Haier Function control 11 C ice_temp_3 5 ice_temp_3 3 9 C Increasing slowly _____ 8 C icetemp_3 2 Keeping the frequency 7 c ice_temp_3 7Ю ice_temp_2 5 C ice_temp_1 ЗГ Decreasing rapidly ice_temp_1 0 C Stop Decreasing slowly When Tpgindoor ice_temp_1 C the frequency of the compressor decreases at the speed of 1HZ 1 second When Tpg indoor ice_temp_2 C the frequency of the compressor decreases at the speed of 1 HZ 1 Oseconds When Tpg indoor begins to rise again and ice_temp_2 Tpg_indoor ice_temp_3 C the frequency of the compressor doesn t change When ice_temp_3 Tpg indoor ice_temp_3 3 C the frequency of the compressor increases at the speed of 1 HZ 1 Oseconds For example Tpg_indoor 0 C last 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 C the compressor recovers 5 2 5 6 The frequency limitation of modification rate In the field which is controlled by high frequency if the modification rate is not high enough the control driven chip will enter into weak magnetic control this will help to relieve the problem of modification rate If during the course of weak magnetic control the modification rate is still not high enough enter into the control of decreasing frequency until the alarm of modification rate is relieved 5 2 5 7 Temperature protection of the outdoor refrigerating coil When the defrosting temperature and the sensor s temperature are higher than 65 C the frequency of the compressor decreases 1hz 1 Oseconds Keep the frequency until it decreases to the lowest frequency When the temperatures are lower than 65 C and higher than 60 C keep the frequency of the compressor When the temperatures are lower than 60 C relieve the defrosting temperature protection Haier Domestic Air Conditioner 26
