modes.
Fig. 5: Operating diagram of the operating modes
1. Cooling mode:
In cooling mode, the air in the room is cooled to
the set target temperature. If the room temperature
is above the desired temperature, the indoor unit
starts to cool the air in the room. If the temperature
falls to approx. 0.5 °C below the set room tempera-
ture, the regulation will switch off cooling mode.
We recommend setting the target temperature to
max. 6 °C below the outside temperature.
2. Dehumidification mode:
In Dehumidification mode, the setpoint tempera-
ture and the fin position can be set. It is not pos-
sible 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.
3. Heating mode:
In heating mode, the room air is heated to the pre-
determined setpoint. If the room temperature is
below the desired temperature, the indoor unit
starts to heat the room air. The fan only starts up
once the fin temperature has reached 38 °C. If the
actual temperature rises above the set room tem-
perature, the regulation switches the valve off. If
the fin temperature falls below 38°C, the fan
switches off.
4. Circulated air 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. This mode
allows the heat trapped under the ceiling to be cir-
culated to the lower regions of the room in winter.
When selecting the operating mode, make sure
that all indoor units connected to an outdoor
unit are operated either in Heating mode or in
Cooling and Dehumidification modes so that no
mode conflicts occur. Recirculation mode can
always be selected independently of the other
indoor units.
