Wired Controller
Port provide the control signal to the load. Two kind of control signal port:
Type 1: Dry connector without voltage.
Type 2: Port provide the signal with 220V voltage. If the current of load is <0.2A, load can connect to the port directly.
If the current of load is >=0.2A, the AC contactor is required to connected for the load.
WIRING: transfer board/13 to 40 connection priority.
Control signal port of hydraulic model : The XT6-XT9
contains terminals for solar energy, remote alarm, 2-way
valve, 3-way valve, pump, booster heater and external
heating source, etc.
The parts wiring is illustrated below:
1) For solar energy kit
