Brief introduction to electrical function
During cooling-dehumidification running, low-load protection is carried out according to indoor coil-pipe
temperature; whereas, the displayed frequency is “58Hz”.
The minimum frequency is displayed when indoor coil- pipe temperature is lower than 2
and coil-pipe
temperature is above -0.5
.
When thermal conversion temperature is lower than 0.5
, selecting 3 minutes stand-by status.
When indoor coil-pipe temperature is 2.1
, the compressor restarts.
During trial running, the low-load protection control can be overlooked.
1.1.7.2 High-load protection
During heating running, if the indoor coil-pipe temperature is too high, the compressor must be stopped for
protection to prevent it from damaging due to the system overheating. See the following figure for details:
Thermal conversion temperature

62 (undetermined)

Parameters
Frequency A 80Hz
Frequency B 72Hz
Frequency C 50Hz
Frequency D 30Hz
When high-load protection is limited to act twice within 30 minutes, it is high-load protection alarm.
When indoor coil pipe temperature is lower than 45
, it comes back to normal control.
The frequency of high load protection is priority.
