PATENT Title SUPPLY AIRFLOW CONTROL FOR DUAL-DUCT SYSTEM Inventor Harry Kenneth Ring Abstract Two variable position supply air valves, one for modulating warm airflow to a comfort zone and the other for modulating cool airflow, each have a constant intermediate open position to provide at least a desired minimum airflow, and both can be controlled so that only one valve is open at any one time to minimize any mixing of the airstreams. Potentiometers are used to adjust the intermediate open position of each valve and to adjust at least one valve's relationship of valve opening to zone temperature.
