A stove for burning in electronic modules which incorporate a heatsink to radiate heat comprises for each module controlled electrical power supply circuits and locally controlled temperature regulators employing a controllable dissipator comprising a heat shunt. The heat shunt comprises a heat conducting body, an arrangement for placing the heat conducting body in contact with the heatsink of the module so that they cooperate thermally as a result of the resulting conduction of heat by contact, an arrangement for heating the heat conducting body and a heatsink adapted to dissipate heat from the heat conducting body to an external environment. The dimensions and the geometry of the heatsink of the shunt and the temperature and ventilation conditions of the external environment are adapted to enable a quantity of heat to be extracted from the shunt by its heatsink which is greater than the quantity of heat dissipated by the heatsink of the module. A device is provided for measuring the temperature of the module. A control system for the heating device is adapted to operate in response to a signal delivered by the temperature measuring system so as to apply to the shunt a quantity of heat enabling heat to be input to the module or removed therefrom. The oven further comprises, for all modules, a centralized control unit supervising through a network the operation of the various modules and their associated locally controlled temperature regulators.
