START-UP

Use the Carrier network communication software to start up

and configure the PremierLink controller.

Changes can be made using the ComfortWORKS

soft-

ware, ComfortVIEW™ software, Network Service Tool, Sys-

tem Pilot™ device, or Touch Pilot™ device. The System Pilot

and Touch Pilot are portable interface devices that allow the

user to change system set-up and set points from a zone sensor

or terminal control module. During start-up, the Carrier soft-

ware can also be used to verify communication with Premier-

Link controller.

NOTE: All set-up and set point configurations are factory-

set and field-adjustable.

For specific operating instructions, refer to the literature

provided with user interface software.

Perform System Check-Out

1. Check correctness and tightness of all power and

communication connections.

2. At the unit, check fan and system controls for proper

operation.

3. At the unit, check electrical system and connections of

any optional electric reheat coil.

4. Check to be sure the area around the unit is clear of

construction dirt and debris.

5. Check that final filters are installed in the unit. Dust and

debris can adversely affect system operation.

6. Verify that the PremierLink controls are properly

connected to the CCN bus.

Initial Operation and Test — Perform the following

procedure:

1. Apply 24 vac power to the control.

2. Connect the service tool to the phone jack service port of

the controller.

3. Using the Service Tool, upload the controller from

address 0, 31 at 9600 baud rate. The address may be set at

this time. Make sure that Service Tool is connected to

only one unit when changing the address.

MEMORY RESET — DIP switch 4 causes an E-squared

memory reset to factory defaults after the switch has been

moved from position 0 to position 1 and the power has been

restored. To enable the feature again, the switch must be put

back to the 0 position and power must be restored; this pre-

vents subsequent resets to factory defaults if the switch is left

at position 1.

To cause a reset of the non-volatile memory (to factory

defaults), turn the controller power off if it is on, move the

switch from position 1 to position 0, and then apply power to

the controller for a minimum of 5 seconds. At this point, no

action occurs, but the controller is now ready for the memory

to reset. Remove power to the controller again and move the

switch from position 0 to position 1. This time, when power is

applied, the memory will reset to factory defaults. The control-

ler address will return to bus 0 element 31, indicating that

memory reset occurred.

Sequence of Operation

THERMOSTAT MODE — If the PremierLink™ controller is

configured for Thermostat mode (TSTAT), it will control only

to the thermostat inputs on J4. These inputs can be overridden

through CCN communication via the CV_TSTAT points dis-

play table. When in this mode, the fire safety shutdown (FSD)

NOTES:

1. Switch on actuator must be in run position for economizer to operate.

2. PremierLink™ control requires that the standard 50HJ540569 outside-air sensor be replaced by either the CROASENR001A00 dry bulb sen

sor or HH57A077 enthalpy sensor.

3. 50HJ540573 actuator consists of the 50HJ540567 actuator and a harness with 500-ohm resistor.

The unit must be electrically grounded in accordance with

local codes and NEC ANSI/NFPA 70 (American National

Standards Institute/National Fire Protection Association).
