Hi jawlee,

 

Thanks for posting here in the Google Nest Community forum. I'd be happy to shed some light on your situation here. Two-wire systems can work with our Nest Learning Thermostat but before we install it, we wanted to check a couple of things. Please answer the following:

  1. Are you from North America or Europe?
  2. Send us a photo of your HVAC wiring so that we can verify the wire before connecting it to the Nest Thermostat.
  3. Is this the first time you'll install a Nest Learning Thermostat? 

I look forward to your response. 

 

Best,

Renz
