7. OPERATION DESCRIPTION

7-1-1. Louver control

(1)Vertical air flow louver

Position of veritcal air flow louver is automatically controlled according to the operation mode. Besides, position of vertical air flow louver can be arbitrarily set by pressing [FIX] button. The louver position which is set by [FIX] button is stored in the microcomputer, and the louver is automatically set at the stored position for the next operation.

(2)Swing

If [SWING] button is pressed when the indoor unit is in operation, the vertical air flow louver starts swinging. When [FIX] button is pressed, it stops swinging.

7-1-2. Indoor fan control (AC Fan motor)

(1)The indoor fan is operated by the stepless speed

change AC motor.

(2)For air flow level, speed of the indoor fan motor is

controlled in five steps (LOW, LOW

, MED, MED

and HIGH). If AUTO mode is selected, the fan motor speed is automatically controlled by the difference between the preset temperature and the room temperature.

Table 7-1-1

7-1. Outline of Air Conditioner Control

This is a fixed capacity type air conditioner, which uses a AC motor for an indoor fan. The AC motor drive circuit is mounted in the indoor unit. And electrical parts which operate the compressor and the outdoor fan motor, are mounted in the outdoor unit. The air conditioner is mainly controlled by the indoor unit controller. The controller operates the indoor fan motor based upon commands transmitted by the remote control and transfers the operation commands to the outdoor unit controller. The outdoor unit controller receives operation commands from the indoor unit, and operates the outdoor fan motor and the compressor.

(1) Role of indoor unit controller

The indoor unit controller receives the operation commands from the remote control and executes them.

• Temperature measurement at the air inlet of the indoor heat exchanger by the indoor temperature sensor

• Temperature setting of the indoor heat exchanger by the heat exchanger sensor

• Louver motor control

• Indoor fan motor operation control

• LED display control

• Transferring of operation commands to the

outdoor unit

• Receiving of information of the operation status and judging of the information or indication of error
