NOTE:

•If you make the airflow not to blow directly onto your body by pressing VANE CONTROL button, the compressor stops for 3 minutes even during the operation of the air conditioner.

•The air conditioner operates with Very Low speed until the compressor turns on again.

(10)ECONO COOL ( ) operation (ECONOmical operation)

When ECONO COOL button is pressed in COOL mode, set temperature is automatically set 3.6°F higher than that in COOL mode.

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 than that in COOL mode, the air conditioner can keep comfort. As a result, energy can be saved.

ECONO COOL operation is cancelled when ECONO COOL button is pressed once again or VANE CONTROL button is pressed or change to other operation mode.

(11) POWERFUL ( ) operation

The air conditioner automatically adjusts the fan speed and the set temperature, and operates the POWERFUL mode.The POWERFUL mode is automatically released 15 minutes after operation starts, and the operation mode returns to the mode prior to POWERFUL operation.

2.Vertical vane (MSZ-A24, MSY-A24)

(1)Vane motor drive

These models are equipped with a stepping motor for the vertical vane. The rotating direction, speed, and angle of the motor are controlled by pulse signals (approx. 12V) transmitted from microprocessor.

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

(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 OPERATE/STOP(ON/OFF) button is pressed (POWER ON/OFF).

(b)When SWING is started or finished.

(c)When the power supply turns ON.

(4)SWING MODE ( )

By selecting SWING mode with WIDE VANE button, the vertical vane swings horizontally. The remote controller displays “ .”
