Fig. 2: Keys on the remote control
The remote control is operated using the relevant
keys on the touchpad.
1
"ON/OFF" key
This key switches the indoor unit on and off.
2
"Flap setting/swing function” key
The air discharge fins can be moved into the
desired position by pressing this key. You can acti-
vate the swing mode by holding this key down.
3
"Confirm/quiet mode" key
If this key is pressed in cooling mode, heating
mode or recirculation mode, the unit switches to
quiet operating mode. To achieve this, the fan
speed is reduced to a minimum. In automatic and
drying mode, the fan speed is set automatically
and this key is redundant.
4
"Increase temperature" key
Pressing this key increases the setpoint in 1 °C
steps.
5
"Lower temperature" key
Pressing this key lowers the setpoint in 1 °C steps.
6
"Timer" key
The delayed turn on and turn off time can be pro-
grammed with this key.
7
"Mode" key
Press this key to choose from the different oper-
ating modes:
1. Automatic mode:
In automatic mode, the controller automatically
selects either heating or cooling mode, depending
on the set target temperature. Provided an ade-
quate heating medium or coolant with a sufficient
temperature is available, it is possible to guarantee
a constant room temperature. The fan speed
should be set to automatic.
2. Cooling mode:
In cooling mode, the air in the room is cooled to
the set target temperature. Press the TEMP key to
set the desired room temperature in 1 °C steps. If
the room temperature is 1 °C above the desired
temperature and sufficient coolant is available, the
indoor unit will start to cool the room air. If the
actual temperature falls approx. 0.5 °C below the
set room temperature, the controller switches the
cooling function off. Please always observe the fol-
lowing additional information: We recommend set-
ting the target temperature to max. 6°C below the
outside temperature. The automatic fan speed and
swing functions should also be used.
3. Dehumidification mode:
After selecting dehumidification mode with the
MODE key, the desired temperature and fin posi-
tion can be selected. It is not possible to set the
fan speed. The fan is switched off at certain inter-
vals to lower the fin temperature. The cooling reg-
ister cools the air below its dew-point due to the
low medium temperature - this results in the air-
borne humidity being condensed out. This reduces
the moisture content of the room air.
4. Heating mode:
In heating mode, the room air is heated to the pre-
determined setpoint. Press the TEMP key to set
the desired room temperature in 1 °C steps. If the
room temperature is below the set target tempera-
ture, the valve provided by the customer opens. If
there is sufficient heating medium available, the
indoor unit starts to warm up the air in the room.
The fan only starts up once the fin temperature has
reached 38°C. If the actual temperature rises
approx. 1 °C above the set room temperature, the
controller switches the valve off. If the fin tempera-
ture falls below 38°C, the fan switches off. Please
always observe the following additional informa-
tion: We recommend setting the target temperature
to max. 28°C. Maximum fan speed and the lowest
fin setting should also be used.

5. Recirculation mode:
In this mode, the unit is used as an air circulation
unit. It is not possible to set a target temperature.
The room is neither heated nor cooled. Please
always observe the following additional informa-
tion: This mode allows the heat trapped under the
ceiling to be circulated to the lower regions of the
room in winter.
