A method for controlling a heating, ventilating, and air conditioning unit is provided. A conditioning unit having a heating stage, a cooling stage, a fan, and an economizer is operated to provide supply air to one or more zones. The temperature of air in the one or more zones and the temperature of air supplied to the one or more zones from the conditioning unit is sensed. At least one of the heating stage, the cooling stage, and the economizer is activated when the sensed temperature in at least one of the one or more zones is outside of a first predetermined temperature range. At least one of the heating stage, the cooling stage, and the economizer is activated when the sensed temperature of the air in the at least one of the one or more zones is within the first predetermined temperature range and the sensed temperature of the supply air is outside of a second predetermined temperature range.
