Need help determining if Nest thermostat is compatible with my hvacs. I have three split through the condo built in 1979.
One was setup with Thermostat before we bought it. Before I have someone come in to install Nest for all three, I want to make sure it's compatible. Pictures show the model as:
McQuay-Perfex Inc. Fan-Coil Unit 374N, Model #: HSB-060B-N-A, Serial JF01736
There are connections behind the wall that are connected with wire nuts as you see in pics, but I know that doesn't necessarily mean it's compatible with the Nest thermostat.
Any help here is greatly appreciated!
