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

Operations according to the commands from the indoor unit

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

• Defrost control in heating operation (Temperature measurement by the Indoor heat exchanger, control the four-way valve and outdoor fan motor control)

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 7-2-3)

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 and

8-5-3. Evacuating

After the piping has been connected to the indoor unit, you can perform the air purge together at once.

AIR PURGE

Evacuate the air in the connecting pipes and in the indoor unit using a vacuum pump. Do not use the refrigerant in the outdoor unit. For details, see the manual of the vacuum pump.

Be sure to use a vacuum pump with counter-flow prevention function so that inside oil of the pump does not flow backward into pipes of the air conditioner when the pump stops.

1. Connect the charge hose from the manifold valve to the service port of the gas side packed valve.

2. Connect the charge hose to the port of the vacuum pump.

3. Open fully the low pressure side handle of the gauge manifold valve.

4. Operate the vacuum pump to start evacuating. Perform evacuating for about 15 minutes if the piping length is 20 meters. (15 minutes for 20 meters) (assuming a pump capacity of 27 liters per minute.) Then confirm that the compound pressure gauge reading is -101 kPa ( 76 cmHg).

5. Close the low pressure side valve handle of gauge manifold.

6. Open fully the valve stem of the packed valves (both sides of Gas and Liquid).

7. Remove the charging hose from the service port.

8. Securely tighten the caps on the packed valves.

Open the valve stem all the way out; but do not try to open it beyond the stopper.

Securely tighten the valve stem cap with torque in the following table:

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.

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

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.

10. HOW TO REPLACE THE MAIN PARTS

WARNING

• Since high voltages pass through the electrical parts, turn off the power without fail before proceeding with the repairs.

Electric shocks may occur if the power plug is not disconnected.

• After the repairs ha ve been completed (after the front panel and cabinet have been installed), perform a test run, and check for smoking, unusual sounds and other abnormalities.

If this check is omitted, a fire and/or electric shocks may occur. Before proceeding with the test run, install the front panel and cabinet.

• Ensure that the following steps are taken when doing repairs on the refrigerating cycle.

1. Do not allow any naked flames in the surrounding area.

If a gas stove or other appliance is being used, extinguish the flames before proceeding. If the flames are not extinguished, they may ignite any oil mixed with the refrigerant gas.

2. Do not use welding equipment in an airtight room.

Carbon monoxide poisoning ma y result if the room is not properly ventilated.

3. Do not bring welding equipment near flammable objects.

Flames from the equipment may cause the flammable objects to catch fire .

• If keeping the power on is absolutely unavoidable while doing a job such as inspecting the cir-

cuitry, wear rubber gloves to avoid contact with the live parts.

Electric shocks may be received if the live parts are touched. High-voltage circuits are contained inside this unit.

Proceed very carefully when conducting checks since directly touching the parts on the control circuit board may result in electric shocks.
