PURPOSE: To make it possible to switch over smoothly with unpleasant feeling suppressed by adding the correction of a specified value to the value of sensed temperature by a first temperature sensor when switching over to the value of sensed temperature detected by a first temperature sensor which detects the temperature of the upper side of an air-conditioned room from the value of sensed temperature by a second temperature sensor provided on a remote controller.
CONSTITUTION: When the signal transmitted from a remote controller 4 does not reach a reception section 7, the value TR of sensed temperature which was last received is stored, and when 10min are counted, 'TA=TB-TR' is sought, where TB is the detected temperature by a first temperature sensor 6 which detects the temperature of the upper side of an air- conditioned room. At this time by bringing this value of the sensed temperature close to the temperature of the lower side of the air-conditioned room 1, the value of sensed temperature by the first temperature sensor 6 is corrected by the addition of TA, and the variation in the values of sensed temperature is suppressed. Accordingly a temperature which is the subject of temperature control suppresses the variation in temperatures when switching over from the value of sensed temperature detected by a second temperature sensor incorporated in the remote controller to the value of sensed temperature by the first temperature sensor to provide a temperature control without giving unpleasant feeling.
