Description of error
Temperature sensor built into indoor IGBT (TH)
has been open / short-circuited.
Inverter current (Idc) detection circuit detects
overcurrent.
Compressor lockup is detected
Abnormal current is detected while inverter
compressor is turned off.
High-pressure SW is activated.
Temperature sensor built into IGBT (TH) detects
overheating.
High-pressure (Pd) sensor detected a value over
the criteria.
Outdoor fan IPDU detects error.
Short-circuit protection for compressor motor
driver circuit components is activated (momentary
overcurrent).
Compressor motor position detection error is
detected.
