Hey cokie,
Thank you so much for posting in this community. I understand you have questions about whether your wiring system is compatible with our Google Nest Thermostat models. No worries; it’s a pleasure to guide you through.
Based on the information you provided, I can determine that the wiring system is compatible. To achieve the best performance, I recommend the Nest Learning Thermostat (3rd gen and 4th gen).
Additionally, unlike most traditional thermostats, Google Nest Thermostats don't require jumper wires. If your current thermostat has jumper wires, do not connect them during the new installation process. To get more information, please refer to this article: Learn about thermostat jumper wires.
If you have more questions, please feel free to write in this post.
Best regards,
Daniel
