Table 16 — Linkage Maintenance Table
REF ZONE TEMPERATURE — This variable displays the
weighted average of the space temperatures, collected by the
linkage coordinator, from polling its associated zones. The
temperatures are weighted by the maximum airflow capacities
of the zone controllers scanned by the linkage coordinator.

OCCUPIED REF ZONE TEMPERATURE — This variable
displays the weighted average of the space temperatures of
occupied zones, collected by the linkage coordinator, from
polling its associated zones. The temperatures are weighted by
the maximum airflow capacities of the zone controllers
scanned by the linkage coordinator.

COMPOSITE CCN VALUE — This variable displays the
high, low or average of the CCN variable collected from each
zone as configured in the Linkage Master (Coordinator) Con-
figuration Screen. The value is sent to the network address and
variable specified within that configuration table.

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.

NEXT OCCUPIED DAY — This variable displays the day
when the next associated zone is scheduled to change from
unoccupied 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 TIME — This variable displays the time
of day when the next associated zone is scheduled to change
from unoccupied to occupied mode. This point is read in con-
junction with the next occupied day to allow the user to know
the next time and day when a zone will become occupied.

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 TIME — This variable displays the
time of day when the next associated zone is scheduled to change

PREVIOUS UNOCCUPIED DAY — This variable displays
the day when the last associated zone changed from occupied
to unoccupied mode. This point is read in conjunction with the
previous unoccupied time to allow the user to know the last
time and day when a zone became unoccupied.
