Operation mode and temperature
setpoint
When. Adjust the system operation mode and set the temperature
when you want to:
▪ Heat up or cool down a room
▪ Blow air in a room without heating or cooling
▪ Decrease the humidity in a room
What. The system operates differently, depending on the user
selection.
Setting
The system cools down or heats up a
Automatic
room to the temperature setpoint. It
automatically switches between cooling
and heating if necessary.
The system decreases the humidity in a
Drying
room.
The system heats up a room to the
Heating
temperature setpoint.
The system cools down a room to the
Cooling
temperature setpoint.
The system only controls the airflow
Fan
(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.
