If the outdoor air temperature is high, it can take some time until the indoor room
temperature reaches the setpoint temperature.
When the indoor room temperature is low, and the indoor unit is set to run in
Cooling operation mode, the indoor unit can enter Defrost operation mode first
(i.e. Heating operation), this to prevent a decrease of the system's cooling capacity
due to frost on the heat exchanger. For more information, see "Heating" [
The indoor unit can run in Cooling operation mode because it is operating under
Setback conditions. For more information, see "Setback" [
When running in Heating operation mode, the system requires a longer time to
reach the setpoint temperature than when running in Cooling operation mode. To
make up for this, it is recommended to let the system start operation in advance by
making use of the timer function.
The indoor unit can run in Heating operation mode because it is operating under

can run in the following special heating operation modes:
