Claims

[Scope of utility model registration request]

A temperature set value for setting the temperature of the temperature controlled device, and a temperature fluctuation range from the temperature set value used for ON/OFF control to energize/de-energize the operating end of the temperature controlled device. a set value storage means for storing a differential value to be determined, a temperature detection value by a temperature sensor that detects the temperature of the temperature controlled device, the temperature set value read from the set value storage means, and the differential; ON/OFF control output calculation means for determining an ON/OFF control output mode to the operating end based on the serial value and outputting an ON/OFF control output signal to the operating end; In a temperature control device that adjusts the temperature by performing de-energization control, there is provided an allowable differential in which at least the allowable maximum value and allowable minimum value of the differential value are stored in advance as differential value change data. an allencial value storage means, and a start/stop frequency detection means for detecting a start/stop frequency that is the ON/OFF frequency of the ON/OFF control output based on the ON/OFF control output of the ON/OFF control output calculation means. Then, the differential value change data to be stored in the set value storage means is calculated using the differential value change data read from the allowable differential value storage means in accordance with the detection result of the start/stop frequency detection means. 1. A temperature control device comprising differential value changing means for selectively changing the differential value as it is or for executing an operation for changing the differential value.
