Thermostat e TD023 error on setup

[Moodygaz]

Just got 2 thermostat e’s for rental properties

one I’ve setup with no problems, the other returns a TD023 error on setup, tried it with a different phone and also in my own house but it still won’t connect, also pressed dial in for 10 secs to reset and still not working, house  logo comes up and that’s it. any ideas anyone?

The TD023 error can occur when your thermostat is unable to connect to your phone or tablet over Bluetooth Low Energy (BLE). 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.
3. Reset the account connection on your thermostat. Note: Reset of account connection varies on different thermostat models. Make sure to do a reset connection, and not perform a factory reset of your device.

Thanks for the response 

since it’s the initial setup from new, I don’t have a ‘settings’ option on the thermostat yet to enable a reset
