1 Overflow Detection Function: The default wiring is water ingress detection. If you want the overflow detection function. What you need to have power on the alarm output terminals, the C terminal on the pump output and the C terminal on the alarm output need to be connected. Then connected them with a wire. Next you have the overflow working properly as described in the documentation, the black wire from the sensor needs to be moved and connected to the blue terminal together with the blue wire. 2 Intelligent Control: When the liquid level of the container is too low, the low liquid level alarm signal from the low liquid level sensor is triggered to trigger the controller to close the relay to start the water pump to add liquid level. When the liquid level reaches a certain height, the high liquid level sensor sends a signal to trigger the controller to disconnect the relay to automatically stop the water pump. You can use the controller to either to fill or empty a tank. 3 Non Contact Induction Probe: Water level controller adopts non contact capacitance induction technology and special induction control chip design, the probe is durable, strong anti interference ability, sensitive induction, no contact with liquid, corrosion resistance, safety, environmental protection and no pollution. 4 Wide Voltage Power Supply: Relay dry contact output, the controller can be applied to a variety of load. With Control diversification, water level controller can control the pump in manual or automatic mode. 5 Easy to Install: The installation is simple and convenient. Water level controller can be screwed and installed, also can be installed on the electrical box track.
