Hello Al,
Want to get some help with wiring compatibility with Gen4 Nest Learning Thermostat.
My current Thermostat has the wiring below
Y O/B
G W
C R
Will this work with the Gen4...?
Thank you

Hi folks,
Thanks for posting in the community.
@Patrick_Caezza, thanks for your help in this thread.
@kevinhac, I understand you'd like to know if your system is compatible with your Nest Thermostat 4th generation. Don't worry, I'm here to help.
Based on your information, it seems that you have the necessary wires to make the Nest Thermostat work. However, to better assist you, please confirm what type of HVAC system you have. Also, please let me know if you have a C wire connected or not. To learn more about this, you can check out the following article: Compatibility Checker.
Any additional details you can provide will be helpful.
Cheers,
Jonathan
