Patent attributes
The disclosure concerns an interface for communicating with and for controlling the operation of an automatic hygienic sheet material dispenser. The interface includes a user sensor to detect the presence of a user within a sensing zone, at least one indicator for indicating the setting of an operational parameter, a main microcontroller, at least one additional sensor for adjusting a dispenser operational parameter or activating a dispenser function, and a protective cover including a graphical symbol or text. The at least one additional sensor, the at least one indicator, and the main microcontroller are located on a main printed circuit board located behind the protective cover and arranged such that the at least one graphical symbol or text overlaps with the at least one additional sensor or the at least one indicator. The main microcontroller is arranged to selectively operate the dispenser in a user setting or a maintenance setting.
