Interface for an automatic hygienic sheet paper dispenser

An interface for communicating with and for controlling the operation of an automatic hygienic sheet material dispenser, the interface comprising:

• a user sensor arranged to have a sensing zone and to detect the presence of a user within the sensing zone;
• at least one indicator for indicating the setting or status of an operational parameter of the dispenser;
• a main microcontroller;
• at least one additional sensor for adjusting at least one dispenser operational parameter or for activating at least one dispenser function, the at least one additional sensor configured to be actuated to adjust the at least one dispenser operational parameter or activate the at least one dispenser function without physical contact to the at least one additional sensor;
• and
• a protective cover comprising at least one graphical symbol or text,
• wherein the at least one additional sensor, the at least one indicator and the main microcontroller are located on a main printed circuit board, the main printed circuit board being located behind the protective cover and arranged relative to the at least one graphical symbol or text such that (i) the at least one graphical symbol or text overlaps with the at least one additional sensor or the at least one indicator, (ii) the at least one indicator is visible through the protective cover, and (iii) the at least one additional sensor is configured to detect a touch of the at least one graphical symbol or text on the protective cover, and
• wherein the main microcontroller is arranged to selectively operate the dispenser in any of at least a user setting and a maintenance setting.
