Wiring compatibility

I need to know if my thermostat is compatible with the nest learning thermostat third generation:

I do not see an option to attach a photo but my old system had

  • a black wire on W-2
  • A red wire on RC
  • A white wire on O
  • a yellow wire on Y
  • a green wire on G
  • a blue wire on B

can anyone tell me if this is compatible? If so, where should the new wires go on the new system?

Hi @Ktmcrthy,

 

Thanks for posting in the community. I understand you're looking for help to determine if your current thermostat's system is compatible with the Nest Learning Thermostat (3rd gen). I appreciate that you've shared the information about your wiring system. No worries, I'd be more than glad to share more details with you.

Based on your wiring information, it appears to be compatible with the Nest Learning Thermostat. However, to be completely sure about how to wire it, could you please share a picture of your current wiring installation? 

You can upload the picture by clicking on the "camera icon" before sending the reply. This information will help me to visually confirm the wire terminals and provide you with a more accurate installation guide.

Please keep me posted.

 

Regards,
Jonathan
