frequency of the compressor increases at the speed of no faster than 0.1HZ/second.

5.2.6.4 The protection function of AC current:
During the starting process of the compressor, if the AC current is greater than 10.5A, 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 9.5A, 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 9.0A, the frequency of
the compressor increases at the prohibited speed.
During the starting process of the compressor, if the AC current is greater than 8A, the frequency of
the compressor increases at the speed of no faster than 0.1HZ/second.
Remarks: when the outdoor temperature is high, there’s compensation for AC current protection.
ŁWhen the outdoor environment temperature is higher than 40ć, AC current protection value
decreases by 1.5A
łWhen the outdoor environment temperature is higher than 50ć,AC current protection value
decreases by 2.5A
5.2.6.5 Antifreezing protection of the indoor heat exchanger
When refrigerating/heating, prevent freezing.
Tpg_indoor Ўis the minimum value of the effective indoor unit (start it and it is in accord with the
running state).

When Tpg_indoorLJ ice_temp_1 , the frequency of the compressor decreases at the spećed of
1HZ/1second.
When Tpg_indoorLJ ice_temp_2 , the frequency of the compressor decreases at the speed of ć
1HZ/10seconds.
When Tpg_indoor begins to rise again, and ice_temp_2LJ=Tpg_indoorLJ= ice_temp_3 , the frequency ć
of thecompressor doesn’t change.
When ice_temp_3LJTpg_indoorLJice_temp_3+3 , the frequency of the compressor increases at the ć
speed of 1HZ/10seconds.
For example, Tpg_indoor<= 0ćˈlast for 2 minutes, and then the outdoor unit will stop, and report
underload malfunction, but don’t send malfunction report to the indoor.
The compressor stops for more than 3 minutes, Tpg_indoor> ice_temp_3+2 , the compressor ć
recovers.
