Compatibility with Cooling only unit

[Fremagora]

I want to know if i can install a nest thermostat, my unit has Y,R,C,O,B, H1,H2.  I think it is 24V, i attached a photo of the board. I’am curious that it dosen’t have the “G” wire that is from the fan!

Hi Fremagora,

Thanks for posting in the Google Nest Community forum. I'd like to take a closer look at it. Could you please provide your system make and model? It will help us to ensure the compatibility of your system to the Nest Thermostat, and identify the type of system you have.

Best,

Jenelyn
