Thermostat Compatibility Check -

[JohnS23]

I am looking to replace my current thermostat which is a Honeywell Focus Pro 500 with the Nest Thermostat.  Can someone confirm if Nest will work and which model?  Thank you!

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

I would suggest wiring it like this.

White - AUX/E to W2 or W

Green - G to G

Orange - O/B to OB or */OB

Blue - C to C

Red - R to Rc or R

The "or" is for the Google Nest Thermostat
