Beschreibung
Zusammenfassung:	A temperature control apparatus for electric heating equipment which can keep the temperature of the load of various heating equipment in substantially constant, and the electric power for heating consumed in vein can be eliminated to save the energy therefor. The apparatus of the present invention for electric heating equipment comprising: a SSR 5 included in an AC line 4 connected between an AC power supply 2 and the electric heating equipment 3; and a CPU 6 for outputting control signals to the SSR 5 for switching the relay, wherein the SSR 5 continuously outputs an input AC voltage fed from said AC power supply, or alternatively outputs the input AC voltage intermittently by cutting one cycle of waveform from the waveform of the input AC voltage, and wherein the temperature control of the electric heating equipment 3 is effected by controlling the apparent frequency of the input AC voltage to be supplied to the electric heating equipment through adjusting the interval of the waveform.
