Hi, @Jaeger!
Thank you for reaching out to the community. I appreciate the detailed wiring information you’ve shared. I’m happy to help!
Based on the information provided, your system is compatible with all Nest Thermostat models. The E/W wire indicates you have emergency heat. This wire typically connects to the star connector terminal (*).
To determine the exact compatibility, please provide the following:
- Please provide a photo of your previous wiring installation. This will help me visualize the wire connections.
- If possible, a picture of your control board. It's usually located near the furnace. It will help me determine whether the W/E wire corresponds to emergency heat or the first stage of heating.
Additionally, please refer to this article to identify your thermostat model: How to tell which Nest thermostat you have.
Please keep me updated.
Best regards,
Ana
