NOTE:
3.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
.
1.Equipment must be grounded. 2.All high-voltage external load, if it is metal or a grounded port, must be grounded.
4.AHS1" "AHS2", "A1" "A2", "R1" "R1" and "DTF1" "DTF2" wiring terminal ports provide only the switch signal. 5.Expansion valve E-Heating tape,Plate heat exchanger E-Heating tape and Flow switch E-Heating tape share a
control port.
6.WIRING: transfer board/13 to 40 connection priority
