Incompatible thermostat wiring for Nest 4th Gen

Thursday

Hi, I am trying to replace my current A/C heating thermostat with a Nest 4th Gen one. In the App I was told that my wiring system is incompatible without any further explanation. I am curious if there is a fix. Here are the wires I have:

G, RC, RH, W/B and Y/0 - Simple A/c and gas-fired heater.

Any ideas are most welcome. Thank you.

Hello @Ramina, 

 

Thanks for reaching out to the Google Nest Community Forum. I understand that you are trying to replace your current A/C heating thermostat with a Nest Learning Thermostat (4th gen); however, the Google Home app has indicated that your wiring may not be compatible. Don't worry; I'm here to help.

To provide you with the most accurate information, could you please share a picture of your current thermostat wiring system? These details will be helpful in reviewing the compatibility. 

If you have any additional details, don’t hesitate to share them with me. 

 

Best regards, 

Daniel
