Installation
5.1.3 Support ring
The valves from dierent manufacturers may have tolerance fluctua-
tions that make the radiator thermostat more loosely seated on the
valve. In this case, the provided support ring (Q) should be placed into
the flange before mounting the radiator thermostat (see figure 5).
5.2 Adaption run
Once the batteries have been inserted, the motor reserves.
Meanwhile, “InS” and the activity symbol ( ) are displayed.
After the radiator thermostat has been mounted successfully, an
adaption run (AdA) has to be performed in order to adapt the device
to the valve:
• As soon as “AdA” is displayed, press the menu/boost button (G) to
start the adaption run.
It is now that the radiator thermostat performs an adapting run. “AdA”
and the activity symbol ( ) are displayed. Wait until the adaption run is
completed. Afterwards, the display returns back to normal.
If the adapter run has been initiated prior to mounting or if
an error message (F1, F2, F3) is displayed, press the menu/
boost button (G) and the motor reverses to the “InS”
position.
