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 Airflow1.
