I don’t believe I have a heat pump. Traditional furnace in the attic and
air conditioner on the exterior of the house (live in TN if that’s
helpful at all). does that change any of the wiring?
My upstairs thermostat is the same, EXCEPT, the upstairs thermostat
wiring does not have orange “O” wire. How would I wire this one and is
it compatible with the Google nest learning thermostat?
