2.3.9 Frequency control when there is CT over current protection
2.3.10 High pressure protection (Multi)
When the input signal of pressure switch is high level:1, that shows there is no protection.
When the input signal of pressure switch is low level: 0 for 1 minute, that shows high pressure
protection works. At this time, compressor stops, outdoor will send the alarm signal. The alarm can be
resumable. If in 60 minutes, the failure occurs 3 times, the failure can be confirmed and send failure
code to indoor. Meanwhile, by controling the max. condensate temp. Tc (cooling) or TmAVE (heating),
please confirm as follow:
In nominal cooling/dry/heating mode, high pressure can be controlled by limiting the max. frequency.
2.3.11 Low pressure protection (Multi)
(1) When compressor is running, if output signal of low pressure switch is low level: 0 for 1
minute continously, compressor will stop,outdoor alarms. The alarm can be resumable. If in 60
minutes, the failure occurs 3 times, 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 continously, alarm will occur.
