Is my thermostat wiring compatible

[Dmurph88]

Hello - wondering if existing thermostat is compatible and how to deal with the 2 capped wires for NEST. Do I connect them?

Hi Dmurph88,

Thanks for visiting here in the Google Nest Community forum. I'd be happy to take a look at this for you. The two capped wires are for a cooling system, we can connect them to the Nest Thermostat, but we need to check if the other ends of the yellow and green wires are connected to your AC.

The red and white wire is compatible with our Nest thermostat.

You can go to this link for Nest thermostat compatibility to make sure that your system is compatible with the Nest thermostat. You may also use our compatibility checker.

Keep us posted.

Best,

Renz
