When a plurality of sensors or a circuit, required for air conditioning, are out of order a fail-safe calculation formula is employed to set the desired outlet air temperature for continuing air conditioning. A number of fail-safe calculation formulae exist so that an accurate outlet air temperature can be obtained despite any abnormal sensor conditions. When an abnormality is detected, the calculation formula which does not employ the output of the abnormal sensor is utilized to determine the outlet air temperature. This procecure permits an air conditioning apparatus to be controlled within a range of safety even when a sensor or sensors fail.
