)
(b)The thermistor cable are delivered with the unit
:
if the current of the load is large, an AC contactor is needed.
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 page 59 of connection terminal block 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.
