Abstract: 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.

Abstract: A hygienic sheet material dispenser includes a housing with a dispensing opening, a compartment for a sheet material product, a first sensor arranged to assume an active mode in which it scans for the presence of a user, a dispensing motor arranged to drive a driving mechanism, a second sensor for sensing when a piece of said product has been removed, and a microcontroller connected to the first sensor, the second sensor and the dispensing motor, said dispenser also being configured to be switched to a passive mode. The dispenser is arranged to switch to the passive mode after a first predetermined period of time has elapsed in the active mode without detection of a user; wherein, upon entering the passive mode, a length of said product is fed from the dispenser out of the dispensing opening and the first sensor and the microcontroller are substantially deactivated; and wherein the dispenser is arranged to switch back to the active mode when the second sensor senses that said product has been removed.
