Abstract (en)
[origin: EP0666482A1] The method involves using an electronic controller, a sensing device with a radiation source and an optical sensor and a valve arranged in the water flow. The controller holds the valve in its instantaneous state when the sensing device is covered, e.g. by hand. The controller switches into a "sleep mode" when the sensing device is covered. After a predefined time following the covering of the sensing device, the controller automatically closes the valve.
