Nest Compatibility Photo

Just asking if my system is compatible as advised on the Nest Compatibility Site.

[Patrick_Caezza]

Yes, your thermostat is compatible with any of the Nest thermostats.

Try this wiring

White - W to W1 or W

Red - RH to Rc or R (jumper to RC not needed)

Yellow - Y to Y1 or Y

Green - G to G

The "or" is for the Google Nest Thermostat wiring.

Check and see if there is a spare wire that you can use to create a C wire. If there isn't one, I recommend creating one with the Google Nest Power Connector. Having a C wire will help prevent power issues down the road.

Thanks for the reply.  I'm getting a new furnace installed and wanted to add a Nest Thermostat.  If I am understanding your reply correctly, I need to get the Nest Thermostat C Wire Adapter accessory.  Am I understanding this correctly?

[Patrick_Caezza]

You only need it if no extra wire goes from the thermostat to the furnace.

If you are having a new furnace installed, have the installers run a new thermostat cable with enough wires, so you don't need the power connector.
