Value Of Thermistor - Haier HSU-18LEK03/R2 Service Manual

5.2.5.5 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.
5.2.5.6 Temperature protection of the outdoor refrigerating coil
When the defrosting temperature and the sensor's temperature are higher than 65 , the frequency of
the compressor decreases 1hz/10seconds. Keep the frequency until it decreases to the lowest
frequency. When the temperatures are lower than 65
the compressor. When the temperatures are lower than 60 , relieve the defrosting temperature
protection.
