Table 13 — Linkage Maintenance Screen
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.
