Error occurs when the EEPROM DATA in the outdoor unit main PBA and inverter PBA is different from each other. Check the
model name and EEPROM code to use it

Error occurs when DC LINK value is not normal (DC LINK VOLTAGE: 280~320V)
Check the value of DC link when error occurs and check the reactor disconnection

Error occurs when heat sink of the inverter PBA exceeds rated range
Clean and remove any dust and other foreign substances on the outdoor unit and then check the connection between heat sink
and inverter PBA
Make sure grease is applied properly and screw is firmly fixed

Detect the input sensor while the set is in stop status to check if there’s any problem
When error occurs, turn on/off the power for number of time and if same error occurs while the power is off, change the inverter

Error occurs when there is no EEPROM data in the set. Check the model name and insert EEPROM for corresponding model or
load the EEPROM data.
