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.
7.1.5.7 Temperature protection of the outdoor refrigerating coil
When the defrosting temperature and the sensor’s temperature are higher than 68℃, the frequency of
the compressor decreases 1hz/10seconds. Keep the frequency until it decreases to the lowest
frequency. When the temperatures are lower than 68℃ and higher than 62℃, keep the frequency of
the compressor. When the temperatures are lower than 62℃, relieve the defrosting temperature
protection.
