Remarks: when the outdoor temperature is high, there’s compensation for AC current protection.
ŁWhen the outdoor environment temperature is higher than , AC current protection value
decreases by 10AD
łWhen the outdoor environment temperature is higher than ,AC current protection value
decreases by 15AD
ŃWhen the outdoor environment temperature is higher than ,AC current protection value
decreases by 20AD

Functions and Control
5.2.5.4 The protection function of AC current:
During the starting process of the compressor, if the AC current is greater than 15A, the frequency of
the compressor decreases at the speed of 1HZ/second.
During the starting process of the compressor, if the AC current is greater than 13A, the frequency of
the compressor decreases at the speed of 0.1HZ/second.
During the starting process of the compressor, if the AC current is greater than 11A, the frequency of
the compressor increases at the prohibited speed.
During the starting process of the compressor, if the AC current is greater than 10A, the frequency of
the compressor increases at the speed of no faster than 0.1HZ/second.
