![]() Reason for operation:compressor drive output error, compressor error (lock, missing etc.), break down ![]() Reason for operation:outdoor heat exchanger temp. Reason for operation:outdoor fan drive system error Reason for operation:Disconnection or short-circuit of discharge tem. Reason for operation:Out of place, disconnected or short-circuited outdoor tem. Reason for operation:current-address circuit error Reason for operation:Position-detect circuit error or short-circuit between windings of the compressor Reason for Operation:The inverter operates an over-current protective circuit. Reason for Operation:The operation command signal is not sent to the outer side. (1) Defective wiring of connecting cable (2) Operation of compressor thermo. Reason for Operation:The serial signal returned from the started operation is not sent to the indoor side. Reason for operation:trouble with indoor fan lock or indoor fan circuit Reason for operation:out of place, disconnection, short-circuit, or migration of heat exchanger sensor (TC sensor) Reason for Operation:Disconnection of short-circuit or room temperature sensor (TA sensor). However, the check codes are not removed even if the power supply is turned off because they are stored in fixed memory. After servicing by check code, turn off the power supply breaker, and turn on the power supply breaker again so that the memory in the microcomputer returns the initial state. After servicing, push the button to return to normal mode.Ģ. The check code can be confirmed on the remote controller for servicing.ġ. When items B and C, and a part of item B and item E are concurrent, the block of item B is preferred.ģ. The contents of items B and C and a part of item E are displayed when the air conditioner is operatedĢ.
