nest thermostat compatibility question

[grovesju]

This thermostat controls central air ONLY.  Is Nest compatible?

Yes, it will, but you must take the spare blue (or black) wire and connect it to the C terminal in the air handler and at the thermostat.

Hi grovesju, 
 

Thanks for posting here in the Community forum. I’d like to take a look at this for you. 
 

Can you help me with the make and model of your HVAC system and a photo of your furnace control board where the other end of the thermostat wires are connected? 
 

I’ll look forward to your response. 
 

I appreciate your help, @Patrick_Caezza. 

Best,

Zoe
