Using a FRITZ!DECT radiator control

Radiator controls, for example FRITZ!DECT 302, are integrated into the FRITZ! home network via an encrypted DECT connection (DECT ULE). Then you can use the FRITZ!Box user interface to set up an individual heating program.

Requirements / Restrictions

  • FRITZ!DECT 300 can only be used with FRITZ!Boxes equipped with DECT base stations, except for FRITZ!Box 7412.

1 Registering FRITZ!DECT radiator controls

  1. Click "Smart Home" in the FRITZ!Box user interface.
  2. Click "Device Management" in the "Smart Home" menu.
  3. Click the "Register Device" button.
  4. Within 2 minutes: Push the "MENU" button on the radiator control, select the menu item "FUNK", and then push the "OK" button. Wait until "SUCH" flashes in the display and then push the "OK" button.

The DECT connection is established as soon as the symbol for the radio connection is shown continuously in the display of the radiator control.

2 Installing FRITZ!DECT on the radiator and adjusting it to valve lift

The radiator control must first be mounted on the radiator and then adjusted to the valve lift of the radiator valve:

  1. Remove the thermostat from the radiator.
  2. If necessary, mount the appropriate adapter.
  3. Mount the radiator control.
  4. Push the "OK" button on the radiator control for about 3 seconds to adjust the radiator control to the valve lift. "ADAP" is shown on the display and the valve adjustment is successfully completed as soon as the temperature is shown on the display.

3 Setting up the radiator control

  1. Click "Smart Home" in the FRITZ!Box user interface.
  2. Click "Devices and Groups" or "Device Management" in the "Smart Home" menu.
  3. Click the (Edit) button for the respective radiator control.
  4. Configure the desired settings.
  5. 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.
  6. Click "Apply" or "OK" to save the settings.

To save energy and minimize DECT radiation, radiator controls only communicate with the FRITZ!Box at certain intervals. Therefore, it is possible that the changed settings may not be transmitted to the radiator control until after a maximum of 15 minutes. It takes up to 60 minutes during vacation switching and the phase when the radiator is turned off for them to be transmitted. To transmit the settings immediately, just push any button on the radiator control.

The radiator control is now configured and you can manually control the heater on the device itself, using the FRITZ!Box interface, with FRITZ!DECT 440, with FRITZ!Fon (menu "Home Network > Smart Home"), in the home network and over the internet with FRITZ!App Smart Home, or over the internet with MyFRITZ!App if you are using a FRITZ!Box with FRITZ!OS 7.1x or older.
