US Patent 8214085 Ventilator control optimizer

A ventilator control optimizer allowing the control of a ventilator without the need for manual input. The ventilator control optimizer analyzes trends in indoor environmental conditions (dew point, relative humidity, etc.) and makes decisions based on these trends. The ventilator control optimizer is able to change ventilator fan speeds depending on the detected trends. This will prevent the ventilator from operating under conditions which might aggravate the humidity problem indoors. The ventilator control optimizer also allows auxiliary systems (dehumidifier, etc.) to be controlled automatically to deal with high humidity conditions.
