What does a scheduling system do?

1. Turns lights on based on occupancy

2. Controls lights according to a preset schedule

3. Dims lights based on daylight

4. None of the above

The correct answer is: Controls lights according to a preset schedule

A scheduling system is primarily designed to manage lighting by operating fixtures according to a predefined timetable. This means it can turn lights on or off at specific times throughout the day or week, ensuring a consistent lighting environment that meets the needs of the space and its occupants. By using a scheduling system, energy efficiency can be optimized, as lights can be turned off when not needed or turned on in anticipation of occupancy, aligning lighting with the actual use of the space. The other functions listed, such as turning lights on based on occupancy or dimming lights based on daylight, often involve more dynamic control methods. While these are valuable features within a broader lighting control system, they do not encapsulate the fundamental purpose of a scheduling system, which is strictly about managing light according to set times rather than real-time conditions or events.
