PROBLEM TO BE SOLVED: To ensure comfortable warming suitable for sleep by eliminating the noise and the feeling of air flow. SOLUTION: When switching the operation to a 'sleep' mode, the room temperature is set at a specified temperature +αdeg.C for a predetermined time and then it is set at a specified temperature +βdeg.C (α>β) for next predetermined time. Subsequently, the room temperature is set at a specified temperature. 'Weak air supply' is performed when the room temperature drops below the set temperature while 'air supply stop' is performed when the room temperature exceeds the set temperature by some level and 'intermediate air supply' is performed when the room temperature drops the set temperature by some level.
