<p>PURPOSE:To control always the temperature with less overshoot and ripple components, by setting again the temperature at a controlling point with an initial temperature near a control object and controlling turn-on and off. CONSTITUTION:When the initial temperature of the controlling object is detected by a temperature detector 1, a storage circuit 4 stores the temperature at the controlling point based on the detected temperature by the output of a pulse generator 3 at the power-on time for power supply. The time of a program timer 5 is determined by this signal, and the signal of a pulse generator 6 is inputted to an AND circuit 7 by the operation of the timer 5. At this time, since an on-off controller 2 is set so as to issue the output until the temperature becomes a set temperature, turn-on and off of a switching element are controlled from the temperature at the controlling point to the set temperature. Thus, the temperature is always controlled with less overshoot and ripple components.</p> |
