VAAN-100 WIRELESS AUTOMATIC WATER LEVEL CONTROLLER Stop tank overflow, reduce dry-run risk and automate your water pump—without running a signal wire between the rooftop tank and controller. VAAN-100 uses patented dedicated wireless technology to communicate between the rooftop Hub and Master Controller. The complete system has been tested up to 1 km line-of-sight and works independently without Wi-Fi, internet, app or SIM. The pump automatically switches ON when the tank level is low and OFF when the tank is full. A dedicated flow sensor checks actual water flow and stops the pump if flow is not detected, helping protect against dry running. The rooftop sensor assembly comes with pre-fitted wiring and tool-free cable-tie mounting, suitable for compatible inlet pipes or adapters up to 2 inches. The Master Controller features a 2-line OLED display showing pump operation, tank level, water flow, Hub battery, AC supply and system alerts. Manual Mode is also available for direct pump control when required. The rechargeable wireless Hub provides up to 6 months of operation per charge under normal conditions and supports convenient USB-C charging. Suitable for 230V AC water pumps up to 1.5HP and designed for homes, independent houses, apartments and multi-floor buildings. Automatic water management without conventional tank-to-controller signal wiring. FREQUENTLY ASKED QUESTIONS Q: Will VAAN-100 work in a multi-floor building? .
