Abstract

PURPOSE: To reduce the number of comparators by providing a multiplexer, selection signal generating part, etc.
CONSTITUTION: The temperature detecting circuit 7 and reference signal generating circuit 8 connected to a thermistor 4 disposed in a refrigerating chanber 3 are connected via voltage comparator 9 and multiplexer 10 to the input signal part 12 and selection signal generating part 13 of an arithmetic unit 11. Then, the output of the temperature detecting circuit 7 and the output of the multiplexer 10 which receives the reference signal from the reference signal generating circuit 8 are compared in a voltage comparator 9 and when both coincides, a coincidence signal is outputted and when the coincidence signal is inputted to the input signal part 12, the temperature display signal corresponding to the temperature reference signal of the channel corresponding to the channel selection signal of the selection signal generating part 13 based on this is outputted from the arithmetic unit 11 and is displayed in a display device 16. Hence, the device necessitates only one compartor.
