooling, the more you will spend. Yet, even if you pick a heating or cooling thermostat, you want to make sure it is compatible with your home system.

Available C-Wire

A c-wire, also known as a common wire, is an extra wire used to provide a return path for 24V power for cooling and heating systems. A c-wire is especially important to have for a smart and wifi connected thermostat – you can find some thermostat models that don’t require c-wires.

However, for Honeywell thermostat models, c-wires are required on most Honeywell Wifi thermostat with the exception of the Smart Round thermostat.

9.7

9.3

Sure, we’ll get to talking about the technical features and capabilities of these thermostats, but first, let’s discuss style and design. This is a category where both products really shine! 

The ecobee smart thermostat has a beautiful shape that is neither extravagant nor too harsh or boring. Its lack of sharp edges automatically makes it feel cosy, while its crisp glass display allows for easy viewing and programming. Overall, the smart thermostat will look quite, for lack of a better word, smart, in your home!

The thermostat offered by Honeywell Home is slightly less interesting to look at. The shape is nice and soft, and the white colorway will fit in well with any color variations on your wall. The beauty of the T9 smart thermostat is in its simplicity. If you’re looking for a thermostat that will blend in with the surroundings, this is a great option.

Though both thermostats are beautiful in their design, the Honeywell Home model is slightly underwhelming in comparison to the ecobee.

Programming & Learning Capabilities

8.9

8.9

Finally, we’re getting to the important stuff! Programming and learning capabilities are important features customers look for in a smart thermostat. 

The smart thermostat by ecobee can learn your daily schedule and even give you recommendations that will help lower heating costs. The occupancy sensor will automatically adjust the temperature when you leave the room/house, and again when you return. Programming the thermostat to follow a complex schedule can be tricky, but you can always ask the support team for help, or let the thermostat adjust the temperature automatically.

The T9 smart thermostat by Honeywell Home is quite the opposite. It cannot learn your schedule automatically, so you need to program it yourself. You can choose the temperature for each room manually or let the thermostat do that for you. It does so by using occupancy sensors to detect which rooms are in use. Naturally, the ones that are in use get the most comfort, be it heat in the winter, or cool air in the summer. 

Smartphone App

9.1

9.3

One of the features that make a smart thermostat smart is the official app you can use to control the device. Of course, both ecobee and Honeywell Home have their very own apps that make changing the temperature in your home easier than ever.

The ecobee app not only lets you control your indoor climate, but also offers a myriad of other helpful features. These include notifications sent when the system needs maintenance. You will also get a notification if the temperature in your house has become dangerously low which can lead to frozen or burst pipes. 

Honeywell Home lets you monitor the usage of all your Honeywell Home devices. You will get a handy reminder when you need to change the air filter, as well as when temperatures fall or rise way above the norm, leading to possible problems. Your thermostat can also determine when you’re home or away using your phone’s location. It can then adjust the temperature automatically and shave a few dollars off your electricity bill for the month.

What Does “Wait” or “Waiting for Equipment” Mean?

When you see “Wait” or “Waiting for Equipment” on your Honeywell thermostat, it's signaling that the system is currently in a safety delay.

This built-in safeguard pauses the operation of your HVAC equipment, specifically, the compressor, to allow for a proper cooldown and reduce the strain on the hardware.

Implementing this pause prevents the equipment from quickly cycling on and off, which could lead to premature wear and eventual damage, especially when the system is recovering from abrupt power failures.

In some models, this will also indicate Wi-Fi connectivity issues. I'll talk more about that later on.

Type 1: Troubleshooting Issues with the HVAC System

Apart from the compressor protection feature, the wait error message will stay on when the rest of your HVAC system doesn’t respond.

So if the blower doesn’t bring in cold/hot air, and the AC, furnace, or heat pumps don’t seem to kick in, It can indicate a hardware fault. 

So, let’s get into the troubleshooting process of fixing a Honeywell thermostat with this type of “wait” or “waiting for equipment” error message.

Also, in a similar fashion, learn how to fix the Honeywell thermostat flashing “Cool On” or “Heat On” issue here.

Step 1: Wait it Out!

If your Honeywell thermostat displays the “Wait” signal, allow it up to 5 minutes to clear.

It might clear out sooner or even take an extra couple of minutes, so I highly recommend giving it a solid 10 minutes so you can verify the issue is not the compressor protection feature.

Step 2: Change Batteries

If the “Wait” message persists for more than 5-10 minutes and your HVAC system remains inactive, you'll need to start troubleshooting the issue.

You can begin by replacing the thermostat batteries. Take out the thermostat from the mounting plate and take out the batteries at the rear panel.

Low battery power can prevent the thermostat from effectively communicating with your HVAC system, resulting in a lack of heat or cool air.

Step 3: Check the Wiring

At SmartHomePerfected we always advise readers not to undertake any work they are not competent in performing and if, in any doubt, it is best to seek the assistance of a professional.

For thermostats relying on 24 VAC power instead of batteries, the wiring may require inspection.

To do so, first, turn off your system's power to safeguard your equipment. Then, remove the thermostat and examine the C-wire for proper installation.

Step 4: Reset Breakers

If your thermostat is not working even after changing the batteries, resetting your HVAC equipment via the circuit breaker could be the solution.

This can help address possible issues within your equipment's circuits and connections.

By resetting the breakers, you're essentially resetting the system and ensuring smooth communication between your thermostat and HVAC equipment.

Step 5: Check the Thermostat Voltage

If the issue persists, consider resetting the circuits connected to your thermostat for an extended period (30 minutes) before moving on to the next step.

The problem may lie in the fuses or wiring, such as a short circuit.

To determine this, use a multimeter to test voltage levels in the thermostat wires. Beyond that, you can also check the continuity in the different fuses, breakers, and switches in your HVAC system. 

Only diagnose electrical components yourself if you have the necessary expertise. If you're unsure or unequipped to handle the situation, it's best to call in a professional.

Final Step: Call in the Professionals!

If you’ve carried out all the steps above and the “wait” or “waiting for equipment” error message doesn’t seem to clear out, it’s best to call in an HVAC specialist.

A professional will be able to troubleshoot more complex issues within your HVAC system and fix it before the day is up. 

Type 2: Wi-Fi-related “Wait” Errors

In certain models, the “wait” message can also pop up while your Honeywell thermostat is trying to establish a secure connection to your wireless network.

This typically occurs when the thermostat is verifying your home's Wi-Fi network or attempting to connect to Honeywell servers for updates.

The entire process should only last a few moments; however, connectivity issues can arise.

If you find yourself waiting for an extended period or notice an error message, it's a good idea to follow up with the following network troubleshooting steps:

Step 1: Restart the Wi-Fi Router

Restarting the router can be a simple yet efficient solution.

Step 2: Restart the Thermostat

Restarting your thermostat is another effective method to help clear out any glitches or software processes that are stuck.

Keep in mind that the restart process may slightly differ between various thermostat models.

If you want to find the exact steps for your specific Honeywell thermostat, don’t forget to refer to our list of collated Honeywell user manuals.

Step 3: Reset Wi-Fi Settings on the Thermostat

Try resetting the Wi-Fi settings on your thermostat. This will clear the connection information.

There are different steps for different thermostat models. Here’s a helpful link on how to reset the Wi-Fi settings of your thermostat. Look for the Wi-Fi Reset instructions in your specific model’s section. You can also refer to your thermostat’s user manual as mentioned above.

After resetting the Wi-Fi settings, you’ll have to reconnect to your Wi-Fi network.

Wrapping Up

The “Wait” or “Waiting for Equipment” message usually shows up as a protection feature. It will usually go away after five minutes or so. 

However, if the message doesn’t clear out, you might be having an issue with the HVAC system not powering on. You can troubleshoot it yourself or get the help of an HVAC professional.

What is a temporary hold and how do I turn it on?

The temporary hold feature, lets you suspend a programmed schedule. This is so you can adjust the current temperature to your desired level until a certain time. You will be able to input how long you want the “hold” to continue, usually up to 11 hours. 

Some models without this function will resume the schedule on the next programmed period (your display might indicate a “Hold Until” time).

For most models, you can easily turn on a temporary hold by pressing the +/- or up/down buttons. If it is available, you will have the option to set a Hold Until time, giving the hold a fixed period.

How to turn off a temporary hold

If you change your mind, you can cancel the temporary hold at any time to resume your usual thermostat schedule. 

This can be done easily by pressing Run, Cancel, Run Schedule, Use Schedule, Remove Hold, or Cancel Hold, depending on your Honeywell thermostat's model. 

Other models might have a ↵ button instead, for canceling the hold. If you are finding any difficulty in doing this, you can refer to your user manual/guide for instructions. Click here to find the user manual for your Honeywell thermostat.

What is a permanent hold and how do I turn it on?

The Honeywell thermostat permanent hold feature, unlike the temporary hold, lets you manually set the temperature. This is for an indefinite amount of time, overriding the programmed schedule completely.

For earlier models, this was the only temperature hold option where you press the HOLD button and then toggle the keys to set your desired temperature.

If you have the newer Honeywell thermostat models, such as those with touchscreen functionality or an app to configure your settings remotely, you can press +/- or up/down buttons to override the thermostat schedule.

Afterward, check from the options below to see which steps apply to your Honeywell thermostat model:

Benefits of the Hold/Schedule Override Function and When to Use It

The hold function offers significant benefits for users looking to temporarily adjust their thermostat's schedule.

With this feature, you can easily accommodate unexpected changes, such as vacations or last-minute gatherings, without having to completely reconfigure the thermostat settings.

The temporary hold is suitable for when you only require a brief change in temperature, such as during a short nap or a quick lunch with friends at home.

On the other hand, if you plan to be away for several days, the permanent hold feature can help you conserve energy by maintaining a consistent temperature throughout your absence.

Setting your thermostat to a modest level before activating the permanent hold can significantly lower your overall energy consumption, ultimately resulting in a reduced energy bill.

What Does the Flashing “Return” Mean?

According to the default schedule in Honeywell Thermostats, there’s a “Leave/Away” period which acts as a “low-power” mode when nobody is at home.

To save power, the temperature setpoint at this period is not comfortable for users. So just before the next period, which is “Return” or “Home,” the thermostat powers the HVAC system so it reaches a comfortable temperature.  

During this short period, the “Return” message on your thermostat might start blinking. Essentially, it’s not an error message but an alert that indicates that the system is working in advance.

This helps set up a comfortable temperature for when you return. 

Pre-Programmed Schedules

The flashing “Return” message will only show up when your thermostat is following a pre-programmed schedule. 

For the majority of the smart and programmable models, these schedules include four distinct periods: Wake, Leave, Return, and Sleep.

Besides that, Honeywell thermostats have a default schedule designed to cater to most homeowners’ daily schedules and temperature preferences.

This default schedule is shown below:

As you can see in the graphic above, the Return/Home period is set to 6.00 P.M. the time when most homeowners return after work. Also, the “Away” temperatures are decreased/increased to minimize power consumption by your AC or Heat Pump/furnace.  

Customizing Your Schedule

However, this pre-set schedule doesn’t always have to be the norm. You can personalize each of these periods as you see fit. 

For instance, you could set your preferred Wake temperature and time earlier or later, depending on when you naturally rise in the morning.

Similarly, you might adjust the Leave, Return, and Sleep settings based on your daily routines.

Programmable Schedule Modes

As I mentioned previously, not all models have this feature. Different models, especially the non-smart programmable ones, have certain limitations depending on the programmable days of the week.

There are four such schedule modes, these are:

• 1-Week Programming: Set a consistent temperature schedule that’s common for every day of the week, ideal for users who work at home or tend to follow the same schedule every day.
• 5 + 2 Programming: Customize separate schedules for weekdays and weekends, perfect for those who want different settings when they’re at home during the weekend.
• 5 + 1 + 1 Programming: Additional personalization by having individualized settings for weekdays, Saturdays, and Sundays. Ideal for users with variable weekend schedules.
• 7-Day Programming: Gain complete control over your thermostat by setting unique temperature schedules for each day of the week, ideal for users with constantly changing routines.

How to Program the Return Schedule on a Honeywell Thermostat

So, if you’re worried about the default schedule, or prefer to switch things up, this guide will show you how. 

Below, I’ve covered the most popular models with detailed instructions. As such, you’re sure to find a scheduled programming guide that falls in line with your model below.

Via the Honeywell Home App

Before we head into the models, let me walk you through how to set up time-based schedules via the Honeywell Home app. 

“Time” allows you to set the beginning and end times of each period, while “Priority” lets you select which sensors to activate during that time.

Adjust “Temperature” to control heat and cool setpoints, and “Fan” to assign the fan/blower function (on, auto, or circulate) for that period.

On top of that, you can set up geofencing, sensor-based, or smart features in your scheduling process.

These are handy and efficient but can be sometimes overwhelming and you always need to set them up via the Honeywell app.

What is the Honeywell Thermostat Recovery Mode?

Thermostats are programmed to achieve a desired temperature by controlling the connected HVAC system. It can take time from triggering the HVAC system to heat or cool, for the ambient room temperature to hit what has been set on the thermostat.

The Honeywell Thermostat recovery mode allows the HVAC system to start heating/cooling before the scheduled time to achieve the planned ambient temperature when needed.

This feature goes by various names, such as Adaptive Intelligent Recovery, Smart Response, and Early Start. It’s also similar to the flashing “Return” mode in older models. 

Without it, your thermostat would disappoint by only starting heating or cooling at the selected time and then taking an hour or two to achieve your desired temperature!

Intelligent Recovery Mode

In smart models, the thermostat really takes the “intelligent” feature to heart as it learns and optimizes the recovery mode so it’s more efficient and tailored exactly to your home’s climate.

Unlike the older models, it won’t always start an hour in advance. After a week or so, it will learn how to readjust itself more efficiently. 

So the early start-up time can be less than an hour or even more. Whatever the case, it will always reach a comfortable temperature at the allotted time.

Situations Where the Recovery Mode is Helpful

The Recovery mode or adaptive recovery is extremely useful when the system is recovering from the “Wake” or “Away” time periods on your schedule. 

For example, if you want your room temperature to be 72° at 7 am. The recovery mode will instruct the thermostat to start heating your room around 6 am which gives the system a full hour to bring the room up to 72°.

Similarly, in Summer, when you have set your thermostat to a lower temperature for the time you return from work, it starts cooling your room before time.

In essence, Honeywell Thermostat Recovery Mode proactively adapts to both your schedule and your home's temperature needs, maximizing efficiency and convenience.

Benefits of Recovery Mode

There are numerous benefits of the Honeywell thermostat recovery mode.

1. Designed to save energy

For most two-stage style HVAC systems, the recovery mode is designed to be energy efficient. 

Instead of quickly generating and blasting warm or cool air throughout your home, the system gradually alters the temperature up or down.

These incremental changes help put less strain on the system, making it more energy-efficient. 

2. Comfort and Convenience

Using the Honeywell Thermostat recovery mode will provide you comfort by attaining the desired temperatures when you need it. 

Depending on inside and outside conditions, the time it takes to warm up or cool down your home can vary throughout the year. The recovery mode can adjust the time it takes to pre-warm or pre-cool, based on these factors.

Outside of the recovery mode, you can program your thermostat easily so that it works when you need it and remains off when you are out.

3. Less Load on the HVAC System

The Honeywell recovery mode or “Adaptive Intelligent Recovery” system places less load on an HVAC system by not requiring sudden calls for large intense amounts of warm or cool air. This is particularly important for two-stage heating or cooling systems. 

Regular sudden temperature change requests put a heavy load on an HVAC system and this can cause unnecessary wear and tear on the system. 

How to Override or Disable Recovery Mode?

The recovery mode is enabled by default, but you can disable it if needed. 

Below I’ve listed model-specific instructions on how to disable it. You can check these guides or reference the user manual for your specific model here.  

T10 Pro and T9 Models

Smart thermostat with a color touchscreen

For the T9 and T10 models, you need to head into the preference menu options to disable the intelligent adaptive recovery feature. Here’s how:

FAQ

How Long Does it Take for the Recovery Mode to Learn How to Reach the Programmed Temperature?

For the smart models, it usually takes around a week to adjust itself to achieve the perfect temperature at the correct time. This might take longer if the climate is inconsistent.

What are the Disadvantages of Recovery Mode?

In certain instances, recovery mode can become a disadvantage, especially if you don't want the AC or heat pumps kicking in before the set time periods in your schedule. For example: if the HVAC system is particularly noisy, it can be distracting. 

Also, the recovery mode might not always be energy-efficient so to get the most effective use out of recovery mode. As such, it’s always a good idea to adjust the schedules according to their circumstances instead of relying on the default setup. 

Does Recovery Mode Get Disabled by Manual Override?

Yes, it gets overridden when you set up a permanent override. However, it will start back up in the next cycle in the case of temporary override schedules.

What is Short Cycling?

Short cycling is a phenomenon that happens when an air conditioning or heating system is unable to complete a full cooling cycle.

A complete cooling cycle starts when the air conditioner turns on and ends when the thermostat's set temperature is reached, and the unit turns off again.

When a system is short cycling, it can’t achieve a comfortable temperature since the system switches on and off repeatedly without improving the temperatures.

This not only increases energy consumption, leading to higher bills, but it also puts unnecessary strain on the system, causing your filters and equipment to wear down faster.

How To Confirm If Your Honeywell Thermostat is Short Cycling?

Here's how to confirm if your system is experiencing short cycling: 

What are the Long-Term Issues with Short Cycling the Honeywell Thermostat?

Long-term issues with short cycling can lead to increased energy consumption, higher electric bills, and excessive wear on your thermostat and HVAC system.

This extra strain can result in premature component failure and higher maintenance costs, while also negatively impacting the overall comfort of your living space.

Also, the system might not be able to achieve comfortable temperatures since it’s constantly short cycling.

Compressor Protection Feature

The compressor protection feature allows the smart thermostat to prevent the compressor from starting up for a brief moment, safeguarding it from potential damage.

When engaged, the thermostat screen displays “Waiting for Equipment,” or on older models, you may see “Wait,” a flashing “Cool On,” or “Heat On” message.

This feature can help minimize short cycling but only when the system is recovering from a power outage or when the temperature is adjusted manually or via the schedule.

If the “Waiting for Equipment” message persists longer than five minutes, there may be an underlying issue present. 

In that case, check out this guide for more information.

Reasons for Honeywell Thermostat Short Cycling

There can be several reasons why your Honeywell thermostat is short-cycling. It can be due to an issue with the thermostat or the rest of the HVAC system. 

First, we'll get into the thermostat and then start tackling the rest of the system.

At SmartHomePerfected we always advise readers not to undertake any work they are not competent in performing and if, in any doubt, it is best to seek the assistance of a professional.

Reason 1. Thermostat Running Out of Batteries

When a Honeywell thermostat's batteries are running low, you will be notified in advance or you may experience screen flickering or glitches.

Because of low batteries, the thermostat might be floating in and out of the system, sending signals intermittently to the heating or cooling equipment.

Therefore, replacing the batteries as soon as possible can help prevent short cycling and maintain the thermostat in optimal condition.

Reason 2. Loose Connections in the Thermostat

Loose connections within a thermostat can lead to short cycling in heating and cooling systems.

To tackle this issue, take out the thermostat from the wall mount and inspect the wiring strip and terminal block to make sure all contacts are secured firmly.

If possible, try removing the wires from the contacts and reinstalling them for good measure. Make sure you have the proper tools and clean the contacts from any dust or debris.

Also, make sure the wiring configuration is correct, with the wires neatly aligned to their corresponding contacts.

Additionally, check the thermostat strip on your furnace's control board and confirm the wire connections there are secure as well.

Reason 3. Low Voltage in the Thermostat

Wiring issues can result in reduced voltage, specifically among the R and C wires which provide 24V AC power to your thermostat (for models that don’t run on batteries or use them for emergencies only).

It is essential to test the incoming voltage to ensure your thermostat receives the required 24-30V AC power.

If you have a multimeter and you’re comfortable checking the voltage from the thermostat contacts, you can try this out yourself. Otherwise, it’s best to get help from a professional.

Reason 4. Faulty Indoor Temperature Sensor

Although rare, the indoor temperature sensor in your Honeywell smart thermostat can malfunction or take incorrect measurements, leading to short cycling.

Faulty Thermostat

To determine if the sensor is the issue, compare the thermostat's temperature reading with that of a separate thermometer.

If there's a discrepancy between the two readings, your sensor might be to blame.

Placement of the Thermostat

Another potential cause of inaccurate temperature readings is the placement of air vents, windows, or any other equipment (such as computers, or air fryers) that can change the temperature in the immediate area surrounding the thermostat.

This equipment and fixtures can cause the internal temperature sensor to be measured inaccurately, causing short cycling with the thermostat and sending the wrong signals to the rest of the HVAC equipment.

Moving a thermostat to a different location is not the best course of action. Instead, I recommend moving the equipment or blocking the vents that are within the thermostat's immediate vicinity.

Bypassing the Thermostat

To further investigate, you can try bypassing the thermostat entirely. If your furnace or AC runs without short cycling in this scenario, it's definitely the thermostat that’s causing all these issues.

Beyond that, you can try resetting the thermostat.

Reason 5. Clogged Air Filters or Blocked Vents

Restricted airflow into your furnace or HVAC system can cause the temperature and pressure sensors in your HVAC system to toggle on and off repeatedly.

To avoid this problem, change or clean your filters regularly.

Blocked vents can also contribute to this, so when dust, debris, or foreign objects block the intake or return vents, only a fraction of the air can enter your furnace or system.

It's important to check for any obstructions in your vents and remove them as needed.

Reason 6. Dirty Evaporator Coil/ A Coil

A dirty evaporator coil can cause short cycling due to dust accumulation, which restricts airflow, creates low pressure in the refrigerant, and trips the low-pressure switch.

To resolve this issue, clean the coil yourself or get a professional to do it. Also, consider having your ducts cleaned as well.

Reason 7. Low on Refrigerant/ Refrigerant Leak

A refrigerant leak or low levels of refrigerant in your Honeywell thermostat can lead to short cycling.

Topping up the refrigerant from time to time is only a temporary solution so it’s a good idea to address the leak or any other underlying issues with the help of a professional.

Reason 8. Oversized HVAC System

An oversized HVAC system can lead to short cycling issues with your Honeywell thermostat.

To resolve this issue, you can try reducing the blower speed fan, which will decrease the cooling speed and allow the system to run longer, which can help cool the house more evenly.

However, for a more accurate and long-term solution, it's best to consult with a professional HVAC company to perform a heat load calculation and get advice on how to optimize the system.

Reason 9. Dirty or Damaged Flame Sensor

A dirty or damaged flame sensor presents a significant problem as it can directly contribute to short cycling.

This not only impacts your home's comfort but also affects its efficiency, leading to increased energy consumption and costs.

Reason 10. Bad Contactor Relay on the Compressor

A bad contactor relay on the compressor can lead to short cycling, as it might be faulty or the contacts might be dirty or blocked.

If possible, you can try checking the voltage on the contactor. You should get 24V AC to ensure it's receiving adequate power.

If you encounter any issues, I highly recommend replacing it or getting an HVAC technician to take a look.

Reason 11. Partially Clogged Drain Line

When the drain line, is clogged up, the air conditioner's float switch – responsible for monitoring possible clogs – turns off the system to prevent overflow and potential leaks.

So if the drain line becomes partially clogged, it might trigger the float switch unnecessarily, resulting in your air conditioner short cycling.

If you find this to be the issue, make sure to unclog the drain pipe using a wet/dry vacuum, drain cleaner, or a tool such as a plumber's snake.

Reason 12. Compressor That’s Failing to Start

Another common example of short cycling is when the fan activates, but the compressor only hums for a few seconds before shutting off.

There can be several reasons but the most being that the compressor is failing to start.

To remedy this, you can try replacing the dual-run capacitor or installing a hard start kit.

However, it could also be an underlying issue with your compressor. In this case, it's crucial to contact a qualified HVAC technician for further assistance.

Other Reasons

Apart from the ones mentioned above, there can be several other reasons why your smart or non-smart thermostat is short cycling: 

• Damaged Transformer
• Power Fluctuations
• Faulty Control Boards
• Electrical Short 
• Bad Condenser Fan Motor
• Dirty Evaporator Coil
• Higher Cycle Rate in Thermostat

If possible, try rectifying these yourself, waiting it out, or getting help from a professional.
