Optimal Start/Stop
Optimal start and stop times can be defined for HVAC schedules. HVAC refers to both Area and
equipment.
The schedule coordinates with the Area application or equipment to calculate when the optimal
start and stop occurs. Optimal start/stop times are based on outside air conditions, space
temperature, and occupied setpoints.
Exceptions and Calendars
Exceptions are temporary modifications to a schedule. Exceptionscontain one set of dates or one
repeating pattern of dates. If a schedule has an exception applied, a red box outline will appear.
Calendars
For multiple dates and repeating patterns a calendar can be created, which is then applied to the
exception.
Calendars are used to group dates, which can then have exceptions applied to these dates on a
schedule. For example, a school might create a calendar to group the days that require extended
operating hours for after-school meetings.
Release Function
The release function is a predetermined time in which the present schedule or the event releases
control over to the next event based on priority. Conceptually, a scheduled release is very similar
to a timed override. For example, after the daily schedule ends at 12:00 am (midnight), the schedule
releases control over to the next event.
Creating a Schedule
The system controller leads you through the process of creating a schedule for your facility by
navigating through a series of steps and pages, often referred to as a "wizard." If you need help
completing the steps, click the help icon located on each page. You can create a schedule to control
the following points and applications based on time and date:
• Binary outputs and values
• Analog outputs and values
• Multistate outputs and values
• Equipment, spaces, and system applications (typically referred to as HVAC schedules)
Points and applications are referred to as members when they are assigned to a schedule.
Members can be assigned to only one schedule during the same effective period. Members must
be the correct type; that is, a binary point cannot be included in an analog schedule.
To create a schedule:
1. Click the create schedule button. The Create Schedule—Schedule Information page
appears.
2. Enter a name for the schedule, and select the schedule type and effective dates.
3. Click next to continue. The Create Schedule—Select Members page appears.
4. From the selection tree , select members (spaces and areas) for the schedule, then click Add
to move to selected items .
5. Click next to continue. The Create Schedule – Schedule Times page appears.
6. Select a schedule default. Each day is independent of the others and always begins with the
schedule default value. The schedule default value is applied to each day of the week and is
the value that the schedule defaults to at 12:00 a.m. for any given day. Select Release (see
below), Occupied, or Unoccupied.
