Error contents
Open/Short of temp sensor (TH) built in outdoor IGBT is
detected.
Detection circuit of inverter current (Idc) detects
over-current.
Compressor lock is detected.
Abnormal current is detected during stop of compressor.
High pressure SW operates.
IPDU for outdoor fan detects each error.
Short-circuit protection operation (Momentary over-current)
of compressor motor drive circuit element works.
Position detection error of compressor motor is detected.
NOTE)
Even the same error contents such as communication error, the check codes display may differ according to the detected device.
In case of check code detected by a central controller of the remote controller, it does not exactly have direct influence to operation of the air conditioner.
