· When unit stops, the reason that system still checks the low pressure : in a long time stop, make

protection for the compressor on the condi tion of great refrigerant leakage.

· The reason that low pressure switch action time is 30 seconds: when compressor stops, low pressure
does not change, so it will be shorter than the set time in operation.
(3) When compressor starts up, in 8 minutes, low pressure switch signal will be shielded.
(4) In defrosting, low pressure switch will be shielded.
(5) In oil return procedure, low pr essure switch will be shielded.
(6) In the refrigerant discharging procedure after the oil return in cooling is over, low pressure switch will
be shielded.
In  addition,  the  system  will  control  low  pressure  through  the  evaporator  temp.  TE  to  realize  the  low
pressure protection function.
In cooling, confirm through Tc2AVE:

In heating, confirm through defrosting temp. Te:

If the failure is not confirmed as the permanent protection, outdoor will not send failure code to indoor, and
indoor will not alarm.
