I'm stopping by to see how I can assist.
Thank you for your help here, Ken.
@Chachel325, I wanted to follow up and see if you could share with us a picture of your system's wiring diagram. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
Mark, here is the picture that he sent directly to me.
He has a Heat Pump (O), with 2-stage compressor (Y and Y2) and Auxiliary heat (W).

I'm chiming in to see how I can help.
Ken, thanks for assisting and sharing the picture. I appreciate it.
@Chachel325, It appears that it's compatible with the Nest Learning Thermostat. Make sure to follow the wiring diagram so it can be configured properly during the initial setup. You can also check your system’s compatibility before purchasing a Nest thermostat with our online Compatibility Checker.
Please let us know if you have any other questions or concerns.
