NOTE
Please use H07RN-F for the power wire, all the cable are connect to high voltage except for thermistor cable and cable
for user interface.
● 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.
