The KWC ONO Touch Light PRO is an electronic faucet operation with two electronic controls: a permanently mounted device and an optional, portable wireless, touch-operated device with magnet base. Users tap the portable device once for the cold temperature, twice for the warm setting or three times for the hot temperature. The colored light ring designates the selected temperature. It also offers two separate water outlets: a swivel spout and a semiprofessional spray. The fifth component, the mixer itself, usually is concealed below the countertop. KWC
