Automatic vertical airflow direction can be set using remote control; the vane swings up and down within theangles as stated above. For heating mode operation, the angle of the vane depands on the indoor heatexchanger temperature as Figure 1 below. It does not swing during fan motor stop. When the air conditioner isstopped 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 andthe positions of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, thevane will shift to close position.58°C50°CIndoor HeatExchanger Temperature36°C30°CCAFigure 1BFigure 2Upper vane: 60°Lower vane: 58°Reference pointClosed PositionStep 1Step 2Step 3Step 4Step 512.4.2 Horizontal Airflow• The horizontal airflow direction louvers can be adjusted manually by hand.12.5 Quiet operation (Cooling Mode/Cooling area of Dry Mode)A. PurposeTo provide quiet cooling operation compare to normal operation.B. Control conditiona. Quiet operation start condition• When “Quiet” button at remote control is pressed.Quiet LED illuminates.b. Quiet operation stop condition1. When one of the following conditions is satisfied, quiet operation stops:a. Powerful button is pressed.b. Stop by OFF/ON switch.c. Timer “off” activates.d. Quiet button is pressed again.2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode.5. During quiet operation, if timer “on” activates, quiet operation maintains.6. After off, when on back, quiet operation is not memorised.
