Description
Automatic
The system cools down or heats up a
room to the temperature setpoint. It
automatically switches between cooling
and heating if necessary.
Drying
The system decreases the humidity in a
room.
Heating
The system heats up a room to the
temperature setpoint.
Cooling
The system cools down a room to the
temperature setpoint.
Fan
The system only controls the airflow
(airflow rate and airflow direction).
The system does NOT control the
temperature.
Additional info:
▪
Outside temperature.
The system's cooling or heating effect
decreases when the outside temperature is too high or too low.
▪
Defrost operation.
During heating operation, frost might occur on
the outdoor unit and decrease the heating capacity. In that case,
the system automatically switches to defrosting operation to
remove the frost. During defrosting operation, hot air is NOT
blown from the indoor unit.
