There is disclosed a water feed device capable of adding mineral components to for-treatment water in accordance with user’s request to feed a variety of water including the mineral components from soft water to hard water. For this purpose, a theoretical expected value of the resource consumption, in particular of the energy andor water consumption, is calculated, the actual value is determined and from a deviation between the expected value and the actual value a malfunction of the pasteurization installation is concluded. The pawl portion includes a fixed end and the pawl portion is located adjacent to an end surface of the connection port. The multiple drawers allow a user to add wood andor water without opening the smoking chamber. The systems and methods according to this invention allow the number andand or locations of punches andor perforations and the type andor length of folds to be controlled on a sheet-by-sheet basis. The video circuit may further include an input signal detection circuit adapted to generate a third signal indicative of whether an input video signal is present.
