EcoSmart - the plug & play feed console
GRAF EcoSmart is the smart system control of your rainwater harvesting system. The electronic control unit checks and regulates the entire operation. When the rainwater tank level is low or becomes empty, GRAF EcoSmart automatically switches to mains water supply until the rainwater tank is replenished, when it automatically switches back to rainwater supply. This ensures that a minimum of mains water is used during longer dry periods.
