The diagram s to connect to the system that has the ” RI+ I- C” Wall connector Red(R) Green (G) White (W) and Common (C) is not shown on any of the thermostat. Why? All other Thermostat , even the ones that require the “C” wire gives you a connection diagram, from the $13.95 -the $459.99 ones. Your M-30 will never come loose from the wall. shows great instructions to connect the stud. nothing about how to connect the wires from the wall to the thermostat.
