となる。As detailed above, this invention provides two types of capacity for the heater that heats the heated object, large and small, and also allows the set value of the temperature controller to be switched between a value lower than the reference value and a value lower than the reference value. When heating, set the set value to the low temperature side, heat with a large capacity heater, and when the temperature approaches the reference value, switch the set value to the reference temperature side, heat with the small capacity heater, and maintain a constant temperature. Since the temperature is controlled, the accumulated heat of the heater that operates near the reference temperature is small, so the influence of the time lag of temperature controller operation is small, and the temperature amplitude is small near the point where the heated object reaches the specified temperature, making it possible to achieve high accuracy. Temperature control can be performed, and even if there are two temperature set points, one temperature regulator can be used, so costs are reduced.
また、大容量ヒータのオン、オフは、加熱時に1回で、
例えば1日に1回スイッチをオン、オフすればよく、液

チのみくり返しオン、オフ動作するので、接点寿命が長
く保てる利点がある。In addition, the large capacity heater can be turned on and off only once during heating.
For example, it is only necessary to turn the switch on and off once a day, and when the liquid temperature is maintained at the reference temperature, only the switch for the small capacity heater is turned on and off repeatedly, which has the advantage that the contact life can be maintained for a long time.

操作ミスにより片一方の調節器の温度設定のみしかしな
い場合等、使用上、構成上程々の問題があるが本考案の
如く1つの温度調節器の設定値を切換えて使用すること
により、上述のような不具合は起らず制御装置全体とし
ての使用が容易になる。When using two temperature controllers and setting each one separately, there are some problems in usage and configuration, such as when only one temperature controller is set due to an operational error. By switching and using the set values of the two temperature controllers, the above-mentioned problems do not occur and the control device as a whole becomes easier to use.
