CN33: COMP-STATE,connect with an ac light to indicate the state of the compressor
Attention: the control port value of the COMP-STATE actually detected is ON/OFF but not 220-230V control power
supply, so special attention should be paid when installing the light.
17
CN2
HEAT1.Pipeline Auxiliary Heater
HEAT2: Water tank Auxiliary Heater
Attention: the control port value of the HEAT1 and HEAT2 actually detected is ON/OFF but not 220-230V control
power supply, so special attention should be paid when installing the pipeline and water tank auxiliary heater.
18
CN24
:
