| Summary: | A method, system, apparatus, and device to provide an effective, automatic means to effect exhaust, supply, or balanced ventilation, or a combination thereof, by automatically activating a ventilation fan for the selected operation time per cycle interval based on prior fan operation due to automatic cycle operation and user demand. In a second embodiment the ventilation fan controller automatically activates said ventilation fan in conjunction with operation of a blower of a central air conditioning system. In a third embodiment, the ventilation fan controller also automatically operates the blower for the selected operation time per blower cycle interval, including operation due to thermostat and/or humidistat demand and operates the ventilation fan in conjunction with operation of the blower and/or for the minimal time selected per interval, including operation due to user demand. Optionally, a position of an outside air intake damper is controlled in conjunction with activation of the blower. |
