APPENDIX B — CCN TABLES
All P Series units with ComtfortLink controls have a port for inter-
face with the Carrier Comfort Network
®
(CCN) system. On TB3,
there is a J11 jack which can be used for temporary 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 that are used
with the Service Tool as well as the names and data that are in-
cluded in each table are shown. There are several CCN variables
that are not displayed through the scrolling marquee and are
used for more extensive diagnostics and system evaluations.
