13.2.7 Airflow direction
• There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by
vertical vanes).
• Control of airflow direction can be automatic (angles off direction is determined by operation mode, heat
exchanger temperature and intake air temperature) and manual (angles of direction can be adjusted using
remote control).

• 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.
• 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.
