Abstract

PURPOSE: To make it possible for one temperature detector to control the temperature of an equipment which is to be brought under temperature control, without reference to whether CPU is in normal operation or not, by providing a backup control circuit, comparing the value of the temperature detector with a temperature set value, in parallel to CPU.
CONSTITUTION: When CPU1 is in normal operation, the value of temperature setter 6 and that of temperature detector 3 are fetched and refrigerating-heating source driving circuit 2 controls refrigerating-heating source 4 of an equipment whose temperature is controlled. If CPU1 is not in normal operation, the fault is detected automatically and backup control circuit 7 permits temperature setter 6 and temperature detector 3 to control circuit 2, thereby controlling refrigerating-heating source 4. The temperature controller consisting of setter 6 and circuits 2 and 7 is arranged at the side of the equipment whose temperature is controlled. Thus, its temperature is controlled by CPU1 in normal operation or by only the temperature controller when CPU is not in normal operation.
