Detail information
11 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.
12 CN2: HEAT1. Pipeline Auxiliary Heater
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 pipeline auxiliary heater.
13 CN85
:
The alarm signal output of the unit (ON/OFF signal)
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 alarm signal output.
