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.

System and method for controlling an ultraviolet air treatment device for return air duct applications

An application and method for disinfecting HVAC systems that includes features for protecting service personnel from unintended exposure to ultraviolet radiation. The safeguards include an interlock that prevents illumination of germicidal lamps when their enclosure case is not properly attached to a duct.
