In cooling mode, the air in the room is cooled down to the set target

temperature. The desired room temperature is set with the

/buttons

in 1 °C increments. If the room temperature is 1 °C above the selected

nominal temperature, the indoor unit starts to cool the air in the room.

The inverter controller checks the difference between the adjusted

target temperature and the actual room temperature. If there is a large

difference, the cooling output is very high. If the difference is smaller,

a lower cooling output is produced. This serves to maintain the air

discharge temperature and the room temperature.

If the adjusted room temperature is lower than approx. 2 °C, then the

control system turns the cooling function off. To protect the compressor,

the regulation only turns the cooling on again after a waiting period of 3

minutes.

In dehumidification mode, the room temperature is set to 24 °C. Due

to the low temperature of the refrigerant, the dew point of the air on

the vaporiser is lower. The excess moisture in the air is condensed by

the vaporiser, the room is dehumidified. The fan speed should be set to

automatic in order to achieve a maximum level of dehumidification. In

automatic mode, the fan is intermittently switched on and off.
