APPENDIX B — CCN TABLES
All Z series units with
Comtfort
Link™ 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.
