3.5 Protection Control
3.5.1 Low Pressure Protection Control
Figure 3-5.1: Low pressure protection control
When the suction pressure drops below 0.14MPa the system displays P03 protection and the unit
stops running. When the suction pressure rises above 0.3MPa, the compressor enters re-start
control.
3.5.2 High Pressure Protection Control
This control protects the compress from the over-high refrigerant system pressure.
Figure 3-5.2: High pressure protection control
When the discharge pressure rises above 4.5MPa the system displays P02 protection and the unit
stops running. When the discharge pressure drops below 3.5MPa, the compressor enters re-start
control.
3.5.3 Discharge Temperature Protection Control
This control protects the compressor from abnormally high temperature.
