Abstract
A method is provided for managing the energy usage of an energy consuming system adapted to determine the energy of a controlled space, the energy consuming system including a plurality of operating components having on and off states and a plurality of differing noise levels when making transitions between the on and off states. The method includes determining the noise levels of the components of the energy consuming system, selecting a relatively low noise level component of the energy consuming system to provide a selected noise masking component, and causing a relatively high noise level component of the energy consuming system differing from the selected noise masking component to make a transition between on and off states. The method further includes causing the selected noise masking component to make a transition between its on and off states after the transition of high noise level component. The noise level of the selected noise masking component prior is increased prior to the transition of the high noise level component and decreased thereafter. The noise level of the selected noise masking component is gradually increased and gradually decreased. The operations are p…
