Wiring Compatibility from Trane tcont802as32daa to Nest Learning Gen 3

[QuiksilverOKI]

I’m looking for some assistance in wiring for the Y2, F, X2, and W1 into the gen 3 system. I’ve been told this is compatible but trying to make sure before installing. I already own the Gen 3 from a previous house and the wiring is different.

Hello QuiksilverOKI,

Thanks for posting here in the Community. Based on the photos of the wires from your current thermostat, this is a heat pump system. This should be only compatible with 3rd Gen  Nest Learning Thermostat. But could you please give us the make and model of your system since another wire for the fan control? 

I look forward to your response. 

Best,
Edmond

I have Gen 3 Learning Thermostat. Are you looking for the make and model of the actual HVAC unit?

Hi there, 

I’m sorry for the confusion. We need to get the make and model of your HVAC unit to verify the correct wiring configuration on the Nest Learning thermostat.

Best,
Edmond
