APPENDIX B — CCN TABLES
All A series units with ComtfortLink™ controls have a port
for interface with the Carrier Comfort Network (CCN). On
TB3 there is a J11 jack which can be used for temporary con-
nection 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. As a reference the equiv-
alent Scrolling Marquee tables and names are included. There
are several CCN variables that are not displayed through the
Scrolling Marquee and are used for more extensive diagnostics
and system evaluations.
