A timeclock is an example of what type of lighting control?

1. Photocell control

2. Scheduling control

3. Dimming control

4. Motion detection control

The correct answer is: Scheduling control

A timeclock is categorized as a scheduling control because it is specifically designed to turn lighting systems on or off at predetermined times. This type of control allows for efficient regulation of lighting based on a set schedule, which can be particularly useful for managing energy consumption and ensuring that lights are activated only when needed. In contrast, photocell controls respond to ambient light levels, dimming controls adjust the intensity of light, and motion detection controls activate lighting based on the presence of movement in a designated area. Each of these alternatives serves distinct functions relating to lighting management, but they do not provide the time-based scheduling capability that a timeclock does. Thus, the association of a timeclock with scheduling control highlights its role in facilitating planned lighting use for efficiency and convenience.
