The parameters or settings (Dip switches) on the remote control unit are incorrectly configured, leading to operational errors.

This error indicates a problem with the electrical power supply. It could be a phase failure (loss of one phase) or a phase imbalance (uneven voltage across phases).

The voltage across the different power phases is not balanced. This can stress the unit's components and lead to errors.

A general power supply issue is detected. This could involve voltage irregularities or instability in the electrical feed to the unit.

The system has detected low suction pressure, which typically indicates a lack of refrigerant (freon) in the system.

The system has detected excessively high pressure. This can be caused by several factors hindering the refrigerant flow.

The 4-way valve, which directs refrigerant flow for heating or cooling, is not operating correctly. This can be due to mechanical issues or valve coil problems.

This error occurs on specific models in cold conditions and indicates that the indoor unit's heat exchanger may be freezing.

The system has detected a leak in the refrigerant (freon) circuit. This requires immediate attention to prevent system damage and environmental harm.

This error points to an issue within the refrigerant circuit, such as a freon leak or a closed service valve, which obstructs refrigerant flow.

The inverter board is triggering a protection due to low DC voltage. This suggests an issue with the power conversion or supply to the inverter.

This error indicates a failure within the inverter system, specifically the IPM (Intelligent Power Module) transistor module or the main control board.

The compressor is drawing too much current, indicating it might be jammed or there's a phase failure in the power supply. A weak power network can also cause this.

The compressor is overheating. This can be due to a lack of freon, a dirty condenser heat exchanger, or restricted airflow.

The inverter is triggering a Power Factor Correction (PFC) protection. This usually relates to the power supply quality or the inverter's ability to maintain a stable power factor.

This error indicates a problem with the DC inverter system, specifically a malfunction of the IPM transistor module or the compressor jamming.

The compressor speed is not matching the signals being sent from the control board. This could be due to a faulty IPM transistor module or a jammed compressor.

This error indicates a problem with the DC fan motor in the outdoor unit. It may be disconnected, malfunctioning, or have wiring issues.

The temperature sensor at the outlet of the indoor unit is faulty. It might be shorted or broken, affecting temperature readings.

The temperature sensor on the compressor suction line is faulty. It may be shorted, broken, or disconnected. A closed service valve can also cause this.

The temperature sensor measuring the temperature at the condenser outlet is faulty. It could be shorted, broken, or disconnected.

The temperature sensor monitoring the pipe temperature is faulty. It may be shorted, broken, or disconnected, requiring inspection of the sensor and its wiring.

The temperature sensor measuring the compressor discharge temperature is faulty. It could be shorted, broken, or disconnected.

The high pressure sensor has activated, indicating excessive pressure in the system. This could be due to an open circuit in the sensor itself.

The low pressure sensor has activated due to an open circuit. This suggests a problem with the sensor or its connection, potentially indicating low pressure.

There is an open circuit in the current sensor, or the unit is consuming abnormally low current. This could indicate a faulty sensor or an issue with the power module.

This error indicates the inverter protection has been triggered due to overheating of the IPM transistor board or a malfunction of the outdoor unit's main board.

The system is operating normally and no errors have been detected. This is a status code indicating normal function.

There is a failure in communication between the indoor and outdoor units. The control board may be defective, or there's a wiring issue.

The combined capacity of the indoor units does not match the capacity of the outdoor unit. This is an installation or configuration error.

The air sensor, likely measuring ambient or room temperature, is experiencing a short circuit or is disconnected. This affects temperature regulation.

The temperature sensor monitoring the compressor has an issue. It's either short-circuited or has an open circuit, meaning it's not sending proper temperature data.

The external unit is consuming unusually low current. This can indicate insufficient freon, a faulty current transformer circuit, or a failed IPM power module.

The temperature sensor on the refrigerant suction pipe is faulty, either short-circuited or open. This prevents accurate temperature monitoring of the refrigerant.

The fan motor in the indoor unit is jammed or malfunctioning. This could be due to the motor itself, the board, or loose wire connectors.

The condensate drainage system is blocked, or the float sensor is not working correctly. This prevents water from draining, potentially causing overflow.

The first evaporator temperature sensor (N1) is either short-circuited (closed) or disconnected. This affects the accurate measurement of the evaporator's temperature.

The second evaporator temperature sensor (N2) is faulty, either short-circuited (closed) or broken. This impairs the accurate reading of the evaporator temperature.

This error indicates a problem with the ionization unit or the internal control board of the unit. Either component may be faulty.
