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

nominal 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, then the indoor unit starts

to cool down the air in the room. The inverter controller checks the

difference between the adjusted nominal temperature and the actual

room temperature. In the event of a greater difference, a higher cooling

performance is created. In the event of a smaller difference, a lower

cooling performance is created. 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

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

evaporator, 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 switched on and off in intervals.
