Using the FRITZ!DECT radiator control in the FRITZ!Box home network

FRITZ!DECT radiator controls, for example FRITZ!DECT 301, are integrated into the FRITZ!Box home network via an encrypted DECT connection (DECT ULE). You can then use the FRITZ!Box user interface to set up an individual heating program and also operate the thermostat over the internet when you are away from home.

Requirements / Restrictions

  • The radiator control is mounted on the radiator valve and has been adapted. You can find information on mounting and adapting it in the manual.
  • A maximum of twelve radiator controls can be registered with the FRITZ!Box.

1 Establishing a DECT connection

  1. Push the "DECT" button on your FRITZ!Box. Hold down the button for at least 6 seconds until the "DECT" or "Info" LED on the FRITZ!Box begins to flash. The FRITZ!Box is in registration mode as long as the LED flashes.
  2. Push the "MENU" button on the radiator control within 2 minutes.
  3. Select the menu item "FUNK" or "Anmeldung" on the radiator control and then push the "OK" button.
    • The message "Login was successful" is shown in the display of FRITZ!DECT 301.
  4. If you have a FRITZ!DECT 300 or Comet DECT, wait until "SUCH" flashes in the display and then push the "OK" button.

The DECT connection is established as soon as the "Radio link" symbol in the display of the radiator control lights up continuously.

2 Setting up the radiator control

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Smart Home" in the "Home Network" menu.
  3. If available, select the option "All smart home devices" in the drop-down list "viewing".
  4. Click the button (Edit) for the respective device.
  5. Configure the desired settings.
  6. Enable the option "Push service enabled" so that you receive an email if the battery is low, the radio connection is lost, or there are errors in the radiator control.

    Note:This guide contains information on setting up the push service.

  7. Click "OK" to save the settings.

Since radiator controls function according to the DECT ULE (Ultra Low Energy) standard, they communicate with the FRITZ!Box at greater intervals to save energy and minimize DECT radiation. As a result, it may take up to 15 minutes for the settings to be transferred to the radiator control. It may even take up to 60 minutes during vacation switching and the phase when the radiator is turned off. By pushing any button on the radiator control, you can cause the settings to be transmitted immediately.
