Parameter 13 – temperature offset
Since the radiator controller measures the room
temperature in the area of the radiator, it is possible
that this temperature deviates from the temperature
measured at a different point in the room.
If, for example, 20 °C is measured in the room and at the
radiator 21.5 °C, this effect can be compensated by an
offset of –1.5 °C. The display at the radiator controller
remains unchanged.
Parameter 15 – Display of the valve position
When this parameter is activated (setting "1"), the
calculated valve position is displayed (0 to 100%
opened) briefly.
The main display is shown again after approx. 3 minutes
or when the
AUTO
button is pressed.
Changing parameters
1. Keep the
PROG
button pressed for at least
10 seconds until Parameter 1 flashes (left-hand digit).
The right-hand digit shows the current setting.
The parameter is displayed additionally in plain text.
For example, the display
1 1
stands for Parameter 1
(language) with Setting 1 (German).
2. If desired, use the adjustment dial to select a different
parameter (left-hand digit).
3. Press the
OK
button to edit the parameter.
The current setting of the parameter flashes (right
hand digit).

6. For the further parameters repeat Steps 2 to 4.
7. Use the
AUTO
button to return to automatic mode.

Monitoring functions
Window function
If you open a window causing the temperature to drop,
the radiator controller closes the radiator valve in order
to save energy.
window
is displayed.
When the temperature rises again, but at the latest after
the set period (factory setting: 30 minutes), the radiator
controller opens the radiator valve again.
You can also open the radiator valve beforehand by
pressing the
AUTO
button or turning the adjustment
dial.
The sensitivity of the radiator controller to a temperature
drop or temperature rise can be set, see Section 9,
Parameters 5 to 7.
Valve protection
If the radiator valve has not been opened completely for
2 weeks, a self test is carried out. The radiator controller
opens the radiator valve briefly on the subsequent
Monday in order to prevent seizing.

Frost protection
If the temperature drops below 5 °C, the radiator
controller opens the radiator valve until the temperature
rises above 6 °C again. This prevents the heating from
freezing up.

The heating may not be switched off. Otherwise the
radiator controller cannot carry out the frost protec-
tion function.
Summer break
If you have switched off the central heating system
in summer and do not want to waste the batteries of
the radiator controller, you can close the radiator valve
continuously.
Closing the valve
1. Press the button
