1.Indication of capacity has been changed.(BTU base kW base)

2.Control method between indoor and outdoor has been changed.

3.Power supply method has been changed (change to supply from outdoor unit).

4.Power supply cord has been removed.

5.Indoor electronic control P.C. board has been changed.

6.Position of terminal block has been changed.

7.Indoor fan motor has been changed. ( AC DC)

8.Indoor heat exchanger has been changed.

9.The horizontal vane motor unit has been changed.

An external gear is added to the generalized stepping motor.

The unit is structured so that the driving torque and stopping torque would increase.

8 SERVICE FUNCTIONS

MSZ-GA22VA - E1

MSZ-GA25VA - E1

MSZ-GA35VA - E1

8-1. TIMER SHORT MODE

For service, set time can be shortened by short circuit of JPG and JPS the electronic control P.C. board. The time will be shortened as follows. (Refer to 9-7.)

Set time : 1-minute 1-second

Set time : 3-minute 3-second (It takes 3 minutes for the compressor to start operation. However, the starting time is shortened by short circuit of JPG and JPS.)

8-2. P.C. BOARD MODIFICATION FOR INDIVIDUAL OPERATION

A maximum of 4 indoor units with wireless remote controllers can be used in a room.

In this case, to operate each indoor unit individually by each remote controller, P.C. boards of remote controller must be modified according to the number of the indoor unit.

How to modify the remote controller P.C. board

Remove batteries before modification.

The board has a print as shown below :

Remote controller model : KM05B

NOTE : For remodelling, take out the batteries and press the OPERATE/STOP(ON/OFF) button twice or 3 times at first.

After finish remodelling, put back the batteries then press the RESET button.

J1 J2

The P.C. board has the print “J1” and “J2”. Solder “J1” and “J2” according to the number of indoor unit as shown in Table 1. After modification, press the RESET button.

How to set the remote controller exclusively for particular indoor unit.

After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the remote controller for the indoor unit.

The indoor unit will only accept the signal from the remote controller that has been assigned to the indoor unit once they are set.

The setting will be cancelled if the breaker has turned off, or the power supply has shut down. Please conduct the above setting once again after the power has restored.

8-3. AUTO RESTART FUNCTION

When the indoor unit is controlled with the remote controller, the operation mode, the set temperature, and the fan speed are memorized by the indoor electronic control P.C. board. The “AUTO RESTART FUNCTION” sets to work the moment power has restored after power failure. Then, the unit will restart automatically.

Operation

1 If the main power has been cut, the operation settings remain.

2 After the power is restored, the unit restarts automatically according to the memory. (However, it takes at least 3 minutes for the compressor to start running.)

How to release “AUT O RESTART FUNCTION”

1Turn off the main power for the unit.

2Solder the Jumper wire to JR07 on the indoor electronic control P.C. board. (Refer to 9-7.)

CN151 CN112

NOTE:

The operation settings are memorized when 10 seconds have passed after the indoor unit was operated with the remote controller.

If main power is turned OFF or a power failure occurs while AUTO START/STOP timer is active, the timer setting is cancelled.

If the unit has been off with the remote controller before power failure, the auto restart function does not work as the power button of the remote controller is off.

To prevent breaker off due to the rush of starting current, systematize other home appliance not to turn on at the same time.

When some air conditioners are connected to the same supply system, if they are operated before power failure, the starting current of all the compressors may flow simultaneously at restart.

Therefore, the special counter-measures are required to prevent the main voltage-drop or the rush of the starting current by adding to the system that allows the units to start one by one.

9 TROUBLESHOOTING

9-1. Cautions on troubleshooting

1.Before troubleshooting, check the following:

1)Check the power supply voltage.

2)Check the indoor/outdoor connecting wire for mis-wiring.

2.Take care the following during servicing.

1)Before servicing the air conditioner, be sure to turn off the unit first with the remote controller, and then after confirming the horizontal vane is closed, turn off the breaker and / or disconnect the power plug.

2)Be sure to turn OFF the power supply before removing the front panel, the cabinet, the top panel, and the electronic control P.C. board.

3)When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the components.

4)When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires.
