Abstract
A controller for a plurality of devices of a building control system that operate in parallel to provide a desired capacity of heating or cooling for a building space includes a capacity identifier configured to identify the desired capacity of heating or cooling for the building space. The controller further includes a combination finder configured to generate a list of combinations of devices that can be energized to provide the desired capacity. The controller further includes a combination filter configured to remove any combinations from the list that do not meet one or more requirements. The controller further includes a combination selector configured to select one of the combinations based on at least one of a runtime and a transition count. The controller further includes a signal generator configured to generate control signals in accordance with the selected combination and operate the plurality of devices using the control signals.
