Overload Protection Water Pump Controller AC Digital Signal Detection Function

Automatic water pump controller

The automatic pump controller is simple and efficient. When the pump is started to pump water, it is often forgotten to shut it down, resulting in waste of electricity and water. The installation of the fully automatic pump is simple and efficient to solve the start and stop of the pump. When the pool is filled with high water level, the pump water supply is stopped by the sensor signal. When the pool is at low water level, the sensor signal starts the pump to pump water.

The automatic water pump controller adopts digital core with overload, no load and ultra low voltage protection. The upper and lower levels and pressure are automatically controlled in one.

Can be connected to float control, pressure gauge control and probe sensor control

Model Description

Installation and wiring connections

(1) There are three hooks at the back side of the controller, please fix it on the wall or in the control
cabinet. Open the terminals box, and connect the power supply and pump correctly.
(2) Connect the probes wires correctly, please note, the probe wires cannot be short-circuited, the
probe wires cannot connect to the wall of the pool, to extend the probe wires, it is suggested the
section area of the extension wires less than 0.75mm2, and please use the waterproof adhesive
tape to make the joint connected well.

Wiring connection for upper pool water level control

When the water level is lower than the middle level, the controller will start the pump, and it stops
while reach to the high level, the low level probe is used to make a close-loop circuit.
