Thanks for posting here in the community and for your interest if your HVAC system is compatible with the Nest Thermostat. To know more about this, do you know what the X2 and T terminals are for? You can check it from your HVAC's manual or if possible, can you tell us the make and model of your thermostat and HVAC system? Also, you might want to check this article to know about the Nest Thermostat compatibility.
Thanks for lending a hand, @EmersonB. @AR6, chiming in to ensure everything is good here. Let us know if you have additional questions ― we'd love to help.
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.
