Once Linkage is active, the PremierLink controller’s own SPT, temperature setpoints, and occupancy are ignored and the controller will use the information provided by the remote linkage device. The following information will be received from the remote linked device and can be viewed in the maintenance display table:

S Supervisory Element S Supervisory Bus

S Supervisory Block

S Average Occupied Heat Setpoint

S Average Occupied Cool Setpoint

S Average Unoccupied Heat Setpoint

S Average Unoccupied Cool Setpoint S Average Zone Temp

S Average Occupied Zone Temp S Occupancy Status

In return, the PremierLink controller will provide its SAT and operating mode to the linked device.

It will convert its operating modes to Linkage modes. See Table 14.

The PremierLink controller will generate a Linkage Communication Failure alarm if a failure occurs for 5 consecutive minutes once a Linkage has previously been established. It will then revert back to its own SPT, setpoints and occupancy schedule for control. For this reason, Carrier strongly recommends that an SPT be installed in the space on open plenum systems or in the return air duct of ducted return air systems to provide continued backup operation. When Linkage communication is restored, the controller will generate a return to normal.

For more information on how the PremierLink controller is used in conjunction with the Carrier 3V control system, contact your CCN controls representative.

IMPORTANT: The PremierLink controller should not be used as a linked air source in a ComfortIDt VAV system. The ComfortID VAV system will NOT function correctly when applied with a PremierLink controller as the air source, resulting in poor comfort control and possible equipment malfunction.

NOTE: The PremierLink controller can be used as an air source in a 3V Pressure Independent (PI) System (a 3V Linkage Coordinator with ComfortID PI Zone Controllers), but it should not be used as an air source with ComfortID controllers unless a 3V zone controller is used as the Linkage Coordinator. Contact your Carrier CCN controls representative for assistance.

Demand Limit — If the demand limit option is enabled, the control will receive and accept Redline Alert and Loadshed commands from the CCN loadshed controller. When a redline alert is received, the control will set the maximum stage of capacity equal to the stage of capacity that the unit is operating at when the redline alert was initiated.

When loadshed command is received the control will reduce capacity as shown in Table 15.

The controller will have a maximum demand limit timer of 1 hour that prevents the unit from staying in load shed or redline alert longer than 1 hour in the event the controller loses communication with the network load shed module. Should the maximum demand limit timer expire prior to receiving the loadshed device command from CCN, the control will stop demand limit mode and return to normal operation.
