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 The socket protect
If the socket temperature is higher than 120
ć
,the outdoor unit will stop,and report
malfunction(the LED light flashing 36 times).The compressor stops for more than 3 minutes,the
compressor recovers.

When the defrosting temperature and the sensor’s temperature are higher than 65
ć
, 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
ć
and higher than 60
ć
, keep
the frequency of the compressor. When the temperatures are lower than 60
ć
, relieve the
