A cooking appliance includes an oven cavity, an electric heating system having a plurality of electric heat loads for heating the oven cavity, and a controller. The controller includes a memory module having stored therein at least first and second control algorithms for operating the electric heating system based upon an available current supply. If the cooking appliance is connected to a low current rated circuit, the controller will operate according to the first control algorithm and cycle activation of the plurality of heat loads in a manner not to overload the available current supply. Conversely, if the appliance is connected to a high current rated circuit, the control unit will operate according to the second control algorithm and enable activation of multiple heating loads simultaneously. Preferably, the appliance includes a switch or sensor for toggling between the first and second control algorithms.
L'appareil de cuisson comprend une cavité de four, un système de chauffage électrique doté de plusieurs charges calorifiques électriques pour chauffer la cavité du four, et un régulateur. Le régulateur comprend un module de mémoire dans lequel sont stockés au moins deux algorithmes de régulation du circuit électrique, en fonction de la source d'alimentation disponible. Si l'appareil de cuisson est branché à un circuit à faible intensité, le régulateur fonctionnera selon le premier algorithme de commande et actionnera de façon cyclique les charges calorifiques de façon à ne pas surcharger l'alimentation en courant. Inversement, si l'appareil est branché à un circuit à haute intensité, le régulateur fonctionnera selon le second algorithme de commande et actionnera plusieurs charges calorifiques simultanément. De préférence, l'appareil doit comprendre un commutateur ou un capteur qui permet de commuter entre le premier et le second algorithme de commande.
