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.
10.1.2.2. Horizontal Airflow
1. Automatic horizontal airflow direction can be set using remote control; the vane swings left and right within the angles as stated
below. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1
below.
Operation Mode Vane Angle (°)
Heating, with heat exchanger temperature A 68 ~ 112
B 90
Cooling, Soft Dry 68 ~ 112
2. Manual horizontal airflow direction can be set using remote control; the angles of the vane are as stated below and the positions
of the vane are as Figure 2 above.
