Operations according to the commands from the indoor unit

7-2. 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.

The outdoor unit 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 measurement 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

(2)Role of outdoor unit controller

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

∙ Compressor operation control

∙ Operation control of outdoor fan motor

∙Turning off the compressor and outdoor fan when the outdoor unit receives the shutdown command

FILE NO. SVM-10025

7-2-1. 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 [SWING] button is pressed, it stops swinging.

7-2-2. Indoor Fan Control

The operation controls the fan speed at indoor unit

side. The indoor fan (cross flow fan) is operated by the phase control induction motor. The fan rotates in 5

stages in MANUAL mode, and in 5 stages in AUTO mode, respectively. (Table 7-2-2)

1)When setting the fan speed to L, L+, M, M+ or H on the remote controller, the operation is performed with the constant speed shown in Table 7-2-1

Table (7-2-1)

Indication	Fan speed
L	Low
L+	(L + M) / 2
M	Med
M+	(M + H) / 2
H	High

2)When setting the fan speed to AUTO on the remote controller, revolution of the fan motor is controlled

to the fan speed level shown in Table 7-2-2 according to the setup temperature, room temperature, and heat exchanger temperature.

(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 [] 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 microcomputer so that the previous operation can be effected thereafter simply by pressing

[] button.

7-3-1. 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. 7-3-1. When [FAN] button is set to LOW, LOW+, MED, MED+ or HIGH, the motor operates with a constant air flow.

During the One Touch Comfort mode if the indoor unit receives any signal with other operation mode, the unit will cancel the comfort mode and operates according to the signal received.

Operation description.

When an indoor unit receives "One Touch Comfort Signal" from the remote controller, the indoor unit operates as following.

1)Air conditioner starts to operation when the signal is received, even if the air conditioner was OFF.

2)Operation mode is set Cooling mode.

3)Target temperature is 22ºC.

7-6. Hi POWER Operation

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

When [Hi POWER] button is pressed while the indoor unit is in Auto or Cooling operation, 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 setting temperature drops 3°C.

(The value of the setting temperature on the

remote control does not change.)

• If the room temperature is higher than the setting temperature by 3.5°C or more, the horizontal louver moves to the Hi POWER position automatically. Then when the room temperature is 1°C less than the setting temperature the horizontal louver returns

automatically.

• FAN speed : [AUTO]

If the room temperature is higher than the setting temperature by 3.5°C or more, the air conditioner operates at maximum airflow level. If the room temperature is higher than the setting temperature by less than 3.5°C, the air

conditioner operates at normal airflow level.

• FAN speed : One of 5 levels

If the room temperature is higher than the setting temperature by 3.5°C or more, the air conditioner operates at higher consecutive airflow level. If the room temperature is higher than the setting temperature by less than 3.5°C, the air conditioner operates at normal airflow

level.

· The indoor unit's fan speed level increase 1 tap

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

(4) The Hi POWER mode can memorize with timer function.

7-7. QUIET Operation

When the [QUIET] button is pressed, the fan of the indoor unit will be restricted the revolving speed at speed L− until the [QUIET] button is pressed once again (cancel Quiet mode).

Quiet mode is the system which, control the revolving speed of indoor fan to work constantly at lower than speed L. In addition, noise level of indoor unit is less

than usual.

Remarks :

1. Quiet mode is unable to work in dry mode.

2. Quiet mode is appropriate to work with less cooling load condition. Because of the fan speed L− may cause not enough the cooling capacity.

7-8. ECO Operation

Cooling operation
