CAUSE
COUNTERMEASURE
06
1. Error occurrence condition
After outdoor unit operation
is started, EEPROM cannot
be accessed because of
disturbance or device error.
2. Relevant operation
Error is displayed on LED of
outdoor unit. *Outdoor unit
operation is not controlled.
3. Clearance
EEPROM can be accessed
correctly.
1. Remove noise sources near outdoor
unit.
2. Replace outdoor unit control printed
circuit board.
EEPROM cannot be accessed
because of disturbance, device
error, etc.
Replace outdoor unit control printed
circuit board.
Model information is not
memorized, or erased for some
reason.

error
1. Check if the wiring of discharge
temperature sensor THD1 loosens or
comes off. And check the resistance
of sensor. If it's abnormal,
replace sensor.
2. Check compressor power relay 1. If
it's abnormal, replace power relay.
3. Check CN24 (compressor 1) 12V
voltage output on outdoor unit control
printed circuit board. If it's abnormal,
replace printed circuit board.
4. Check magnetic contactor 1. If it's
abnormal, replace contactor.
5. Check additional refrigerant amount
and recharge suitable refrigerant.
6. Temporary data transmission trouble
due to Effect of extraneous noise, etc.
Operation is not affected.
7. Compressor overload operation
Check "High-pressure error". Motor
protector is reset at 61 C +/-9 C.
8. Check compressor. If it's faulty,
replace compressor.
1. Discharge temperature
sensor THD1 is faulty.
3. Outdoor unit control printed
circuit board is faulty.
4. Magnetic contactor 1
is faulty.
5. Lack of refrigerant.
6. After 2 and half an hours
have elapsed since error is
displayed, error detection
is performed again and error
is not displayed.
7. Compressor motor protector
is operated.
8. Compressor is faulty.
1. Error occurrence condition
After outdoor unit operation
is started, error occurs in
model information, which is
memorized in EEPROM.
2. Relevant operation
1) All compressors are stopped.
2) Error is displayed on LED of
outdoor unit.
3. Clearance
Model information, which is
memorized in EEPROM is
recovered.
1. Error occurrence condition
After thirty minutes has
elapsed since compressor 1
starts to work, discharge
temperature 1 does not
reach to outdoor
temperature plus 10 C.
2. Relevant operation
1) After compressor error
occurs, compressor
recovery operation is
performed. However, if
defrosting control or oil
recovery operation is
performed, compressor
recovery is not operated.
2) Error is displayed on LED of
outdoor unit and output to
communication bus line.
3. Clearance
When 2 hours have elapsed
after error occurrence.
*Counting of 2-hour counter
starts if error occurs on any
compressors.
Error is cleared by turning
power off.
2. Compressor power relay 1
is faulty.
