Functions and control

Domestic air conditioner
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.
7.1.5.7 Temperature protection of the outdoor refrigerating coil
When the frequency are higher than 40Hz,and the defrosting sensor’s temperature are higher than
68
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 68
ć
and higher than 62
ć
,
keep the frequency of the compressor. When the temperatures are lower than 62
ć
, relieve the
defrosting temperature protection.
