Abstract
An occupancy sensing system includes a device clock included in an assembly with a device such as a switching device or an occupancy sensor. The device clock enables time tracking functionality to be combined with occupancy sensing to control lighting and other loads. A display and/or interface may be included to enable a user to a set the time-of-day, day-of-week and program and configure the device clock.
