Abstract: A method of operating a cooking zone (2) of a cooking appliance (1). The method includes determining an actual temperature value representative of an actual temperature of an item (6) to be heated; determining a power level (I) set on a user control device (3); and calculating a rectified power level (II) based on the actual temperature value, the actual power level (I) and a preset setpoint temperature. The rectified power level (II) is configured to remove differences between the actual temperature value and setpoint temperature and the rectified power level (II) is indicated on a user display (9, 4).

Abstract: A gas burner (2) including a gas injector (3), a gas supply line (4) connected to the gas injector (3) so as to feed gas to the gas injector (3), and a single automatic gas valve (5) installed in the gas supply line (4) upstream the gas injector (3) so as to control gas supply to the gas injector (3). During ordinary operational modes, the single automatic gas valve always is in an open status not exceeding a preset upper opening limit. During temporary boost operational modes the automatic gas valve is in an open state exceeding the upper opening limit.

Abstract: A method of operating a domestic cooking hob (1, 3), wherein the cooking hob (1, 3) includes a user control interface (4) adapted to inputting user control information for controlling operation of the cooking hob (1, 3). The cooking hob (1, 3) is operable in a safety locked operational mode. In the safety locked mode, the cooking hob (1, 3) triggers a safety action in case that a person tries to operate the control interface (4) without unlocking the cooking hob (1, 3) or a person comes closer to the cooking hob (1, 3) than a preset distance without unlocking the cooking hob (1, 3).
