3714.4. Error Codes TableNote:“O” - Frequency measured and fan speed fixed.The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until “beep” sound heardfollowing by pressing the “RESET” button at remote controller.Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to ErrorCodes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound ischanged from one “beep” to four “beep” sounds.Diagnosisdisplay Abnormality / Protection control AbnormalityJudgementEmergencyoperation Primary location to verifyH00 No abnormality detected — Normal operation —H11 Indoor / outdoor abnormal communication > 1 min after startingoperationIndoor fan operationonly• Internal / external cable connections• Indoor / Outdoor PCBH12 Connection capability rank abnormal — — —H14 Indoor intake air temperature sensorabnormality Continue for 5 sec. — • Intake air temperature sensor(detective or disconnected)H15 Outdoor compressor temperature sensorabnormality Continue for 5 sec. — • Compressor temperature sensor(detective or disconnected)H16 Outdoor Current Transformer open circuit — — • Outdoor PCB• IPM (Power transistor) moduleH19 Indoor fan motor merchanism locked — — • Indoor PCB• Fan motorH23 Indoor heat exchanger temperaturesensor abnormality Continue for 5 sec.
