If no mode is currently active, the Linkage Coordinator will

determine the mode by first comparing the AHD and the ACD.
If only one demand is greater than the start demand (Heat Start
Avg. Demand or Cool Start Avg. Demand in the Master [Link-
age Coordinator] Service Configuration table), the system will
start in that mode. If both average demands are greater than the
configured minimum average demand required to begin a
mode, then the mode with the greatest demand will be selected.
If both heating and cooling average demand are exactly the
same then the mode with the greatest individual zone demand
will determine the system mode.

Once the mode is selected, the information is communicat-

ed to its air source via the Linkage Coordinator so that the air
source may respond to the requested mode. The Linkage Coor-
dinator also has the capability of locking out the mode based on
the outside air temperature (OAT). If the OAT has exceeded the
lockout set point for that mode, then the Linkage Coordinator
will not request that mode from the air source. There is a fixed
3° F hysteresis on the heating and cooling set points before a
mode is re-enabled.

Once a mode has begun, the system mode reselect timer is

started to monitor the elapsed time of the operating mode. A
mode will end when the average demand for that mode drops
below the average demand hysteresis for the mode (Heat Mode
Hysteresis or Cool Mode Hysteresis in the Master [Linkage
Coordinator] Service Configuration table). If a system mode is
currently active and the average demand for the opposite mode
becomes greater than the current mode average demand, and
the opposite mode demand is also greater than the mode Start
Avg. Demand for that mode, then the system mode may
change but only after the system mode reselect time of the cur-
rent mode exceeds the configured System Mode Reselect timer
value. If these are all true, the system will begin the change to
the opposite system mode. This is accomplished by sending in-
formation to the air source that ends the current mode. The
Linkage Coordinator then waits for the supply-air temperature
(SAT) to fall within the ventilation temperature range of 65 to
75 F. Once that occurs, the opposite mode is started.

If the mode is dropped due to the reselection criteria

above, the algorithm will not permit the original mode to be
re-established unless there is sufficient average demand to start
the new mode. This is true even if the old mode has once again
become the more dominant requirement.

Linkage —

Linkage is the process used to communicate

between the air source (HVAC equipment) and the zone termi-
nals to form a coordinated HVAC system. Linkage allows the

air source to be controlled by the demands of the zones and
allows the zones to properly respond to the changes in the air
source operating modes. Linkage operation in air sources that
have Carrier communicating network controls such as
48/50HG, 48/50A, and 48/50Z Product Integrated Controls
(PIC) series rooftop units, PremierLink™ control or Universal
Controller is supported. Existing air sources that do not have
Carrier communicating network controls may be retrofitted
with PremierLink or a Universal Controller depending on the
equipment type. The designated Linkage Coordinator of each
system will be the Linkage Coordinator between the air source
and its associated zones.
AIR SOURCES THAT SUPPORT LINKAGE — Air sourc-
es with PICs or PremierLink controls do not require any
configuration settings to establish linkage with the Linkage
Coordinator. This is done automatically when the air source
bus and element address are configured in the Linkage Coordi-
nator’s LINKAGE configuration table. The linkage informa-
tion that is supplied to the air source by the Linkage Coordina-
tor is as follows:
• Reference zone temperature
• Reference zone occupied biased heating and cooling

setpoints

• Average unoccupied heating and cooling set points of all

zones serviced by the air source

• Composite occupancy mode

The air source will control the equipment based on this

information and in return will provide the Linkage Coordinator
with the following data:
• Operating mode — Cooling, Heating, Free Cool, Pres-

sure, Evacuation or Off

• Supply-air temperature

This synchronization of data optimizes the efficiency of the

air source and the zones to operate at peak system performance
at all times. This information can be seen in linkage mainte-
nance tables of the Linkage Coordinator and the air source and
is updated at approximately 1-minute intervals.

The reference zone temperature that is sent by the Linkage

Coordinator will vary depending on the current demand. At
times this will be a calculated value instead of an actual value
to allow the air source to turn off heating or cooling after the
current mode is satisfied or as it makes a transition to a mode.
Table 24 defines when these values will be sent and how they
are determined.
