4. DRY OPERATION
Refer to the Table 6.
During the dry mode operation, the fan speed setting can not be changed.
5. HEATING OPERATION
Switch the airflow [AUTO], and the indoor fan motor will run according to a room temperature,
as shown in Figure 7.
On the other hand, if switched in [HIGH]
of [HEAT] operation modes QUIET, LOW, MED, HIGH, as shown in Table 6.

6. COOL AIR PREVENTION CONTROL (Heating mode)
The maximum value of the indoor fan speed is set as shown in Figure 8, based on the detected
temperature by the indoor heat exchanger sensor on heating mode.
