If the output current of inverter exceeds the specifications, it makes the compressor stopping.
(iii) Anomalous stop control
1) If the inverter output current value excceds the setting value within 80 seconds the compressor stops.
2) After 3 minutes delay. the compressor restarts, but if this anomaly occurs 2 times within 20 minutes after
this initial detection.
Note (1) Except that the fan speed is Hi in heating operation and silent mode control.
