Nest Thermostat Not Cooling

BrendanG

I just installed two generation three nest learning thermostats. We have a geothermal system. Our AC worked fine before with the prior thermostat but now it’s not cooling. Below is the picture of the prior wiring configuration. I replicated this exactly with the nest thermostats. Appreciate any tips or tricks!

Hi BrendanG,

 

Thanks for reaching out here in the Google Nest Community.

 

It looks like you have a heat pump system and we could change the OB wire settings by going following the steps here.

 

I hope it helps.

 

Regards,

Ryan

I ended up having to get a professional Nest installer come adjust the settings. It’s working now.
