Well I can seem to figure out how to upload a picture on this thread as it seems I need a url?

Hi Picarello, 

 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Are you located in North America or Europe? You can send a photo of your current thermostat wiring configuration here at this link. Tap the camera icon or click the three horizontal dots to expand the toolbar to reveal the camera icon, where you can send us the photo. Also, you may use our Compatibility Checker to determine if a Nest Thermostat is compatible with your heating and cooling system.

 

Keep us posted.

 

Best,

Zoe

I’ve uploaded a picture. From my computer at the time I didn’t have the upload picture icon. Just the url link in the expanded toolbar. I am in the United States. Let me know if you can help now.  Thanks.

Hi there,

 

I got the photo you've sent—fortunately, your thermostat wires are compatible with our Nest Learning Thermostat 3rd generation and Nest Thermostat E and should be wired to their bases as follows:

 

  • Yellow wire to Y or Y1
  • Green wire to G 
  • Orange wire to *OB/OB
  • Red wire to R or RC/RH
  • White wire to W or W1

 

Also, here's a guide for the installation and setup of a Nest Learning Thermostat 3rd generation and Nest Thermostat E. 

 

Let us know if that helps.

 

Best,

Zoe
