A system and method for controlling operation of an ultraviolet air treatment device including an ultraviolet lamp positioned to treat air within an air handling system that operates in either an on state or an off state. The method includes activating the ultraviolet lamp, and determining the operational state of the air handling system. The ultraviolet lamp is deactivated upon expiration of a predetermined time period during which the air handling system remains in the off state. The predetermined time period is preferably 30-60 minutes, preferably 40 minutes for residential applications.
