AND
MODE
In the heating mode, you can heat the room in spring or fall. The desired
room temperature is set with the ▲/▼ buttons in 1 °C increments. If the
room temperature is 1 °C below the selected target temperature, the in-
door unit starts to heat the air in the room. The inverter controller checks
the difference between the adjusted target 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 tempera-
ture.
If the adjusted room temperature is still exceeded by approx. 2 °C, then
the control system turns the heating function off. To protect the com-
pressor, the regulation only turns the heater on again after a waiting
period of 3 minutes.
In heating mode, the indoor unit fan motor is switched on after a delay,
in order to prevent the discharge of cold air.
The fins on the outdoor unit could crack at low outdoor temperatures.
Regular reversal of the cooling circuit results in a defrosting action. The
display shows "H1" during the defrosting period.
