6.2 Schedules Reference
The Schedules component of the management platform enables you to:
● Set up schedules to automate the operation of the building control site:
Schedules are defined on a weekly and daily basis. You can specify a different
hourly timetable for each day of the week. For example, you could schedule a
heating system to work from 9 a.m. to 6 p.m. on Mondays and Fridays and
from 8 a.m. to 8 p.m. on Tuesdays, Wednesdays, and Thursdays
● Set up exception calendars, which can be associated to schedules: Calendars
define dates (or date ranges) during which a schedule does not apply. For
example, you could create a holiday calendar that overrides the regular heating
schedule to reduce energy costs. When you create a calendar, you can choose
specific dates (January 15), a date range (August 1 – 31), or a week and a day
you want the exception to run (third week of the month, on Wednesday). Then
you can associate one or more schedules with the calendar.
You can configure schedules and calendars to execute:
● Centrally, on the management platform
● Locally, directly on the BACnet field panel
You can set up multiple schedules and exception calendars to run at the same
time.
6.2.1 BACnet Schedules Reference
This section provides background information for using BACnet schedules. For
related procedures, see Working with BACnet Schedules [➙ 153].
6.2.1.1 Overview of BACnet Scheduling
You use BACnet scheduling to automatically command points at prescribed time
intervals. You can create daily or weekly schedules for BACnet field panels. Each
BACnet panel stores its own calendar and schedule objects, and a BACnet panel
can store and run multiple calendars or schedules at the same time. Because
BACnet schedules reside in and are executed by field panels, they run even if the
management station they are associated with is not running. BACnet schedules
handle only BACnet objects (management station schedules can handle both
BACnet and non-BACnet object types).
You can also configure commands to control BACnet objects related to your
schedules. For example, you want to create a command that turns lights on and
maintains room temperature at 72°F (22.22°C) when the room is occupied. When
the room is unoccupied, the command would turn lights off and maintain the room
temperature at 65°F (18.33°C). In this scenario, you could create a command with
