The maximum value of the indoor fan speed is set as shown in Fig.6 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 Fig. 5
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, High, as shown in Table 6.
