Hi, I would like to replace my old honeywell thermostat by a nest gen 3. There is only 2 wires. 1) is it possible to replace ? 2) how to wire the 2 actual wires
Hi My understanding of the new type of heating controls is that a base station / receiver / programmer is wired in the system wiring Center. The wall thermostat can be battery powered, and rf connected to the base station, so the two wires you have aren’t needed, and you can fit room stat, anywhere ? Good luck Peter
