From an initial look at your wiring, it may not be compatible with that thermostat model, not without modifying the wiring at least. To confirm, go to the Contact Google Support page and select Chat or Phone. You can share the photo of your thermostat wiring with a Google support agent.
The best thing to do is use the online compatibility checker, but from experience it will tell you to contact Google support, as your thermostat uses wires which aren't very common, such as the B/C wire, and AUX wire. They'll be able to check compatibility with you.

Perfect! I'm glad to know that your thermostat is now up and running. So it looks like we've come to a solution, and I am going to lock the thread at this time. If you have any questions, please feel free to create a new post.
