Wondering if this setup is compatible with any of the nest devices. Thank you.
It is compatible with any of the Nest Thermsotats.
You can wire it like this.
Blue - C to C
Brown - B to OB or */OB
White - W/E to W2/AUX or W (jumper to W2 no needed)
Red - R to Rc or R
Green - G to G
Yellow - Y to Y1 or Y
The "or" is for the Google Nest THermostat
There is a good chance you will need to do this once you have the thermostat installed.
Change the O/B wire settings
If your system starts to blow cool air when your Nest thermostat is in Heat mode (or if it blows warm air when it's in Cool mode), change the settings for the orientation of your heat pump.
The instructions depend on which thermostat you have.
