Trying to connect Nest Thermostat to iPhone

[BarbaraS]

How do I correct the error code TD023 that appears every time I try to connect the iPhone to the thermostat to "add product" to the app? The description says to turn on Bluetooth or turn it off and on which I have done many times without eliminating the error code.

If you've already tried turning Bluetooth off and on, and making sure your phone is within 5 feet (1.5m) of your thermostat until setup is complete, try these steps:

1. On your thermostat, go to Settings > Reset > Account Connection. Your thermostat will restart.
2. Once it restarts, go to Settings > Nest app. It should say "none" if the reset worked.
3. On the Nest app home screen, tap the Settings cog.
4. Tap Add product. The app will switch to a camera view to scan the thermostat’s QR code.
5. On the thermostat, press it again and select QR code. Your thermostat will show you a unique QR code to scan with the app. If it doesn't, tap Continue without scanning in the app and select Get entry key on your thermostat instead.
6. Follow the remaining steps in the Nest app.
