Abstract
An air-handling system for a heating, ventilation, and air conditioning system comprising includes a main housing, a temperature door, a mode door, and a control mechanism. The temperature door is disposed in a mixing and conditioning section of the main housing to control a temperature of a flow of air to a delivery section of the main housing. The mode door is disposed in the delivery section of the main housing to control a flow of air through an upper conduit and a lower conduit. The control mechanism cooperates with each of the temperature door and the mode door. The control mechanism includes a single actuator configured to independently control each of the temperature door and the mode door to provide independent temperature control for each of a high mode, a low mode, and a mixed mode of operation.
