Thermostat replacement - only 3 wires
Tried searching the forum, YouTube, Google... I can't be the only one with a GE thermostat and air conditioner can I?
I'm trying to replace my thermostat with a Honeywell 5000 with batteries. There are only three wires attached to the back of the GE thermostat; red, white, and blue. No indication on the thermostat which wire is which. I verified with the voltmeter that red is power. White indicates voltage when the thermostat is set to fan.
On the Honeywell thermostat, it indicates the power goes to R and the fan goes to W. But then there are separate locations for heat and condenser. Anyone have a clue how one blue wire would be connected to the Honeywell thermostat?Chad
