Function and use of Tank Full Switch

With a Tank Full Switch, the pump works autonomously, saving you time and effort.

The Tank Full Switch is a useful accessory to use with tanks. A float switch detects the level of water in a tank or container.

It floats on top of the water surface and functions as a mechanical switch as the water level goes up or down.

When the tank is full, the accessory sends a signal to the controller to turn the pump Off. When the tank is empty, the switch sends a signal to the controller to restart the pump and fill the tank.

Connection to the controller

The Tank Full Switch accessory connects to the controller input socket marked with the following symbol, which is printed on the housing of the controller.

Remove the protective cap from the controller’s input socket.

Take the cable with the Tank Full Switch connector and make sure the pins are properly aligned with the controller socket.

Screw the connector in firmly until it stops turning.

Below is a video showing how to correctly connect the accessory to the controller. (This video shows the S1-200 controller, the connection also applies to the S1-700 controller)

The Tank Full Switch accesory can be activated in two ways:

Using the S-Connect application (with a Smartphone or tablet) or
