Description of the parameters
Parameter 2 – Backlight
The display has a backlight for reading the information.
• The backlight is ON when the adjustment dial is
turned or a button is pressed.
• The backlight switches OFF if no action is carried
out at the radiator controller for approx. 7 seconds in
order to save battery power.
Parameters 3 to 5 – Window function
In order to save energy the radiator controller closes the
radiator valve when you open a window resulting in a
large drop of the temperature.
When you close the window so that the temperature
rises the radiator controller opens the radiator valve
again.
When the duration of the window function (factory
setting: 30 minutes) has expired, the system controls
to the current room setpoint temperature again. Frost
protection is ensured during the window function.
Parameter 6 – Valve stroke
The radiator controller operates with the optimum valve
stroke set in the factory.
If the entire valve stroke is to be used or if the valve does
not open completely, activate the full-stroke mode.
Parameter 7 – Temperature representation in the
display
• In the factory setting the room setpoint temperature
is displayed.
• With the setting "measured temperature" the
measured room temperature is displayed. A
changeover to the set temperature is carried out by
turning the adjustment dial or pressing the button.
If required, the temperature can now be reset. The
display returns to the measured temperature after
approx. 3 seconds.
Due to the heat influence of the radiator the
"measured temperature" displayed at the radiator
controller can differ from the temperature measured
at another point in the room.
Parameter 8 – 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
21.0 °C at the radiator, this effect can be compensated
by an offset of –1.0 °C.
Parameter 10 – Display of the valve position
When this parameter is activated (setting "1"), the
calculated valve position (0 ... 100% opened) is
displayed momentarily.
The main display is shown again after approx. 3 minutes.
To cancel, select
exit
Parameter 11 – Window open function
• If a window contact is connected, the parameter is set
automatically to "2" (cabled). The window function is
controlled by the window contact.
• If no window contact is connected, the setting "0" or
"1" has to be selected.
6. Further functions
Manual changing of the room setpoint
temperature
The room setpoint temperature can be changed at any
time by means of the adjustment dial. The changed room
setpoint temperature remains in effect until the next
switching point.
The symbol
shows that the temperature was
changed manually. The symbol extinguishes when the
next setpoint is reached.
By turning the adjustment dial anti-clockwise until
is displayed, the valve will be closed permanently.
With this setting the time program of the central
operating device is no longer active for this radiator
controller, but frost protection is guaranteed if the
heating is switched on.
Display of the room name
If the central operating device can transmit the room
name (zone name), like the evotouch, the room
name is displayed at the radiator controller (max. of
9 characters).
