return to the weekly schedule at 2 P.M.

7.4.2 BACnet Calendars

Calendars allow you to override a scheduled event. In this sense, you can consider

them as exception schedules, consisting of dates only. 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). All calendars are associated with a schedule. If you want to

reduce energy costs in your building during company holidays, for example, you

could create a holiday calendar. On these days, your calendar might command the

system to reduce the output of heating or cooling systems when the building is

unoccupied.
