16.4.22 F90 (Power Factor Correction Protection)
Malfunction Decision Conditions
To maintain DC voltage level supply to power transistor.
To detect high DC voltage level after rectification.
Malfunction Caused
During startup and operation of cooling and heating, when Power Factor Correction (PFC) protection circuitry at
the outdoor unit main PCB senses abnormal DC voltage level for power transistors.
When DC voltage detected is LOW, transistor switching will turn ON by controller to push-up the DC level.
When DC voltage detected is HIGH (391Vdc – 425Vdc), active LOW signal will send by the controller to turn OFF
relay RY-C.
Troubleshooting
Note:
Some error code might not applicable for this model.
