PURPOSE:To reduce electric power consumption and prevent generation of hunting upon changing a set value in a dream circuit by a method wherein a means to output the set value, set in a temperature setter, after changing it into a predetermined value is provided with a primary delay operation means additionally. CONSTITUTION:In the control device of the air-conditioning machine equipped with a means to output the set value, set in the temperature setter, after changing it into a predetermined value by the operation of a good night timer 7, the primary delay operator 100 is provided. The set value is changed when a time (tc) has elapsed after starting the timer 7 by an operating switch 6, however, the primary delay operator 100 operates the changing process of the set value so that the temperature is changed smoothly in accordance with the change of time. As a result, the hunting of a room temperature due to the change of the set value is eliminated and comfortable feeling during sleeping may be held.
