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. It does not swing during fan motor stop. 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.
3. If automatic control ( ) or automatic swing ( ) vane is selected, the inputs of the control are: mode of operation,
inlet temperature, and heat exchanger temperature.
4. If manual vane is selected, the inputs are: Up-and-down vane actual signal.
