Abstract
A method of controlling an ultraviolet air treatment device including an ultraviolet lamp positioned to irradiate an air conditioner cooling coil. A controller is connected to the ultraviolet air treatment device to dictate activation and deactivation of the ultraviolet lamp. A first control sequence is performed to automatically cycle the ultraviolet lamp between a powered on condition for a first predetermined time period and a powered off condition for a second predetermined time period. In one preferred embodiment, the method further includes monitoring an operational mode of the air conditioner. A transition routine is initiated upon determining that the operational mode has switched from cooling to non-cooling, and the ultraviolet lamp is controlled in accordance with a second control sequence if the air conditioner remains in the non-cooling mode throughout an entirety of the transition routine.
