The TD023 error typically occurs when your thermostat is unable to connect to your phone or tablet over Bluetooth. This can happen because:

  • Your thermostat isn’t powered on.
  • Your thermostat is outside of Bluetooth range.
  • Your thermostat is already added to another account.

 Follow the troubleshooting steps below.

  1. Make sure that the thermostat is powered on.
  2. Move your phone closer to the thermostat and make sure Bluetooth is turned on.
  3. Reset the account connection on your thermostat. Go to Settings > Reset > Account connection.
