The maximum value of the indoor fan speed is set as shown in Fig. 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 below.
On the other hand, if switched in [Hi] ~ [Quiet], the indoor motor will run at a constant airflow
of [Heat] operation modes Quiet, Lo, Me, Hi, as the previous page.
