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).

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.
