Connect to CCN Communication Bus —
The
PremierLink™ controller connects to the bus in a daisy chain
arrangement. Negative pins on each component must be
connected to respective negative pins (and likewise positive
pins on each component must be connected to respective posi-
tive pins). The controller signal pins must be wired to the signal
ground pins. Wiring connections for CCN must be made at the
3-pin plug.
At any baud (9600, 19200, 38400), the number of control-
lers is limited to 239 devices maximum. Bus length may not
exceed 4000 ft, with no more than 60 total devices on any
1000-ft section. Optically isolated RS-485 repeaters are
required every 1000 ft.
NOTE: Carrier device default is 9600 baud.
COMMUNICATION BUS WIRE SPECIFICATIONS —
The CCN Communication Bus wiring is field-supplied and
field-installed. It consists of shielded three-conductor cable
with drain (ground) wire. The cable selected must be identical
to the CCN Communication Bus wire used for the entire net-
work. See Table 4 for recommended cable.
Table 4 — Recommended Cables
NOTE: Conductors and drain wire must be at least 20 AWG,
stranded, and tinned copper. Individual conductors must be
insulated with PVC, PVC/nylon, vinyl, Teflon, or polyethyl-
ene. An aluminum/polyester 100% foil shield and an outer
jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a
minimum operating temperature range of –20 C to 60 C is
required.
The communication bus shields must be tied together at
each system element. If the communication bus is entirely
within one building, the resulting continuous shield must be
connected to ground at only one single point. If the communi-
cation bus cable exits from one building and enters another
building, the shields must be connected to the grounds at a
lightning suppressor in each building (one point only).
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, or Network Service Tool.
The Network Service Tool is a portable interface device that
allows the user to change system set-up and set points from a
zone sensor or terminal control module. During start-up, the
Carrier software can also be used to verify communication
with PremierLink 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 the 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.
Install Navigator —
The Navigator is a portable dis-
play module that conforms to NEMA 4 specifications for
outdoor use in temperatures ranging from –22 F (–30 C) to
158 F (70 C). The Navigator can be used to configure and
perform service diagnostics on machines equipped with the
PremierLink Controller. See Fig. 7.
The Navigator keypad contains eleven menu LEDs and one
Alarm Status LED, all of which are red. The Navigator is capa-
ble of displaying four 24-character lines of information on a
backlit liquid crystal display. The Navigator has four functional
keys which are the up arrow ( ), down arrow ( ),
and keys.
INSTALLATION — The Navigator display module is intend-
ed to be a mobile device, so there are no holes in the device for
permanent mounting. The module has a magnetic mount that is
strong enough to hold the device in place on any clean, dry
metal surface.
