Abstract
A method and system for controlling a heating, ventilating, and air conditioning unit is provided. The system includes a conditioning unit having a heating stage, a cooling stage, and a fan. The conditioning unit operates in an active mode where one of the heating stage and the cooling stage is activated to condition air in an enclosure. The conditioning unit also operates in a ventilation mode to provide supply air to the enclosure. A supply temperature sensor is provided to sense the temperature of the supply air. A central control operates to activate one of the heating stage and the cooling stage when the conditioning unit is operating in the ventilation mode and the temperature of the supply air is outside of a predetermined range.
