The image 14 is an example of a heating curve for a
conventional radiator and displays the temperatures that are to
be set in this section.
Parallel displacement of the heating curve corresponding
to the deviations of the room temperature
Deviations of the room temperature from the set height are
compensated for by means of a parallel displacement of the
heating curve. The higher the setting value, the greater the
weighting of the room temperature deviation and the maximum
possible influence of the room temperature on the heating
curve.

7.1 outside temperature sensor or new control unit
Control unit and Key are connected in delivered condition
ex factory and detect each other automatically when
powered up. An optionally available wireless outside
temperature sensor must be connected to the Key.
If another/additional wireless participant is to be connected to
the Key, the Key must be in the pairing mode:
▶ Briefly press key on Key.
The LED flashes yellow. Pairing mode is activated.
▶ During this time, transfer the new wireless participant
(control unit or wireless outside temperature sensor)
in pairing mode too.
If the pairing is successful, the LED 5 flashes green for seconds.
If the pairing is not successful, i.e. no new wireless participant
was connected, the LED 5 flashes red for seconds.
