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 following information:
We recommend setting the target temperature to max. 6°C below the
outside temperature.
After selecting dehumidification mode with the MODE key, the
desired temperature and fin position can be selected. It is not possible
to set the fan speed. The fan is switched off at certain intervals to
lower the fin temperature. The cooling register cools the air below its
dew-point due to the low medium temperature - this results in the
airborne humidity being condensed out. This reduces the moisture
content of the room air.
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 information:
This mode allows the heat trapped under the ceiling to be circulated
to the lower regions of the room in winter.
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
temperature, 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 temperature falls below 38°C, the fan switches off.
Please always observe the following information:
We recommend setting the target temperature to max. 28°C.
Maximum fan speed and the lowest fin setting should also be used.

Master and slave settings
A higher-level unit with cabled remote control (master) can control any additional
unit (slave) individually. From the master unit all or each individual slave unit can be
controlled. The cabled remote control is assigned an address with which the units can
be distinguished. The address is assigned by setting the corresponding DIP switches
on the back of the board. After the rear half of the remote control housing has been
detached, the switches are visible at the bottom right of the circuit board.
Dip switch
The master remote control must always
be assigned address 01. All switches
must be switched down.
Addresses 02 to 32 are assigned to the
slave remote controls. To define the
address, the DIP switches are set as
shown in the table.
