Two beeps indicate that the Test Run operation has started in Forced heating mode. This is typically used for servicing purposes.

Three beeps signal that the unit is in standby for the Remote Control Number Switch Mode. This mode allows selection of different transmission codes to avoid interference.

Four beeps indicate that the unit is in standby for the Remote Control Receiving Sound Off/On Mode. This allows you to turn the sound feedback for remote signals on or off.

A beep sound is heard as confirmation when a transmission code has been changed and stored, or when a setting like sensitivity or timer is confirmed.

The e-ion LED is blinking, indicating a problem with the e-ion air purification system.

The 4-way valve has switched abnormally four times within 30 minutes. This indicates a potential problem with the valve itself or its electrical connections.

The indoor unit's heat exchanger may be freezing. The outdoor unit will display 'F17' to the corresponding indoor unit and 'H39' to others. This is indicated when the indoor intake air temperature is significantly different from the indoor pipe temperature, or when the indoor pipe temperature is too low.

The power factor correction circuit has entered protection mode four times within 10 minutes, indicating an abnormality with this circuit, potentially a faulty outdoor PCB.

The system has detected a potential gas leak or low pressure issue. The Timer LED will blink, and the unit will stop operation. This occurs if specific low-pressure conditions are met twice within 20 minutes.

The compressor has experienced abnormal revolutions four times within 20 minutes. This suggests a faulty power transistor module or a compressor lock.

The compressor discharge pressure has overshot its limit four times within 30 minutes, triggering protection. This requires checking the refrigeration system.

The outdoor unit has entered high pressure protection during cooling operation twice within 20 minutes. This requires checking the refrigeration system and outdoor air circuit.

The Intelligent Power Module (IPM) has overheated, causing the compressor to stop. The Timer LED will blink to signal this error. This happens if the IPM temperature reaches 100°C four times within 20 minutes.

The compressor has overheated, causing it to stop. The Timer LED will blink to indicate this error. This happens if the compressor discharge temperature exceeds 110°C four times within a 20-minute period.

The unit has triggered total running current protection three times within 20 minutes. This requires checking the refrigeration system, power source, or a potential compressor lock.

The system has detected excessive DC peak current to the IPM, causing operation to stop. The Timer LED will blink. This fault occurs repeatedly if the set current value is exceeded frequently.

The indoor unit or standby units have operated abnormally three times within 40 minutes. This indicates a potential issue with wiring, piping, the expansion valve, or the indoor heat exchanger sensor.

This code signifies an issue with the wiring or piping connection. It could be due to incorrect connections or problems with the expansion valve.

The indoor gas sensor has been abnormal for 6 hours. The Timer LED and Patrol LED will blink, and the air conditioner will operate in normal mode with the Patrol sensor power turned off.

The outdoor high pressure sensor has shown an abnormality, specifically an open circuit, for one minute while the compressor is stopped. This indicates a problem with the sensor or its connections.

The outdoor fan motor has locked or shown abnormal feedback twice within 30 minutes. This suggests the fan motor is obstructed or malfunctioning.

The unit has entered indoor high pressure protection mode during heating. This can be caused by issues with the indoor heat exchanger, a dirty air filter, or a short circuit in air circulation.

The unit has entered indoor freeze protection mode during cooling. This can be caused by issues with the indoor heat exchanger, a dirty air filter, or a short circuit in air circulation.

A long beep indicates that the sound confirmation for receiving remote control signals has been turned on. You will now hear beeps when the remote control is used.

The PATROL LED is blinking, indicating an error with the gas sensor. This sensor is used to monitor air quality.

The POWER LED blinking is normal during specific operations such as Hot Start, defrost cycle, operation mode judgment, or when the ON timer is sampling.

The Power LED blinks with a 0.5-second interval (on and off). This typically signifies that the unit is in a special operating mode, such as residual heat removal, hot start, deice operation, mode judgment, or ON timer sampling.

The Power LED blinks with a longer interval (2.5 seconds on, 0.5 seconds off), indicating that the unit is in standby mode and waiting for further commands.

A short beep indicates that the sound confirmation for receiving remote control signals has been turned off. You will no longer hear beeps when the remote control is used.

The Timer LED is blinking, indicating that an abnormality has occurred during operation. The unit may have stopped its operation.
