The maximum value of the indoor fan speed is set as shown in Figure5, based on the detected
temperature by the indoor heat exchanger sensor on heating mode.

5. HEATING OPERATION
Switch the airflow [AUTO], and the indoor fan motor will run according to a room temperature,
as shown in Figure4.
On the other hand, if switched in [HIGH] [QUIET], the indoor motor will run at a constant airflow
of [HEAT] operation modes QUIET, LOW, MED, HIGH, as shown in Table4.
