If keeping for 10s, the unit stops, 3 minutes later, the unit can
re-startup. If in 60 minutesthe unit occurs alarm for 3 times, the
failure can be eliminated.

Frequency Control When There is CT Over Current Protection
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 conrmed and send failure code to indoor. Meanwhile, by controling the max. condensate temp.
Tc (cooling) or TmAVE (heating), please conrm as follow:
In nominal cooling/dry/heating mode, high pressure can be controlled by limiting the max. frequency.

Stop immediately, if abnormal stop 3 times in 1 hour, the
unit will stop and alarm.
