Establishing radio connection
The radiator controller HR92 communicates with the
central operating device by radio using the frequency
of 868 MHz. To this purpose the connection between
the HR92 and the central operating device has to be
established first. This process is called BINDING. In the
case of preconfigured devices binding has already been
carried out in the factory.
iIf binding has not yet been carried out, unbound is
displayed after has been pressed.
Binding must first be activated at the HR92 so that the
radio signal can be received. Subsequently binding has
to be activated at the central operating device.
iPlease read the operating instructions of your central
operating device for further information about binding.

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 and press the button.
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 off
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).
fPress button.
The room name (zone name) is shown briefly in the
display.

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
turning the adjustment dial.
The sensitivity of the radiator controller to a temperature
drop or temperature rise can be set, see Section 5,
Parameters 3 to 5.
If a window contact is connected, the window function
reacts directly to the opening and closing of the window,
see Parameter 11.
Valve protection
If the radiator valve has not been opened once
completely within the period of 2 weeks, a self-test
(forced operation) 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 system
from freezing up.
