Products Covered
This System Engineering Guide describes how to apply the
Excel 10 FCU Controllers and the accessories to typical FCU
applications. The specific devices covered include:
• W7752D,E,F,G, and J FCU Controllers.
• W7754K,L,M,N, and P FCU Controllers.
• T7460 Wall Modules.
• T7560 Wall Modules.
Organization of Manual
The Introduction and Application Steps 1 through 5 provide
the information needed to make accurate ordering decisions.
Application Step 6 and the Appendices include configuration
engineering that can be started using a LNS tool after the
devices and accessories are ordered. Application Step 7 is
troubleshooting. Information provided in support of the use of
third-party LonWorks communication packages to configure
FCU Controllers is found in the Appendices.
The organization of the manual assumes a project is being
engineered from start to finish. If you are adding to, or
changing an existing system, the Table of Contents can guide
you to the relevant information.
