とする温度調和装置。 A temperature conditioning device that performs temperature adjustment so that the load temperature becomes a desired set temperature by supplying power, comprising: a resistance element that detects the load temperature; a variable resistor that adjusts the set temperature to a desired value; a comparator that inputs a DC voltage divided according to a change in the resistance value of the resistor to one input terminal, and inputs a DC voltage divided according to the change in the resistance value of the resistor element to the other input terminal; The present invention is characterized by comprising a feedback circuit that supplies the output of the comparator to one end point of the variable resistor, and a control means that controls switching of the power supply based on the output of the comparator. Temperature conditioning device.
