11.4 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 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).

Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the
angles as stated above. 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 below. When the air conditioner is stopped using remote control, the vane
will shift to close position.
11.4.2 Horizontal Airflow
The horizontal airflow direction louvers can be adjusted manually by hand.
11.5 Timer Control
11.5.1 ON Timer Control
ON timer can be set using remote control, where the unit with timer set will start operation earlier than the setting
time. This is to provide a comfortable environment when reaching the set ON time.
60 minutes before the set ON time, indoor (at fan speed of Lo-) and outdoor fan motor start operation for 30 seconds
to determine the indoor intake air temperature and outdoor air temperature in order to judge the operation starting
time.
From the above judgment, the decided operation will start operation earlier than the set time as shown below.
