I find it easiest to use HVACTemplate to build the initial system, then expand the IDF and customize. That way the expansion macro will add all the connections you need (except those components that are not supported by the Template objects). We wrote a Python script to map the expanded system node for node so we can see where to modify connections and controllers. Before that, we almost always had to map the system diagram by hand to keep track of all the connctions and add new ones without typos. The SVG file is useless in this regard.

Subject: [EnergyPlus_Support] Energy Plus - adding multiple fancoils to zone in the idf

I've just started going through the excersize of adding additional fancoils to a zone.

Each FC has to be defined.

Each additional FC has to lie on it's own branch split from the plantloop demand side splitter (as only one splitter per loop is allowed).

The same for the demand side mixer.

And the Demand side branch list has to be updated with the extra branches.

AND THAT'S JUST FOR HOT WATER...the same still goes for CW.
------------------------
Even though all the fancoils may be the same!

Is their no way to use a multiplier of sorts to only have to do this once? Or at least once per Fancoil type?

I just had a project with hundreds of zones, each with up to 20 fancoils consisting of variants of 4 different types.
