Thermostat Compatibility

Community Member

I’m thinking of purchasing a Nest Thermostat and working on determining if my system is compatible. I’m unsure if my system meets the wiring requirements for a Nest Thermostat. Would anyone be able to assist?


The labels on the wires coming into my thermostat are the following:

R, W2/X2, W1, Y, G, O, B

Hi @Austinhuff - That looks EXACTLY like the same setup I had before I switched over to the Nest Thermostat.  The only thing that I needed to get was the Nest Power Connector to hook up down in the heater control panel in my basement. You can find that here:

I suggest trying to install it without the Power connector first - the home app will let you know if you need a connector during the initial setup. 

Hope this helps!

Yes, it is compatible with any of the Nest Thermostats

Try this wiring with the Google Nest Thermostat

Red - R to R

White - W1 to W (jumper to W2/X2 not needed)

Yellow - Y to Y

Green - G to G

Orange - O to */OB

Blue - B to C


When asked by the Home app to select the wires being used, I suggest these.

R, W/W1, Y/Y1, G/G1, O, and C
