What Should I Do If My Hard Wired Thermostat Says “Thermostat Unplugged”?

Answer

If a “THERMOSTAT UNPLUGGED” message appears on your thermostat’s screen or in your app, it indicates that your thermostat has been disconnected from its backplate.

When your thermostat is unplugged, it cannot control your boiler. Consequently, your heating will immediately switch off and remain off until the thermostat is reconnected.

  
To resolve this issue, follow these steps:

  1. Reconnect Your Thermostat: Push your thermostat firmly onto the backplate until you hear a click. This indicates that the thermostat is securely in place and should display the inside temperature.

      
  2. Check the Retaining Screw: If your thermostat does not click into place, ensure that the retaining screw on the backplate is fully tightened.

By following these steps, your thermostat should resume normal operation and control your heating system effectively.
