Checking compatibility from photo of old thermostat for nest thermosta

Hey mike1,

I would be more than happy to help you out and see if your system is compatible. You can use our Compatibility Checker to enter the wires you are seeing, and it will provide you with which devices you are compatible with. Please let me know if that helps, or if you have any other questions from here.

Best regards,

Jake

Hey folks, 

It looks like we have come to a solution so I'm going to be locking this thread. If you have any other concerns or questions, please feel free to create a new thread. 

Have a great day.
