8-5. 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.

(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.
Confirming 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.
(4) VANE AUTO (
) mode
In VANE AUTO mode, the microprocessor automatically determines the vane angle to make the optimum room tem-
perature distribution.
Vane angle is fixed to Angle 1.
(8) ECONO COOL ( ) operation (ECONOmical operation)
When ECONO COOL button is pressed in COOL mode, the set temperature is automatically set 2°C higher.
Also the horizontal vane swings in various cycles.
SWING operation makes you feel cooler than the 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, LONG (
MS-CP18/24/30VA
) or POWERFUL button.
(9) POWERFUL COOL( ) operation
The air conditioner automatically adjusts the fan speed and the set temperature, and operates the POWERFUL COOL
mode.
The POWERFUL COOL mode is cancelled automatically 15 minutes after operation starts. To cancel this
operation manually, select a different mode or press one of the following buttons: POWERFUL COOL, OFF/ON (stop/
operate), ECONO COOL, or FAN speed control button.
(10) LONG MODE (
) (
MS-CP18/24/30VA
)
By pressing LONG button indoor fan speed becomes faster than setting fan speed on the remote controller, and the
horizontal vane moves to the position for LONG mode. The remote controller displays “
”. To cancel this opera-
tion, press one of the following buttons: LONG, VANE control, or ECONO COOL (during cool mode). In the following
example, the vertical vane is set to “
” (front.).
(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
During COOL or DRY operation with the vane angle at Angle 3 to 5 (
CP13
) 4 or 5 (
CP18/24/30VA
) when the com-
pressor cumulative operation time exceeds 1 hour, the vane angle automatically changes to Angle 2 for dew preven-
tion.
(7) SWING ( ) mode
By selecting SWING mode with VANE control button, the horizontal vane swings vertically.
