PROBLEM TO BE SOLVED: To provide a control system for heating equipment with a blowing function having a safety mechanism utilizing a time stamp system. SOLUTION: In this control system, a built-in power source for driving a counter circuit built in the heating equipment with the blowing function is put in an output stop state when electric power is supplied from an external power source, and used as a drive power source for the counter circuit when electric power is not supplied from the external power source. The counter circuit counts the lapse of time continuously in a period predetermined from a time-stamped reference date, with electric power supplied from the outside or electric power of the built-in power source as driving voltage, and gives a warning to a display part 15 or regulates the operation of the heating equipment at a point of time when the set time elapses.
