DDC systems

Is the Honeywell Excel DDC system Bacnet compliant? In terms of market share in the controls industry, is the Excel system popular?- and with who?

    Post some background info so that we can define what you truly want to know. DDC systems, even within a single manufacturer's line, can have several configurations or options that would take volumes to discuss.

    BTW - Honeywell is one of the big 3 manufacturers as to DDC systems, and they've been doing it a long time. The ability for the local branch (or contractor) to meet and serve your needs is more important than the system itself, all things being equal.

    Hang on--I'll try to get answers from one of the Honeywell commercial reps.

    Here's the answer I got for the Honeywell commercial rep in Denver: The Excel is Lon and some older systems are C bus. We can integrate BackNet, Modbus and Lon, et al, with our Tridium based WEBS. Yes Excel is popular, however more movement towards WEBS (Tridium) and our XL 10 line. Churches, schools, airports etc.
