Hi justininglis,

 

It's nice to see you here in the Google Nest Community Forum! I'd be happy to check into this for you.

 

The conventional thermostat terminals you have are compatible with Nest, and the B terminal is typically for 24V common. To make sure, could you please share a photo of the wiring on your thermostat? Which country are you posting from? Is your system a heat pump as well?

 

Keep me posted.

 

Best,

Mark
