Available in COOL operation with fan speed on HIGH or in HEAT operation.

Unavailable in DRY operation.

If fan speed changes from LOW to HIGH during 30° downward discharge in COOL mode, the direction auto- matically changes to 10°.

(1) COOL/DRY operation

At the start-up of COOL or DRY operation, the discharge direction in automatically set to 10°. After, it can be changed to

another direction with VANE ( ) button on the remote controller.

<Auto return>

When discharge 60° or 70° continues for 1 hour with the fan speed at LOW, the discharge direction turns to the horizontal discharge automatically.

After that, 60° or 70° is available by setting with the remote controller, and it continues for 1 hour.

If the discharge direction changes from 60° or 70°, the direction returns to the horizontal discharge when 1 hour has passed since the discharge 60° started.

If the discharge direction changes from 60° (or 70°) to the horizontal discharge, the 1-hour timer to return the horizontal discharge is cancelled.

(2) HEAT operation

At the start-up of HEAT operation, discharge direction depends on the setting of the last operation.

After, it can be changed to another direction with VANE ( ) button. The discharge direction shifts to 10° regardless of the remote controller settings under any of the following conditions.
