Abstract
An intense field dielectric air filtration system associated with an air conditioning unit includes a microprocessor based control system which may be connected to the thermostat of the air conditioning unit to energize the air filtration system in response to a call for heat or cooling signal at the thermostat or startup of the fan motor for the air conditioning unit. The control system includes a power supply for the air filtration system together with voltage and current monitoring circuits for detecting a fault condition. Filtration system on/off and timing function reset switches are connected to the microprocessor and visual displays, including a multicolored LED bargraph display, are controlled by the microprocessor to indicate voltage potential applied to the air filtration system, a fault condition or a test mode.
