This presentation is used for training of Energy Management Technicians in the purpose, operation, and creation of schedules in Metasys Extended Architecture.

1. Metasys
Schedules
WKU

2. The purpose of schedules
• Allow for automatic occupying of VAVs or AHUs
instead of requiring them to be manually enabled
• Allow for automatic changes to set-points within the
system
• Allow automatic lead lag rotation of pumps, chillers,
etc.

3. Schedule screen automatically displays
todays schedule

4. Scheduled Item
The scheduled item is the point that is controlled by
the schedule.
• Occupancy
• Set Point
• Lead Lag

5. Scheduled Items

6. Schedule Active time
period
• Schedules can be set up to be active for a specific
time period.
• Due to the large number of schedules on our
system, the amount of memory they consume and
constant changes, we do not use this feature.

7. Setting schedule active
time period

8. Display mode within a
schedule
The display mode allows us to select between three
edit screens within a schedule
• Weekly schedule
o Most common used section
o Allows for the setting of normal occupied time for rooms and AHUs
o Allows for setting normal set point values
• Exception schedule
o
o
o
o
o
Special times for a particular date
Special time for a date range
Special time for a certain day of the week
Special time for certain day each month
Set a calendar reference
• Scheduled items
o The item or items being scheduled

9. Display Mode within a
schedule

10. Display Mode Dropdown
Window

11. Weekly Schedule
• Most commonly used for classes and office hours
• Set a weekly occupy and unoccupied times for
VAV’s or AHU’s
• Used for pump or lead lag rotation of components
within the system
• Can be used for set point changes

15. How to build a Metasys
Schedule
The steps involved in building a Metasys schedule
include:
• Creating the schedule object
o Selecting the schedule location
o Naming the schedule
• Linking the schedule to the control point
• Entering the effective time or set point value

16. Creating the schedule
object

17. Creating the schedule
object

18. Selecting a schedule
location

19. Naming the schedule
A schedule should be named something that
associates it with the item it is controlling
• Room number (most common)
• VAV number
• AHU number

20. Naming the schedule

21. Schedule configuration
• It is possible to set up the schedule under the
configuration screen.
• A system blink can cause the loss of data entered
• It is recommended to create the schedule object
and then edit the schedule to enter data

24. Newly created schedule

25. Linking schedule to
control point
• The first step in completing the creation of a
schedule is to link it to the object it controls.
• A schedule writes at priority 15 within the system by
default.
• A schedule priority cannot be set below priority of 9
• It automatically configures schedule parameters
such as the State text

26. Linking schedule to
control point

27. Multiple items in
schedule items list
• It is possible for a single schedule to control more
than one device
• All devices must be of the exact same device type
• The first item in the list is considered the KEY item
which sets schedule state text

28. Multiple items in
scheduled items list

29. Unoccupy all days

30. Entering schedule time
• Un-occupy the entire day for each day the
schedule will be used. This eliminates control issues
we have experienced in the past.
• Enter the occupancy start time
• Enter the occupancy end time

31. Select occupancy days, time,
and state

32. Setting time to unoccupy

33. Exception Schedule
Allows the choice to schedule:
• A certain date
• A date range
• A certain day of the week
• Reference a calendar for a particular day
Exception schedules will ALWAYS override a daily
schedule.
• Remember to include the daily hours whenever
setting up an exception schedule

34. Creating Exception
Schedules

35. Link schedule to calendar

36. Entering exception
occupancy time
