TROUBLE SHOOTING
7-1. SELF-DIAGNOSTIC FUNCTION
7-1-1. Wired remote controller (1)
! When trouble occurs during operation, the unit stops and enters the self-diagnostic mode, and displays the trouble loca-
tion with the timer lamps on the remote controller. All the other lamps are OFF.
@ To activate the self-diagnostic function for service, press the UP and DOWN buttons simultaneously for more than two
TEMP.
seconds during operation with lamp ON.
# The timer lamps show the latest trouble. Trouble data is memorized until the next trouble occurs, even when the breaker
turns OFF. To clear the memory, press the UP and DOWN buttons simultaneously for more than two seconds during the
test run.
$ All buttons except the POWER ON/OFF button are unavailable during the self-diagnostic mode.
% To release the self-diagnostic mode, press the POWER ON/OFF button.

7-1-2. WIRED REMOTE CONTROLLER(2)
1) When malfunction occurs during operation
When a malfunction occurs, the indoor and outdoor units stop and the malfunction is displayed on the LCD of the remote
controller.
(1) ON the set temperature display part, “CHECK” appears, and the unit
address and the check code are displayed alternately at one-second
intervals. (Check mode)
Example
CHECK mode
Check
code
Unit
address
(2) When one remote controller controls several units in the group con-
trol, the LCD shows the unit address and check code of the first malfunctioning unit.
(3) To cancel the check mode, press the ON/OFF button. In remote
ON/OFF control, press the remote ON/OFF switch. In centralized
control, turn OFF the ON/OFF button of centralized controller.
Check button
NOTE: The latest check code is memorized, even if the check mode is cancelled by the way mentioned above. It takes
60 seconds maximum to display the memorized check code.
2) How to use the self diagnostic function for service
A. For normal control with one unit and one remote controller
(1) Pressing the CHECK button on the remote controller twice starts the self diagnostic function.
(2) During the self diagnostic function, “CHECK MODE” appears at two positions on the remote controller display. Then, at
least 10 seconds later, the unit address and the check code is alternately displayed at one-second intervals.
(3) Check and repair the unit according to the check code.
B. For group control using one remote controller
(1) Pressing the CHECK button on the remote controller twice starts the self diagnostic function.
(2) Press the TEMP. button or TEMP. button on the remote controller to advance or go back to the unit address.
Each time TEMP. button is pressed, the unit address advances by one. Each time TEMP. button is pressed,
▲
▲ ▼
▼
the unit address goes back by one.
The check code and the unit address, appear alternately.
(3) The check code “U8” means no malfunction has occurred since installation.
The check code “EO” means the following conditions:
● The unit address displayed on the remote controller does not apply to any unit.
● power is not supplied to the unit.
● Signal transmitting/receiving circuit is abnormal.
(4) Check and repair the unit according to the check code.

Diagnosis of malfunction Cause Check points
Abnormality of room temperature thermistor (RT1)
Abnormality of indoor coil
thermistor (RT2)
1) Bad contact of thermistor
2) Damaged thermistor
1) Check the thermistor.
2) Measure the resistance of the thermistor.
Normal resistance should be as follows.
0°C···15kΩ 30°C····4.3kΩ
10°C·····9.6kΩ 40°C·····3.0kΩ
20°C·····6.3kΩ
If the resistance is normal, replace the indoor
controller board.
(P4) Abnormality of drain sensor 1) Bad contact of transmission
(P5) Malfunction of drain pump 1) Malfunction of drain pump
(P6) Coil frost protection is work-
ing.
(P8) Abnormality in outdoor unit 1) Wrong wiring of indoor/outdoor
wire
2) Damaged thermistor
2) Damaged drain sensor
1) Short cycle of air cycle
2) Dirty air filter
3) Damaged fan
4) Abnormal refrigerant
connecting wire
2) Reversed phase
3) Protection device is working
4) Damaged outdoor coil thermistor
1) Check the connector.
2) Measure the resistance of the thermistor 4 ~
5.
As for the normal resistance, refer to the case
of P1.
If the resistance is normal, replace the indoor controller board.
1) Check the drain pump.
2) ● Check the drain sensor.
● Check the drain sensor heater. Normal resistance should be 82Ω.
If the resistance is normal, replace the indoor controller board.
1) Clear obstructions from the air cycle.
2) Clean the air filter
3) Check the fan.
4) Check the refrigerant temperature.
1) Check the indoor/outdoor connecting wire.
2) Change the connection of electric wiring.
3) Check the protection device.
4) Measure the resistance of the outdoor coil thermistor. If the resistance is normal, replace the
outdoor controller board.
