unit will stop to alarm and the failure can be resumed after being
electrified again.

3.2.8. Frequency control when there is CT over current protecon
3.2.9. High pressure protecon (Mul)
When the input signal of pressure switch is high level:1, that shows there is no protecon.
When the input signal of pressure switch is low level: 0 for 1 minute, that shows high pressure
protecon works. At this me, compressor stops, outdoor will send the alarm signal. The alarm can be
resumable. If in 60 minutes, the failure occurs 3 mes, the failure can be confirmed and send failure
code to indoor. Meanwhile, by controling the max. condensate temp. Tc (cooling) or TmAVE (heang),
please confirm as follow:
In nominal cooling/dry/heang mode, high pressure can be controlled by liming the max. frequency.
3.2.10. Low pressure protecon (Mul)
(1) When compressor is running, if output signal of low pressure switch is low level: 0 for 1
minute connously, compressor will stop,outdoor alarms. The alarm can be resumable. If in 60
minutes, the failure occurs 3 mes, the failure can be confirmed and send failure code to indoor.
(2) When compressor no running, if output signal of low pressure switch is low level: 0 for 30
seconds connously, alarm will occur.
