If the current occupancy period is unoccupied when the
occupancy override is initiated, the mode will change to
occupied for the duration of the number of hours downloaded.
If the occupancy override will end after the start of the next
occupancy period, the mode will transition from occupancy
override to occupied without becoming unoccupied, and the
occupancy override timer will be reset.
An active occupancy override or a pending occupancy
override may be canceled by downloading a zero to this
configuration. Once a number other than zero has been down-
loaded to this configuration any subsequent downloads of any
value other than zero will be ignored by the zone controller.

OCCUPANCY SCHEDULING — For flexibility of schedul-
ing, the occupancy programming is broken into eight separate
periods. For each period the scheduling, the active days of the
week, occupied start time, and occupied stop time needs to be
configured.
DAY OF WEEK — This configuration consists of eight fields
corresponding to the seven days of the week and a holiday
field in the following order: Monday, Tuesday, Wednesday,
Thursday, Friday, Saturday, Sunday, Holiday. A separate
configuration screen is used.
If a 1 is configured in the corresponding place for a certain
day of the week, the related “Occupied from” and “Occupied
to” times for that period will take effect on that day of the
week. If a 1 is placed in the holiday field the related times will
take effect on a day configured as a holiday. A zero means the
schedule period will not apply to that day.
Period (1-8):
Day of Week:
Range
0 or 1
Default Values
11111111 for period 1,
00000000 for periods 2-8.
OCCUPIED FROM — This field is used to configure the
hour and minute, in military time, when the mode for the zone
controller becomes occupied.
Period (1-8):
Occupied from:
Units
Hours: Minutes
Range
00:00 to 24:00
Default Value
00:00
OCCUPIED TO — This field is used to configure the hour
and minute, in military time, when the occupied mode for the
zone controller becomes unoccupied.
Period (1-8):
Occupied from:
Units
Hours: Minutes
Range
00:00 to 24:00
Default Value
24:00
Option Service Configuration Table —
The Op-
tion Service Configuration Table (OPTIONS) contains
decisions used to configure the service options of the zone
controller. This includes such things as whether the zone
controller is a global schedule master, a global set point master,
a broadcast acknowledger, and whether it will be using demand
control ventilation. This is also where loadshed parameters are
configured. See Table 12.
OCCUPANCY SCHEDULE NUMBER — The Occupancy
Schedule Number defines what Occupancy schedule the zone
controller will use. Occupancy Schedule 64 is a local schedule.
Occupancy Schedules 65 to 99 are global schedules.
Occupancy Schedule
Number:
Range
64 to 99
Default Value
64
GLOBAL SCHEDULE MASTER — The Global Schedule
Master configuration allows the Occupancy Schedule to be used
as a Global Schedule Master (Occupancy Schedules 65-99).
Global Schedule
Master:
Range
No/Yes
Default Value
No
OVERRIDE — The Override parameter is used to configure
the number of hours and minutes the override will be in effect.
The user initiates override by pressing the override button on
the space temperature sensor. This will cause the schedule to
enter into the Occupied mode. If global scheduling is used, all
zones using the global schedule will enter Occupied mode.
Pushing the override button during Occupied mode will have
no effect.
If the occupancy override is due to end after the start of the
next occupancy period, the mode will transition from occupan-
cy override to occupied without becoming unoccupied, and the
occupancy override timer will be reset.
NOTE: If using the tenant billing function, the override
hours set point must be configured between 1 and 3 hours.
Override:
Units
Hours: Minutes
Range
00:00 to 24:00
Default Value
00:00
SET POINT GROUP NUMBER — The Set Point Group
Number is used to define the current zone controller as a part of
a group of zone controllers which share the same set points. All
zone controllers with the same Set Point Group Number will
have the same set points. The set points are broadcast to the
group by the zone controller defined by the Global Set Point
Master configuration. A value of 0 is a local schedule. Values 1
to 16 are used for global scheduling.
Set Point
Group Number:
Range
0 to 16
Default Value
0
GLOBAL SET POINT MASTER — This configuration de-
fines if the current zone controller will broadcast its set point
values to the other zone controllers which are made part of the
same group by configuring the Set Point Group Number.
Global Set Point
Master:
Range
No/Yes
Default Value
No
MAXIMUM OFFSET ADJUSTMENT — This configuration
determines the maximum amount that the set point will be bi-
ased (up or down), by adjusting the slide bar on the space tem-
perature sensor (if installed).
Maximum Offset
Adjustment:
Units
delta F (delta C)
Range
0 to 15
Default Value
2
BROADCAST ACKNOWLEDGER — This configuration
defines if the zone controller will be used to acknowledge
broadcast messages on the communication bus. One broadcast
acknowledger is required per bus, including secondary busses
created by the use of a bridge.
Broadcast
Acknowledger:
Range
No/Yes
Default Value
No
LOADSHED FUNCTION GROUP NUMBER — This de-
cision is used to assign the number that the loadshed function
will use when transmitting alerts and commands to differenti-
ate this loadshed group from any other loadshed group in the
network. The loadshed algorithm is disabled if the value
0
is
entered in this decision.
Loadshed Function
Group Number:
Range
0 to 16
Default Value
0
