Exactly right but I'll include the detailed steps below. Before you reset your old thermostat, you'll probably want to write down the wiring information so you can easily enter it again. On your thermostat, go to the Settings cog > Equipment. You may want to do this for other settings such as system heating type and safety temperature as well.
- Sign in to the Nest app.
- On the app home screen, tap the settings cog.
- Tap your thermostat.
- Scroll down and select Remove.
- You'll then be asked to confirm your choice.
- When you're ready, on the thermostat itself, go to the Settings cog > Reset > All Settings.
Once reset, switch off the power to your system and remove the thermostat from the wall.
- On the Nest app home screen, tap the settings cog.
- Scroll down and select Add product to start the setup instructions.
- To tell the app which thermostat you’re installing, scan the QR code on the back of your new thermostat. Or choose “continue without scanning” and select your thermostat model.
- Follow the rest of the steps in the Nest app.
Enjoy your new thermostat!
