Fan operation
Airflow can be switched in 5 steps such as AUTO, QUIET, LOW, MED, HIGH while indoor unit fan
only runs.
When fan mode is set at AUTO, it operates on MED fan speed.
Cooling operation
Switch the airflow AUTO, and indoor fan motor will run according to room temperature, as below.
On the other hand, if switched in HIGH—QUIET, indoor motor will run at a constant airflow of COOL
operation modes QUIET, LOW, MED, HIGH as shown in “Fan speed” above.

Dry operation
During dry operation, fan speed setting can not be changed as shown in “Fan speed” above.
Heating operation
Switch the airflow AUTO, and the indoor fan motor will run according to a room temperature, as be-
low.
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 “Fan speed” above.

Cool air prevention control (heating mode)
The maximum value of the indoor fan speed is set as shown below, based on the detected tempera-
ture by the indoor heat exchanger sensor on heating mode.
