(5) STOP (operation OFF) and ON TIMER standby
In the following cases, the horizontal vane returns to the closed position.
(a) When OFF/ON (stop/operate) button is pressed (POWER OFF).
(b) When the operation is stopped by the emergency operation.
(c) When ON TIMER is ON standby.
(6) Dew prevention
If the lower position is selected during COOL/DRY, the vane automatically moves to the upward position after 0.5 to 1
hour to prevent any condensation from dripping.
9-6. AUTO VANE OPERATION
1. Horizontal vane
(1) Vane motor drive
These models are equipped with a stepping motor for the horizontal vane. The rotating direction, speed, and angle of
the motor are controlled by pulse signals (approximately 12 V) transmitted from indoor microprocessor.
(2) The horizontal vane angle and mode change as follows by pressing VANE control button.
(AUTO)

(2)
(3)
(4)
(5) (SWING)
(3) Positioning
To confirm the standard position, the vane moves until it touches the vane stopper. Then the vane is set to the
selected angle.
Confirmation of standard position is performed in the following cases:
(a) When the operation starts or finishes (including timer operation).
(b) When the test run starts.
(c) When standby mode (only during multi system operation) starts or finishes.
(4) VANE AUTO (
) mode
In VANE AUTO mode, the microprocessor automatically determines the vane angle to make the optimum room tem
-
perature distribution.
Horizontal
position
In COOL and DRY operation
Vane angle is fixed to Horizontal position.
In HEAT operation
Vane angle is fixed to Downward position.
(7) SWING (
) mode
By selecting SWING mode with VANE control button, the horizontal vane swings vertically.
(8) ECONO COOL ( ) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, set temperature and the air flow direction is automati-
cally changed by the microprocessor. However, the temperature on the LCD screen on the remote controller is not
changed. Also the horizontal vane swings in various cycle.
SWING operation makes you feel cooler than set temperature. So, even though the set temperature is higher, the air
conditioner can keep comfort. As a result, energy can be saved.
To cancel this operation, select a different mode or press one of the following buttons in ECONO COOL operation:
ECONO COOL, VANE control or POWERFUL button.
(10)
POWERFUL (
) operation
The air conditioner automatically adjusts the fan speed and the set temperature, and operates the POWERFUL mode.
The POWERFUL mode is cancelled automatically 15 minutes after operation starts, or when POWERFUL button
is pressed once again within 15 minutes after operation starts. The operation mode returns to the mode prior to
POWERFUL operation. To cancel this operation manually, select a different mode or press one of the following but
-
tons within 15 minutes after operation starts: STOP/OPERATE (OFF/ON), ECONO COOL,
FAN SPEED CONTROL,
CIRCULATOR, or i-save button.
