6.2.3 Low pressure protection
In order to realize low pressure protection, the low pressure is controlled by simulating evaporating temperature:
When cooling, compare the evaporating temp. with the compressor suction temp. and choose the lower one (Teva c)
to simulate judgment.

If it lasts 5 seconds, unit will stop and Alarm.
After standing by 3 minutes, unit will restart. If
it happens 3 times in 60 minutes, unit will stop
and alarm for ever. It will disappear if unit back to
power.

When heating, you can judge through comparing defrost temp. (Te) with environment temp. (Tc) and choose the
lower one (Teva h) .
