2.5 Cooling Breeze Operation
Operation
 Effective mode for cooling breeze airflow
• Auto / Cooling
• QUATERNITY drying
• Dry cooling
• Flash streamer air purifying
Note In automatic mode, when actual operation mode is heating, this cool air fluctuation operation does
not work. (Indication on remote controller is shown.)
 Fin operation
As shown in the following graph, the standard point is the upper limit of the swing so that the air
does not touch directly.
Depending on the room temperature or the thermostat on/off state, the swing interval is
changed.
The lower the temperature, the longer the swing interval, thereby comfort is maintained.Left
and right fins move as set on the remote controller.
 Airflow rate
Airflow rate is controlled automatically.
∗ Refer to the operation manual for details.
Features  1/f fluctuation rhythms switches airflow direction
By fluctuating airflow direction you can feel cool even if the room temperature is set high.
By1/f fluctuation rhythm, upper and lower louvers move up and down unlike the conventional up
and down swing, and this movement brings you comfortable air like breezes in nature.
