PURPOSE: To obtain an optimum time of advance time which causes room temperature to reach set temperature at reserved set time even if there is difference in load due to installation condition, etc., in an entry timer operation of air conditioner.
CONSTITUTION: An advance time is obtained based on the sum of value obtained from the difference (b) between set temperature and room temperature by an advance time reference value operation using entry timer reserve (a) and correction value (d), and when said time has exceeded an entry timer reserve set remaining time, operation is started at a constant rotational speed (f). Thereafter control input of correction value (d) is prepared by Fuzzy operation (j) using data when the room temperature has reached the set temperature before an entry timer reserve set time (h) and data when the room temperature hasn't reached before said set time (i), and said control input is added to existing correction value (d) so that said correction value (d) is incorporated into next advance time.
