Equipment must be grounded.
All high-voltage external load, if it is metal or a grounded port, must be grounded.
All external load current is needed less than 0.2A, if the single load current is greater than 0.2A, the load must be controlled
through AC contactor.
AHS1" "AHS2", "A1" "A2", "R1" "R1" and "DTF1" "DTF2" wiring terminal ports provide only the switch signal.
Please refer to image of 9.7.6 to get the ports position in the unit.
Expansion valve E-Heating tape,Plate heat exchanger E-Heating tape and Flow switch E-Heating tape share a control port.
