In a device for thermal regulation of an enclosure comprising a temperature-measuring circuit which consists of a resistor bridge, of at least one heat-sensitive element on one bridge arm and of an amplifier, a control signal which is representative of the difference between the measured temperature of the enclosure and a reference temperature is delivered at the output of the amplifier. The absolute value of the control signal is adjusted by a negative feedback loop. A circuit for heating the enclosure is regulated by the temperature-measuring circuit and is constituted by at least one control transistor which delivers an adjustable heating current. The feedback loop of the output amplifier is mounted between the emitter resistor of the control transistor and the inverting input of the amplifier.
