APPENDIX B — CCN TABLES

All Z series units with ComtfortLink™ controls have a port

for interface with the Carrier Comfort Network

®

(CCN) sys-

tem. On TB3 there is a J11 jack which can be used for tempo-

rary connection to the CCN network or to computers equipped

with CCN software like the Service Tool. Also on TB3 there

are screw connections that can be used for more permanent

CCN connections.

In the following tables the structure of the tables which are

used with the Service Tool as well as the names and data that are

included in each table are shown. There are several CCN vari-

ables that are not displayed through the scrolling marquee and

are used for more extensive diagnostics and system evaluations.
