This is a fixed capacity type air conditioner, which uses AC motor for an indoor fan. The AC motor drive circuit is mounted in the indoor unit. And electrical

parts which driving the compressor and the outdoor

fan motor, are mounted in the outdoor unit.

The air conditioner is controlled by the controller mounted in the indoor unit. The controller operates all components based on the commands transmitted from the remote control and the feedback data of the sensor is as follow:

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

•The temperature measurement at the indoor heat exchanger by the indoor heat exchanger temperature sensor

• Indoor fan motor operation control

• Louver motor control

• LED display control

• Outdoor fan motor operation control

• 4-WAYS-VALVE operation control

(Heat pump model only)

• Compressor operation control

• Receiving the information of the operation

status and judging the information or the indication of errors

8-6. How to Set Remote Control Selector

Switch

When two indoor units ae installed in seperated rooms, there is no need to change the selector switch.

When two indoor units are installed in the same room or the adjacent two rooms, they may be controlled simultaneously with a single remote control. To prevent this, set either unit and its remote control to B setting. (Both units are set to A setting before shipment.) The remote control signal is not recived when the

indoor unit setting is different from the remote control one.

1. Set the remote control selector switch with the indoor unit.

1) Turn the circuit breaker of the main power switch off before setting the selector switch.

2) Remove the Air inlet grille and Front panel. (Refer to page 64, 10-1)

3) Select the terminal of selector switch from [A position] to [B position].

9-1. Troubleshooting Procedure

9-2-2. Incorrect cable connection between Indoor

and outdoor units

Follow the details of 9-2. Basic Chec k Items . If there is no trouble corresponding to 9-2, check whether or not there are faulty parts following 9-4. Self-Diagnosis by Remote Control.

9-2. Basic Check Items

9-2-1. Power supply voltage

The line voltage must be AC 220 − 240V. If it is not within this range, the air conditioner may not operate normally.

The indoor unit is connected to the outdoor unit with 5 cables (Heat pump model) or 3 cables (Cooling Only model). Check that the indoor and outdoor units have been properly connected with terminals assigned the same numbers. If the connectors are not properly connected, the outdoor unit will not operate normally, or OPERATION lamp and TIMER lamp will blink (5Hz).

9-2-3. Program control

The microcontroller operates as shown in Table 9-2-1 to control the air conditioner. If there are any operational problems, check whether or not the problems correspond to Table 9-2-1. If they correspond to the Table, they are not problems with the air conditioner, but they are indispensable operations to control and maintain the air conditioner properly.

Table 9-2-1

No. Operation of air conditioner Descriptions

1 When the main power supply is turned on,

the OPERATION lamp on the indoor unit blinks.

2 The indoor fan motor speed does not change

in the Dry operation.

The OPERATION lamp blinks to indicate that power is turned on.

If the [ ] button is pressed, the lamp stops blinking.

The indoor fan motor speed is automatically controlled in the Dry operation.

3 The compressor is not turned off even though

the room temperature is in the range that the compressor is turned off.

4 The compressor is not turned on and off even

though the thermo control is operated in the Dry operation.

5 The PRE-DEF. lamp is indicated when the

Heating operation starts.

6 The outdoor fan motor stops in the Heating

operation.

7 The compressor is not turned on even though

the room temperature is in the range that the compressor is turned on.

8 The operation mode changes in the

Automatic operation.

9 The Fan only operation continues in the

Automatic operation.

10 The Hi-POWER operation does not work.

The compressor has a function that it is not turned off for 3 minutes after it is turned on even though the room temperature is in the range that the compressor is turned off.

In the Dry operation, the compressor is turned on and off automatically at the regular intervals, independent of the thermo control.

The PRE-DEF. lamp is indicated during the Defrosting operation or if the indoor heat exchanger temperature is low when the Heating operation starts. At this time, the indoor fan motor stops to prevent cold air from blowing in the room.

When the indoor heat exchanger temperature is high, the outdoor fan motor is stopped by the high-temperature limit control operation.

The compressor is not turned on in the restart delay timer (3-minutes timer) operation. It is also not turned on after the power supply is turned on because of this timer operation.

In Automatic operation, the room temperature is detected all time for control fan speed and the operation mode is changed every 15 minutes according to difference between the room temperature and the preset temperature.

When the room temperature is in the range (Preset temperature ± 1°C), the Fan only operation is selected.

This operation does not work when the unit is in the Dry operation or Fan only operation.
