Troubleshooting

Possible reasons

Malfunction of drain system

Pump motor disconnected

or at wrong position, or

the ﬂoat switch broken

down, or the ﬂoat switch

disconnected or at wrong

position.

Faulty ambient

temperature sensor

Sensor disconnected,

or broken, or at wrong

position, or short circuit.

Faulty coil temperature

sensor

Sensor disconnected,

or broken, or at wrong

position, or short circuit.

Abnormal communication

between indoor wired

controller and indoor unit

PCB

Wrong connection, or

the wired controller be

disconnected, faulty PCB.

EEPROM error

Loss of data EEPROM.

Indoor coil temperature too

high in cooling mode

Refrigerant leakage or

indoor coil sensor falling

off or failure on 3 phases

outdoor unit.

: Optional equipment

Outdoor toubleshooting

LED ﬂash times of outdoor control board

Troubleshooting

Possible reasons

Protection of discharging temp.

too high or sensor abnormal

After compressor starts up, if TD

is over 120°C, 10seconds later

compressor stop.

Phase sequence abnormal

Power supply phase sequence

wrong.

Pressure abnormal

High/Low pressure switch acts

abnormal.

After compressor running for 3

minutes, if switch is detected

unconnected for 30 seconds, it

alarms, if it occurs 3 times in 30

minutes, confirm this failure.
