The invention relates to an electronic manager for bread dough mixers and to an operating method. The invention consists of an integral module (15) comprising a PLC (2) which, by means of relays (3, 4 and 5), controls a low-speed contact (8), a high-speed contact (9) and an electrovalve (10, 10′) in order to operate a mixer (14). In addition, the PLC (2) controls a temperature sensor (6), a flowmeter (7, 7′) and a visual and audible indicator (13). The corresponding method comprises a parameter definition step, a start confirmation step, an oxygenation step, a liquid metering step, a mixing step and a return-to-rest step.
