Abstract

En styreenhet og en fremgangsmåte for å hindre tørrstart av en elektrisk vannvarmer (A) sørger for aktivering av et nedre varmeelement (D) i en kort tid, og avføler deretter temperaturen for å detektere fravær eller nærvær av vann rundt det nedre varmeelement. Ved fravær av vann hindrer styreenheten (E) ytterligere aktivering av varmeelementet. Dersom vann er til stede, aktiveres det nedre varmeelement (D) for å varme opp vannet til en settpunkttemperatur. Et ytterligere, øvre varmeelement (C) kan aktiveres først etter at dets temperatur faller et forutbestemt beløp under settpunkttemperaturen. Styreenheten (E) kan også omfatte en programmerbar tidsbryter med evne til å variere den innstilte utkoplingstemperatur på en forutbestemt måte ved forskjellige tidspunkter av en gitt dag og/eller uke, så vel som å tilveiebringe en bekvem måte for å opprettholde en redusert innstilt utkoplingstemperatur i en lengre tidsperiode.A control unit and method for preventing the dry start of an electric water heater (A) provide for activation of a lower heating element (D) for a short time, and then senses the temperature to detect the absence or presence of water around the lower heating element. In the absence of water, the control unit (E) prevents further activation of the heating element. If water is present, the lower heating element (D) is activated to heat the water to a set point temperature. An additional upper heating element (C) can be activated only after its temperature drops a predetermined amount below the set point temperature. The control unit (E) may also comprise a programmable timer with the ability to vary the set switch-off temperature in a predetermined manner at different times of a given day and / or week, as well as to provide a convenient way to maintain a reduced set switch-on temperature. a longer period of time.
