：
Input of three-phase four-wire power supply (fault code E1)
Input of transformer, 220-240V AC current. (only valid for the main unit)
Three phases L1, L2 and L3 of power supply should exist simultaneously, and the difference of phase angle should be
120º among them. If the conditions are not met, fault of phase sequence or phase lack may occur, and fault code will
be displayed. When the power supply returns to normal condition, fault is removed. Attention: phase lace and phase
dislocation of power supply are detected only in the early period after the power supply is connected, and they are not
detected while the unit is in operation.

CN83:COMP-STATE,connect with an ac light to indicate the state of the compressor
Attention: the control port value of the pump actually detected is ON/OFF but not 220-230V control power supply
，
so
special attention should be paid when installing the light.
