The circuit controls the electronic pump and blow motors with the air pressure sensor locating near to the fuel nozzle and detecting signals for maintaining the desired temperature corresponding to every temperature control step. The circuit includes a power unit (3) connecting to an electronic pump controller (8) through a diode (D3) and a Zener diode (8) for providing the power to condensors (C2) , (C3) and regulator (RE), an oscillator (2) including oscillator element connecting to condensors (C4), (C5) and a registor (R1). an interrupt generating circuit (4), and a display (15).
