Hi, @dl1107,
Thank you so much for posting in the community. I'm happy to provide you assistance with your thermostat installation and setup process.
To identify how to connect the white wire, please share the following:
- The thermostat model; refer to this article to get it: How to tell which Nest thermostat you have.
- A picture of your old wiring configuration.
- If you're comfortable, please also share a picture of your control board (usually located next to the furnace).
Based on the information, I'll be able to help you about where to insert the white wire.
Please let me know if you have any questions.
Best regards,
Ana
