3.2 Main functions
The remote control controls the product's
heating, cooling, ventilation and dehumidi-
fication functions.
The remote control has a time-scheduling
function for switching the indoor unit on
and off in a time-controlled manner.
3.2.1 Heating
The room temperature sensor measures
the room temperature. If the room temper-
ature is lower than the desired temperat-
ure, the control activates the heating.
In heating mode, the indoor unit increases
the temperature of the room in which it is
installed.
3.2.2 Cooling
The room temperature sensor measures
the room temperature. If the room temper-
ature is higher than the desired temperat-
ure, the control activates the cooling.

0020319945_00 Operating instructions 9
In cooling mode, the indoor unit reduces
the temperature of the room in which it is
installed.
3.2.3 Ventilation
In ventilation mode, the air is circulated in
the room.
It is not possible to set the temperature in
ventilation mode.
3.2.4 Dehumidification
In dehumidification mode, the indoor unit
reduces the air humidity in the room in
which it is installed.
It is not possible to set the fan speed in
dehumidification mode. The fan runs at
minimum rotational speed.
3.3 Permissible temperature

close blinds, etc.).
Noise emission During operation or when the unit is
switched off, you may hear a rustling
noise. The noise is at its loudest in the
first 2-3 minutes.
The cause of this rustling is the
refrigerant flowing into the unit.
The noise does not indicate that
there is a malfunction.
While the system is operating, a crack-
ling noise can be heard
The cause of this noise is temper-
ature changes and, linked to that,
the expansion or contraction of
the vessel. The noise does not in-
dicate that there is a malfunction.
A loud air noise while the system is op-
erating may be caused by contamina-
tion of the air filters
Clean the air filters thoroughly.
