Thanks for posting your thermostat wiring diagram. I'd be happy to take a look into this for you.
It appears to be Nest Thermostat compatible based on its wiring configuration. Please make sure to follow the appropriate terminals for the correct configuration and to avoid power issues. You can also check your system’s compatibility before purchasing a Nest Thermostat with our online Compatibility Checker.
@Susanh1 how's it going with your Nest Thermostat? Were you able to check the compatibility check link that Mark has shared above? Let us know if you have more questions in mind.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
