The present invention relates to safety systems for a device for regulating the heating of a volume 2 by heat-carrying gaseous fluid supplied by a heat source 3 with which means 5 are associated in order to bring about circulation of the fluid in the volume. The system is characterized in that it includes means 20 for delivering a first fluid temperature signal, first means 26 for comparing the value of the first signal with first thresholds in order to deliver at their outputs 28 second signals representing the comparison, means 32 for visually displaying the values of the second signals, second means 37 for comparing the value of the first signal with a second safety threshold and delivering a third signal, a controllable relay 41 supplied by the third signal and able to deliver a fourth two-state control signal, means 44 controllable by the fourth signal from a control input 43, these means being able to deliver, on an output 45, a signal supplying means 5 making it possible to bring about the circulation of the heat-carrying fluid in the volume. <IMAGE>
