Abstract:
1. A method for controlling at least one heating element of a heating device, comprising at least one electric temperature sensor for measuring a temperature of the at least one heating element or a temperature of a surface heated by the at least one heating element and for controlling an automatic switching off or switching back on of the at least one heating element when a switching criterion in relation to a temperature measured by the at least one electric temperature sensor is reached or the temperature measured by the at least one electric temperature sensor reaches the switching criterion, wherein the switching criterion is generated in a logic device or controller and the switching criterion is a temperature threshold value (T s ) or a temporal gradient of the threshold value which is generated dynamically by specific parameters of the at least one heating element, the switching criterion comprising the following steps: (a) when the temperature measured by the at least one electric temperature sensor exceeds a pre-defined critical temperature, a timer function is started, which after expiration of a pre-defined time period, causes a decrease of the temperature threshold value (T (b) dynamic generation and changing of the temperature threshold value (T
