## Schedules Using schedules, your equipment can maintain one set of setpoints during occupied periods to provide comfort, and it can maintain a different set of setpoints during unoccupied periods to reduce energy consumption. Schedules are a WebCTRL® system's most effective cost-saving strategy. You can apply a schedule to a tree item or to a group of tree items.
| When you apply a schedule to a tree item, the schedule affects equipment at and below the area or equipment where the schedule was added.
| When you apply a schedule to a schedule group, the schedule affects all pieces of equipment in the group. For example, a school board meets every third Tuesday of the month and uses the lobby, main conference room, break room, and restrooms. You can create a schedule group to control these different areas with a single schedule.
NOTES When multiple schedules affect a tree item, the net result is the Effective schedule. Do not include preheating or precooling time in your schedules. Optimal Start, another cost-saving strategy, automatically calculates and controls precise preheating and precooling routines. If you are using hierarchical servers, when you add or change a schedule on the parent server, the schedule is automatically downloaded to the corresponding location on the child server(s). If your system has no need to run schedules, you can turn off this feature. First, delete any existing schedules. Then go to the System Settings > General tab, and check the box Disable Schedules feature.
