1.5 COANDA Operation
Outline
The horizontal flap is controlled not to blow the air directly at the people in the room.
If you press
SWING
button during COANDA operation, COANDA operation will be canceled.
The airflow rate can be set to any level. However, a low airflow rate may cause cold air to go
down and blow on people.
Details
When POWERFUL operation is started during COANDA operation, the flap turns downward,
allowing the air to blow directly onto people. The combination of COANDA and POWERFUL
operations provides sufficient cooling (heating) performance to quickly cool down (warm up)
the room. After POWERFUL operation is finished, the system automatically returns to
COANDA operation.
When COANDA operation is started during POWERFUL operation, the system prevents the
air from blowing directly onto people while keeping POWERFUL operation.
