1.8.10 High pressure switch
3 minutes later after compressor starts up, the system will check the pipe pressure. If the pipe pressure is
over high and high pressure switch acts for over 30 seconds, the compressor and outdoor motor will stop, 3
minutes later, the unit will resume. If in 60 minutes the unit stops for 3 times because of overhigh pressure, the
system will alarm, then compressor will not start up again; when being electrified after being powered off, the
protection will be cancelled.

When compressor works, if low pressure switch acts for 60 seconds contineously, the unti will alarm.
When compressor stops, if low pressure switch acts for 30 seconds contineously, the unti will alarm.
When compressor starts up, in 3 minutes, low pressure switch will be shielded.
In 6 minutes after defrosting is over, low pressure switch will be shielded.
1.8.12 Failure code and troubleshooting
z Alarm lamp is off when no failure, flash when failure occurs, the different flash time means different
failure.
Ensure that alarm indicating time is over 2 minutes and 50 seconds.
1˅Indoor pipe temp. is abnormal, outdoor default cooling temp. : 5ć, heating temp.: 40ć. The above
temperatures are normal.
2˅In defrosting, and in 3 minutes after defrosting is over, if sensor is abnormal, there will not alarm.
3˅Outdoor defrosting temp. sensor: when ambient temp. is below -5ć, detect after having start for 3 minutes.
