Another compatibility Check

[TarTah]

I want to check if my system is compatible with Nest Thermostat.

I only have three wires, white, black and red. I would appreciated any feedback.

Hi TarTah,

Thanks for visiting the Community.

We appreciate the photo you've shared. Could you please tell us what type of system do you have? By any chance, do you know where the black wire is connected? 

You may try removing the cover of your current thermostat to see the label of the black wire where it is connected? We'd love to know more details about this!

Best,

Princess
