Operating method for optimizing the functionality of professional electric ovens, especially for pizzas, the ovens comprising: - a cooking chamber; - first resistors for heating the floor of the cooking chamber; and - second resistors for heating the roof of the cooking chamber, the method being characterized in that it comprises global computerized self-limitation of absorption of electrical power by the heating means (P,C) of the oven with balanced automatic distribution of electrical power supply depending on the type of product undergoing the cooking process between the first heating resistors for the floor of the oven cooking chamber and the second heating resistors for the roof of the oven cooking chamber, said heating resistors for the floor and for the roof having independent power supply one with respect to each other, wherein upon the occurrence of absorption peaks of electrical power by the resistors exceeding a preset certified calibration maximum oven absorption power, performing a safety disconnection of power by means of independent means dedicated to possible malfunction of the balanced self-limitation, said global computerized self-limitation being actuated and controlled by electronic means integrated by independent safety electromechanical means for disconnecting power absorption should said electronic means for balanced distribution and global reduction fail to perform their functions of power reduction in a balanced fashion between the floor heating means and the roof heating means, said balancing depending on the needs and/or on the initial manual setting referring to the type of product undergoing the cooking process and/or according, possibly self-implementable, to the weighted mean of detections of the corrective actions carried out manually under similar conditions. - a cooking chamber; - first resistors for heating the floor of the cooking chamber; and - second resistors for heating the roof of the cooking chamber, the method being characterized in that it comprises global computerized self-limitation of absorption of electrical power by the heating means (P,C) of the oven with balanced automatic distribution of electrical power supply depending on the type of product undergoing the cooking process between the first heating resistors for the floor of the oven cooking chamber and the second heating resistors for the roof of the oven cooking chamber, said heating resistors for the floor and for the roof having independent power supply one with respect to each other, wherein upon the occurrence of absorption peaks of electrical power by the resistors exceeding a preset certified calibration maximum oven absorption power, performing a safety disconnection of power by means of independent means dedicated to possible malfunction of the balanced self-limitation, said global computerized self-limitation being actuated and controlled by electronic means integrated by independent safety electromechanical means for disconnecting power absorption should said electronic means for balanced distribution and global reduction fail to perform their functions of power reduction in a balanced fashion between the floor heating means and the roof heating means, said balancing depending on the needs and/or on the initial manual setting referring to the type of product undergoing the cooking process and/or according, possibly self-implementable, to the weighted mean of detections of the corrective actions carried out manually under similar conditions.
