ABSTRACT:
A method for controlling a temperature of an object to be cooled or heated by a cooling/heating apparatus is improved in that when all of a plurality of temperature detectors for detecting a temperature of the object are operating normally, the cooling/heating capacity of the cooling/heating apparatus is regulated in response to input signals consisting of the detection temperature of the respective temperature detectors according to an operation pattern set in a normal time thermostat. When it has been determined that a certain temperature indicated by a detector is abnormal, then the cooling/heating capacity of the cooling/heating apparatus is regulated in response to input signals consisting of the detection temperatures of the other normal temperature detectors according to an operation pattern set in an abnormal time thermostat that is different from the operation pattern set in the normal time thermostat; thus the temperature of the object can thereby be controlled.
