Abstract
A method includes, at a start time, controlling a cooling unit to start the cooling unit in a mechanical mode and controlling the cooling unit to transition, after waiting a waiting interval from the start time and over a transition interval, the cooling unit from the mechanical mode to an economizer mode. In the mechanical mode, the cooling unit receives return air, cools the return air, and releases the cooled return air as supply air. The supply air is air supplied to a cooled volume. In the economizer mode, the cooling unit receives outdoor air and releases the outdoor air as at least a portion of the supply air. Transitioning the cooling unit from the mechanical mode to the economizer mode includes transitioning, over the transition interval, from receiving only the return air to receiving progressively less of the return air and progressively more of the outdoor air.
