Title
(EN) SYSTEMS AND METHODS TO DETECT HEATER MALFUNCTION AND PREVENT DRY BURNING
(FR) SYSTÈMES ET PROCÉDÉS POUR DÉTECTER UN DYSFONCTIONNEMENT DE CHAUFFAGE ET EMPÊCHER LA COMBUSTION À SEC
Abstract
(EN) A heater (300) is provided. The heater (300) can be configured to set off an alarm when a heating element (320) is broken or malfunction. The heater (300) can also be configured to connect the heating element (320) to a relatively low voltage when the heating element (320) may experience a dry burning condition.
(FR) On décrit un dispositif de chauffage (300). Le dispositif de chauffage (300) peut être configuré pour déclencher une alarme lorsqu'un élément chauffant (320) est cassé ou en dysfonctionnement. Le dispositif de chauffage (300) peut également être configuré pour raccorder l'élément chauffant (320) à une tension relativement basse lorsque celui-ci (320) se trouve dans une situation de combustion à sec.
