Using the Software
NOTE
The control module switches to standby mode after 10 seconds: All LEDs are switched off.
To make settings: Press any key or rotate the knob.
Setting the room temperature
If you turn the knob, the function is activated:
Rotate the knob to the left: Reduce the temperature.
Rotate the knob to the right: Increase the temperature.
Depending on the selected temperature setting, the display of the LEDs changes.
Neither of the two LEDs is illuminated: The average value is set.
Blue LED illuminated: Increase by degrees (°C) to full intensity (-3°C in comparison to the
average value).
Red LED illuminated: Decrease by degrees (°C) to full intensity (+3°C in comparison to the
average value).
Energy saving mode
If you leave the room for a longer period of time, switch the presence button to “Absent”, LED
(OFF).
The energy saving function is activated and the temperature is set to a preconfigured value
(cannot be adjusted).
When you return to the room, switch the presence button to “Present”, LED (ON).
The energy saving function is switched off. You can adjust the temperature to a value of your
choice.
1 Knob Rotate: Set the value (e.g. temperature). Left: Lower it (blue LED).
Right: Raise it (red LED)
2 Presence button (power save button): Switch between “Present” and
“Absent”. Green LED (ON): “Present”
3 Fan in automatic mode: Fan speed specified by the controller. Green
LED (ON)
4 Reduce the speed, fan off. Four green LEDs: Max. to min. fan level
display
5 Fan on, increase speed. Four green LEDs: Min. to max. fan level dis-
play

CAN Address Setting
The address switch (1) is located on the PCB of the room control module (rear of device).
Address setting:
The address 1 is factory set and is automatically detected by RCN.
1 Address switch
Installation
Online installation via technolon® room controller RCN:
The technolon® room controller RCN can also be identified quickly and easily directly on the
room control module using a magnet (3). A magnet (3) is guided along the right side of room control
module RCN.
This triggers the service PIN in room controller RCN internally. This is indicated by a service
LED (4) on the top part of the housing on the room control modules that lights up green.
Notes for service technicians
Additional indicators
The red and blue LEDs on the knob remain illuminated: Field bus error (short circuit, interchanged
bus).
After interruption of the power supply, red and blue LEDs illuminate for approx. eight seconds until
the device is logged on.
The LED on the top part of the housing under the ventilation slots illuminates briefly once: When
logging onto the controller through the triggering of the dry reed contact on the external wall of the
housing (using magnets).
