Abstract: A building commissioning system includes a controller and an electronic database for storing a building layout that includes desired locations for devices to be mounted in a building. The system includes a portable wireless unit with a display for use by an installer. The display on the portable wireless unit shows a graphical representation of the building layout for an area selected by an installer to illustrate desired locations for devices, such as lighting fixtures and wall switches, to be installed in the building. Upon installing a device at the desired location, an installer obtains a unique identifier for the installed device that is matched with the corresponding installed location. The unique identifier and the installed location are sent to the controller for storage in the electronic database. The stored device and location information enable a user to control or adjust device operations.

Abstract: Systems and methods are described for selectively applying DC power from a variable voltage DC power bus to a DC load. The ballast includes at least one switch coupled between the DC power bus and the DC load. A processor is coupled to the at least one switch and controls the operation of the at least one switch. A non-transient computer-readable memory stores instructions that are executed by the processor to control the operation of the processor. The processor determines a voltage on the variable voltage DC power bus and defines a pulse-width modulate power control signal based on the determined voltage. The at least one switch is then operated based on the pulse-width modulated power control signal to apply DC power from the DC power bus to the DC load at a first frequency.
