Help on thermostat compatibility!

YuchenXie — Tue, 03 May 2022 01:50:29 GMT

Requesting help, I am very interested in purchasing a Nest Thermostat, but I am not sure if it is compatible with my home. It now has seven wires already connected and they are R , W/Y, Y/A, GI, Gm, GH, and C.

Yes, your system is compatible with the Nest Learning THermostat, 3rd Gen.

I can't see the colors of the wires at each terminal. Can you post a picture showing them?

You are compatible with the Nest Learning Thermostat, 3rd Gen

Try this wiring

Blue - R to Rc

Orange - W/Y to W1

Yellow - Y/A to Y1

Red - Gl to G

Green - Gm to Y2 (set as 2nd-speed fan relay)

Black - Gh - to * (set as 3rd-speed fan relay)

White - C to C
