About this file
This document is installation instructions for the Carrier Comfort System PremierLink Accessory Remote Communications Board (Part Number 33CSREMCCN).
The remote communications board is an accessory component designed to enable CCN (Carrier Comfort Network) or LEN (Local Equipment Network) communications with the PremierLink controller. The package includes the communications board, two mounting brackets, two short machine screws, and two self-drilling mounting screws. Installation requires a battery-operated drill with Phillips head bit, Phillips head screwdriver, wire strippers, and mechanical wire fasteners. The board should be mounted inside an available service access panel in the low voltage termination box in a dry location with 3 to 4 inches of clearance for service access and wiring. The board features two RJ14 connectors: the left connector supports LEN connections and can power a Navigator display module, while the right connector handles CCN communication. The left connector's red, white, and black wires connect to the J2 communications connector on the PremierLink controller, and red and brown wires connect to 24 VAC from the unit transformer. The right RJ-14 jack connects to the CCN bus via screw terminals, with red, white, and black wires also connecting to the J2 connector. Users must refer to the PremierLink installation instructions for DIP switch settings to configure LEN or CCN communications.

Installation Instructions Part Number 33CSREMCCN
GENERAL
The accessory CCN remote communications board is used when CCN (Carrier Comfort Network) or LEN (Local Equip-ment Network) communications are needed with the Premier- Link controller. The remote communications board is wired to the PremierLink controller and provides two RJ14 connectors for CNN and LEN communication and 4 screw connectors for field connection to the CCN bus.
PACKAGE CONTENTS
• remote communications board
• 2 brackets
• 2 short machine screws
• 2 self-drilling mounting screws
TOOLS REQUIRED
• Battery-operated drill with Phillips head bit
• Phillips head screwdriver
• Wire strippers
• Mechanical wire fasteners
INSTALLATION
Location — The remote communications board should be mounted inside one of the available service access panels in the low voltage termination box. The location should be dry and allow sufficient access for wiring and service. Make sure the installation location will not leave any sharp points from the installation screws exposed.
For service access, there should be at least 3 to 4-in. of clearance around the board and adjacent surfaces. The location should be close enough to the PremierLink controller to allow clear routing of the wires in the harness to the communications connector (J2). Make sure there are no high voltage wires or contactors near the board.
Mounting — Two brackets are used to mount the board to the access panel. Two short machine screws with dimpled washers are used to connect the remote communications board to the brackets. The brackets consist of two right angles fas-tened together with a machine screw.
Place the threaded hole at one end of the bracket under the communications board. Use one of the short machine screws with the dimpled washer to fasten the bracket to the communi-cations board. Repeat for the remaining bracket.
The mounting end of the bracket may be positioned away from the communications board (if space permits) or may be positioned under the communications board (if required by the mounting location). See Fig. 1. If the brackets can be posi-tioned outward, line the board up in the desired location and use the battery operated drill to secure the bracket to the mount-ing surface using the 2 self-drilling screws provided.
If the desired installation has the brackets positioned under the communications board, then locate the board in the mount-ing location. Mark the center of the holes in the mounting brackets under the communications board. Remove the brack-ets and secure them to the mounting surface using the hole markings made previously. Once the brackets are secured, fasten the communications board to the brackets.
Wiring — The remote communications board has two RJ14 connectors. See Fig. 1.
The left connector is used for LEN connections and can pro-vide power to a Navigator display module. The left set of red, white and black wires should be connected to the J2 communi-cations connector on the PremierLink controller for using the left jack to support a Navigator display module.
The red and brown wires should be connected to 24 VAC from the unit transformer that is powering the PremierLink controller. Make sure polarity is correct or the PremierLink controller may be damaged.
The right RJ-14 jack is used for CCN communication. Con-nect the screw terminals on the remote communications board to the CCN bus. Connect the right red, white, and black wires to the J2 connector on the PremierLink controller. Refer to the PremierLink installation instructions for setting the DIP switch for LEN or CCN communications.
