    • The available firmware update cannot be installed on my Homematic Radiator Thermostat. What can I do?

      If the update has not been performed successfully, proceed as follows:

      • Remove the batteries from the radiator thermostat and keep the left and right button pressed when inserting the batteries.
      • Then click on the Update button in the WebUI as quickly as possible (Settings - Devices - Radiator Thermostat: Set). This process may take several minutes.
      • "FUP" is shown on the radiator thermostat display.
      • The "Firmware update successful" message is displayed in the WebUI.
      • The radiator thermostat is restarted and behaves in the same way as after a change of battery.
