Active Switch

Unit used for rainwater management. The unit detects a lack of water in the collection system, whether from rainwater or the mains and makes corrections to ensure proper operation of the plant (that is, it does not ever leave the connected utilities dry). This system is reserved for irrigation, clothes washing, WC flushing and floor cleaning applications. The primary purpose of the Active Switch system is to give use of the rainwater priority over the use of the mains water. When there is not enough rainwater in the collection tank, the control unit switches over to the mains, ensuring that the connected use points are supplied (note the water supplied by this system is not drinkable). The system comprises a polyethylene (PE) tank and Euro Inox 30/50 IE2 centrifugal pump and a Control-D G-Set. The kit includes a wall mount bracket and a water level sensor with 20 meters of cable. The connection between the rainwater collection tank and the mains water collection tank in this system is selected by way of a three-way valve installed on the suction side of the pump.
Pump operation is precisely that of a “start-stop” system with pressure and flow control. When the pressure drops below a certain threshold level, the pump starts up. Upon closing the tap, the pump stops. If the water runs out, the pump stops and signals a fault on the pump control panel. After a set time, the pump starts back up again automatically. If all the functions’ parameters have returned to normal, then the system runs normally.
