FIELD: electrical engineering. SUBSTANCE: procedure specifically refers to controlling temperature of electric heating devices, such as electric irons, teakettles, grills, vulcanizers, ovens, etc. According to invention resistance of heating element is measured when control unit breaks for certain time period key element, some values of resistance are selected in certain time intervals and obtained data are converted to temperature of heating element. Control unit switches on and off key element with definite duty factor in cycles of power supply to heating element depending on sign of comparison converted temperature and required temperature and needed transfer characteristic. EFFECT: reduced usage of materials for manufacture of electric heating devices, enhanced functional reliability of control units of electric heating devices. 3 dwg
