11-7. 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 (approx. 12V) transmitted from indoor microprocessor.

(2)The horizontal vane angle and mode change as follows by pressing VANE CONTROL button.

MSY-A15/17

MSZ-A24

MSY-A24

(3)Positioning

The vane is once pressed to the vane stopper to confirm the standard position and then set to the desired 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.

(c)When multi-standby starts or finishes.

(4)VANE AUTO ( ) mode

In VANE AUTO mode, the microprocessor automatically determines the vane angle and operation to make the optimum room-temperature distribution.

(1)In COOL and DRY operation

Vane angle is fixed to Horizontal position or Angle 1.

 

Upward

(2) In HEAT operation (MSZ)

Vane angle is fixed to Angle 4.

 

(5)STOP (operation OFF) and ON-TIMER standby

In the following cases, the horizontal vane returns to the closed position.

(a)When OPERATE/STOP (ON/OFF) 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 2 ~ 4 (A09 ~ 17) / Angle 3 ~ 5 (A24) when the compressor cumulative operation time exceeds 1 hour, the vane angle automatically changes to Angle 1 for dew prevention.

(7)SWING MODE ( )

By selecting SWING mode with VANE CONTROL button, the horizontal vane swings vertically. The remote controller

displays “ ”.

(8)Cold air prevention in HEAT operation (MSZ) The horizontal vane position is set to Upward.

NOTE: When 2 or more indoor units are operated with multi outdoor unit, even if any indoor unit turns thermostat off, this control doesn’t work in the indoor unit.
