Displays No. of error detection, which occurred
most frequently, out of error detections occurred
after turning power on and starting operation.
This is retained in EEPROM memory till the cause of
compressor stop by first error occurs after turning
power on.

Displays No. of error detection, which occurred at
second place frequently, out of error detections
occurred after turning power on and starting
operation.
This is retained in EEPROM memory till the cause of
compressor stop by first error occurs after turning
power on.

Displays No. of error detection, which occurred
at third place frequently, out of error detections
occurred after turning power on and starting
operation.
This is retained in EEPROM memory till the cause of
compressor stop by first error occurs after turning
power on.
