Composite CCN Value

— This variable displays the high, low

or average of the CCN variable collected from each zone as

configured in the Linkage Coordinator Configuration Screen.

The value is sent to the CCN address and variable specified

within that configuration table.

Composite

CCN Value: Display Range 0-65535

Default Value 0

Network Access Read Only

Occupancy Status

— This variable displays a “1” when at

least one of the associated zone controllers (that are being

scanned) is in the occupied mode.

Occupancy Status:Display Range 0 or 1 (1 = occupied)

Default Value 0

Network Access Read only

Next Occupied Day

— This variable displays the day when

the next associated zone is scheduled to change from unoccu-

pied to occupied mode. This point is read in conjunction with

the next occupied time to allow the user to know the next time

and day when a zone will become occupied.

Next Occupied

Day: Display Range MON, TUE, WED,

THU, FRI, SAT, SUN

Default Value No display (Blank)

Network Access None

Next Occupied Time

— This variable displays the time of day

when the next associated zone is scheduled to change from un-

occupied to occupied mode. This point is read in conjunction

with the next occupied day to allow the user to know the next

time and day when a zone will become occupied.

Next Occupied

Time: Display Range 00:00 to 24:00

Default Value 0:00

Network Access None

Next Unoccupied Day

— This variable displays the day when

the next associated zone is scheduled to change from occupied

to unoccupied mode. This point is read in conjunction with the

next unoccupied time to allow the user to know the next time

and day when a zone will become unoccupied.

Next Unoccupied

Day: Display Range MON, TUE, WED,

THU, FRI, SAT, SUN

Default Value No display (Blank)

Network Access None

Next Unoccupied Time

— This variable displays the time of

day when the next associated zone is scheduled to change from

occupied to unoccupied mode. This point is read in conjunction

with the next unoccupied day to allow the user to know the

next time and day when a zone will become unoccupied.

Next Unoccupied

Time: Display Range 00:00 to 24:00

Default Value 0:00

Network Access None

Previous Unoccupied Day

— This variable displays the day

when the last associated zone changed from occupied to unoc-

cupied mode. This point is read in conjunction with the previ-

ous unoccupied time to allow the user to know the last time and

day when a zone became unoccupied.

Previous Unoccupied

Day: Display Range MON, TUE, WED,

THU, FRI, SAT, SUN

Default Value No display (Blank)

Network Access None

Previous Unoccupied Time

— This variable displays the time

of day when the last associated zone changed from occupied to

unoccupied mode. This point is read in conjunction with the

previous unoccupied day to allow the user to know the last time

and day when a zone became unoccupied.

Previous Unoccupied

Time: Display Range 00:00 to 24:00

Default Value 0:00

Network Access None

Maximum Damper Position

— This variable displays the

damper position of the zone controller in the system with the

damper in the most open position. This is used by the linkage

coordinator to calculate the static pressure reset.

Maximum Damper

Position: Display Units % (open)

Display Range 0.0 to 100.0

Default Value 0.0

Network Access Read/Write

Static Pressure Reset

— This variable displays the current

static pressure reset calculated, using the maximum damper po-

sition and the configuration information from the linkage con-

figuration table.

Static Pressure

Reset: Display Units in. wg

Display Range 0.0 to 5.0

Default Value 0.0

Network Access Read/Write

Pressure Decrease Value

— If the maximum damper position

in the system goes below the minimum configuration setting,

the linkage coordinator will calculate an amount that the static

pressure should be decreased. This is used to open the system

dampers more so that they will modulate between their mini-

mum and maximum settings.

This number is rounded to the nearest tenth of an inch and

will be added to the static pressure reset value unless the static

pressure reset value has reached maximum reset.

Pressure Decrease

Value: Display Units in. wg

Display Range 0.000 to 5.000

Default Value 0.000

Network Access Read/Write

Pressure Increase Value

— If the maximum damper position

in the system goes above the maximum configuration setting,

the linkage coordinator will calculate an amount that the static

pressure should be increased. This is used to close the system

dampers more so that they will modulate between their mini-

mum and maximum settings.

This number is rounded to the nearest tenth of an inch and

will be subtracted to the static pressure reset value unless the

static pressure reset value has reached zero.

Pressure Increase

Value: Display Units in. wg

Display Range 0.000 to 5.000

Default Value 0.000

Network Access Read/Write

OCCUPANCY MAINTENANCE TABLE — The Occu-

pancy Maintenance table is used to view the occupancy set

points. See Table 14.

Mode

— This variable displays the current occupied mode for

the zone controller. If the zone controller is following its own

local schedule, this is the result of the local schedule status. If

the zone controller is configured to follow a global schedule,

this point displays the mode last received from a global sched-

ule broadcast.

Mode: Display Range 0 or 1 (1 = occupied)

Default Value 0

Network Access None
