Abstract: A control system for the operation of a kitchen oven comprising a cooking chamber (11) lodging a heat source (20) and a temperature sensor (30); and a thermostatic control device (40) for controlling the energy supplied to the heat source (20) as a function of a selected operating temperature and of the temperature sensed by the temperature sensor (30). The control system further comprises a decoder (50) for producing a digital signal for each temperature of a scale (45) preset in the thermostatic control device (40); and an electronic control module (M) comprising a processing unit (60) and an audible alarm (80). The processing unit (60) receives from the decoder (50) and processes a digital signal indicative of the activation of the oven and of the operating temperature selected in the thermostatic control device (40), in order to activate the audible alarm (80) when a pre-established initial heating time has elapsed, so that the cooking chamber (11) reaches the selected operating temperature.
