CN83: COMP-STATE, connect with an ac light to indicate the state of the compressor
Attention: the control port value of the unit actually detected is ON/OFF but not 220-230V control power supply, so
ˈ
special attention should be paid when installing the light.
CN85
：
The alarm signal output of the unit (ON/OFF signal)
Attention: the control port value of the unit actually detected is ON/OFF but not 220-230V control power supply, so
special attention should be paid when installing the alarm signal output.
