Powered by patented TIF Touch-free Intelligent Faucet technology and the advanced iSense control system, the Cinaton Touchless 2-Sensor Bathroom Faucet with Temperature Lever combines 2 infrared sensors with intuitive functions to deliver convenient hands-free control for effortless everyday use. The under-spout sensor automatically turns water on when hands are detected and off when they are removed for quick, automatic handwashing. The upper sensor lets you turn continuous water flow on or off by holding your hand near the sensor, without touching the faucet. A sleek integrated side lever lets you easily adjust the water temperature to your preference. Its touch-free operation helps keep the faucet cleaner, minimize the spread of germs and bacteria, reduce cross-contamination, and prevent water waste in both residential and commercial applications. Designed for easy DIY installation, the faucet includes an AC power adapter, a battery backup box with 4 AA batteries for power outages, water supply lines, and mounting hardware.
