7. OPERATION DESCRIPTION

FILE NO. SVM-02005(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

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 microcontroller, 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.

7-2. Description of Operation Circuit

(1) When turning on the breaker, the operation lamp

blinks. This means that the power is on (or the power supply is cut off.)

(2) When pressing [START / STOP] button on the

remote control, receiving beep sounds from the indoor unit, and the next operation is performed together with opening the vertical air flow louver.

(3) Once the operation mode is set, it is memorized in

the microcontroller so that the previous operation can be effected thereafter simply by pressing [START / STOP] button.

7-2-1. Fan only operation

([MODE] button on the remote control is set to the fan only operation.)

(1) When [FAN] button is set to AUTO, the indoor fan

motor operates as shown in Fig. 7-2-1. When [FAN] button is set to LOW, LOW+, MED, MED+ or HIGH, the motor operates with a constant air flow.

(2) The microcontroller turns the compressor on and

off at the regular intervals (4 to 6 minutes). While the compressor is turning off, the indoor fan motor operates in the SUPER LOW position.

The pattern of operation depending on the relation

between room temperature and preset temperatures is shown in Fig. 7-2-5.

7-2-4. Automatic operation

([MODE] button on the remote control is set to the automatic operation.)

(1) One of 2 operations (Cooling, Fan only) is

selected according to difference between the preset temperature and the room temperature at which the automatic operation has started, as shown in Fig. 7-2-6. The Fan only operation continues until the room temperature reaches a level at which another mode is selected.

(2) Temporary Auto

When the TEMPORARY button on the indoor unit is pushed, the preset temperature is fixed at 24°C and the indoor unit is controlled as shown in Fig. 7-2-6.

7-3. Hi POWER Mode

([Hi POWER] button on the remote control is pressed.)

When [Hi POWER] button is pressed while the indoor unit is in Auto, Cooling, Hi POWER mark is indicated on the display of the remote control and the unit operates as follows.

(1) Automatic operation

• The indoor unit operates in according to the current operation.

(2) Cooling operation

• The preset temperature drops 3°C. (The value of the preset temperature on the remote control does not change.)

• If the difference between the preset temperature and the room temperature is big, the horizontal louver moves to the Hi POWER position automatically. Then when the difference between them gets smaller, the horizontal louver returns automatically.

• FAN speed : [AUTO] If the difference between the preset temperature and room temperature is big, the air conditioner operates at maximum airflow level. If the difference between the preset temperature and the room temperature is small, the air conditioner operates at normal airflow level.

• FAN speed : One of 5 levels The air conditioner operates at normal airflow level.

(3) The Hi POWER mode can not be set in Dry or Fan

only operation.

7-4. High-Temperature Limit Control

The microcontroller detects the indoor heat exchanger temperature to prevent pressure of a refrigerating cycle from increasing excessively. The compressor and outdoor fan motor are controlled as shown in Fig. 7-4-1.

7-5. Low-Temperature Limit Contr ol

The microcontroller detects the indoor heat exchanger temperature to prevent the indoor heat exchanger from freezing. The compressor and outdoor fan motor are controlled as shown in Fig. 7-5-1 and 7-5-2.
