|Title:||AUTOMATIC TUNING DEVICE|
For a cascade control, the present invention is provided with: an elapsed time measurement unit 6 which performs a process of monitoring the temperature of a control target and detecting a timing at which the temperature of the control target passes a set temperature, and measures an elapsed time from a previous passing timing to a current passing timing; and a time calculation unit 7 which calculates an end time of automatic tuning by using the elapsed time measured by the elapsed time measurement unit 6, wherein a time presenting unit 8 displays the end time of automatic tuning calculated by the time calculation unit 7. Accordingly, for the cascade control, a user can know the end time of automatic tuning.
