ABSTRACT:
An improved temperature control device which is so arranged that, by obtaining an average value of digital output amount of an A/D converter, if variation of the above digital output amount average value at each sampling is within predetermined dead zone data, it is regard that there is no change, while on the other hand, if the above variation is larger than the dead zone data, control is effected on the assumption that variation has taken place by the amount obtained by removing the dead zone data from the amount of the variation.
