12.4 Airflow Direction
1. There is one type of airflow, vertical airflow (directed by horizontal vane).
2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat
exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using
remote control).

1.
Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated
above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1
below. When the air conditioner is stopped using remote control, the vane will shift to close position.
2.
Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions
of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close
position.
12.5 Quiet Operation (Cooling Mode/Cooling Area of Dry Mode)

Purpose
o
To provide quiet cooling operation compare to normal operation.

Control condition
o
Quiet operation start condition
 When “POWERFUL/QUIET” button at remote control is pressed twice.
POWERFUL/QUIET LED illuminates.
o
Quiet operation stop condition

When one of the following conditions is satisfied, quiet operation stops:

POWERFUL/QUIET button is pressed again.

Stop by OFF/ON switch.

Timer “off” activates.
 When quiet operation is stopped, operation is shifted to normal operation with previous setting.

When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
 When operation mode is changed, quiet operation is shifted to quiet operation of the new mode.
 During quiet operation, if timer “on” activates, quiet operation maintains.
 After off, when on back, quiet operation is not memorised.

Control contents
o
Fan speed is changed from normal setting to quiet setting of respective fan speed.
Fan speed for quiet operation is reduced from setting fan speed.
