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.
Control signal port of hydraulic model contains terminals for solar energy, remote alarm, 3-way valve, pump,and external heating
source, etc.
