特徴とする屋上換気扇の駆動制御装置。[Scope of Claim for Utility Model Registration] A moving circuit for moving a moving member for opening and closing an opening for ventilation to an open position or a closed position based on an opening/closing signal from an opening/closing signal transmission circuit, and for exhausting air from the opening. A rooftop ventilation fan equipped with a drive circuit that drives a drive motor of an exhaust fan, and a changeover switch that activates the drive circuit when a moving member moves to an open position makes contact with the drive circuit, and opens the drive circuit when the moving member moves away. The drive control device includes a holding circuit that closes when the changeover switch enables the drive circuit to maintain the enabled state of the drive circuit, and opens the holding circuit when a close signal is transmitted from the open/close signal transmission circuit. A drive control device for a rooftop ventilation fan, characterized in that it is provided with an opening means.
