Nest Thermostat Compatibility

[Anna13]

Please let me know if the best learning thermostat will work with my system.

Yes, the Nest Learning Thermostat, 3rd Gen will work just fine.

It looks like your system is set up as a 1-stage cooling, and 2-stage heating.

Try this wiring

White - W/E to W1

Black(?) - W2 to W2

Red - RH to Rc

Green - G to G

Yellow - Y to Y1

If there is an extra wire hidden, I suggest you use it for a C wire.

We did that wiring but now it is having an issue with not enough power. What should we do about that?

Do I need to install the Nest Power Connector?

Hi folks,

@Patrick and @aatienza, thanks for the help!

@Anna13, I'm sorry to hear that it's having an issue with power. Having the Nest Power Connector would give your Nest Thermostat consistent power. Could you share the power readings of your Nest Thermostat? You can find this information by going to your thermostat's Settings > Technical Info > Power.

Thanks,

Edward
