    Can you furnish the make and model of each stat? Is this a heat pump system?

    Need to know more about your heating cooling system, describe it.

    Are you telling me the stat is GE? Where did you see GE on the stat?

    "Weathertron" is a old brand name of Trane equipment. If you have a Trane system you may need to contact a Trane dealer to find the correct stat. Also sounds as if you have a heat pump system, I asked but still not sure what you have. A heat pump system will have auxiliary electric heat that must be controlled also along with the compressor, important to know which control wires are for what.

    Pro 8000 is a Honeywell series, and not the model number.
