trying to model the 3 pumps in 3 separate loops is because we’re thinking
of dropping one of the pumps out and re-plumbing due to changes in zoning
within the building. So I’m trying to set up a good base model for
this.</span></font></p>

style='font-size:11.0pt;font-family:Arial;color:navy'>Hello – this is an
elementary question, but I wasn’t able to find an answer in the archives
or in the DOE help screens. (Or I’m not finding the answer I
want...)</span></font></p>

<p class=MsoNormal style='margin-left:.5in'><font size=2 color=navy face=Arial><span
style='font-size:11.0pt;font-family:Arial;color:navy'>I’m using Equest
and have a system with 2 hot water boilers that are staged. The system
has 3 pumps serving 3 separate zones. What I am trying to do is set up 3
separate hot water loops connected to the 2 boilers. However, it appears
that I can’t have more than one loop per boiler. The boilers are
not set up with a primary/secondary loop (with the boilers having their own
pumps); if I do set up the plant with a primary/secondary loop can I then
attach multiple secondary hot water loops to the primary loop? If so how do I
do this? Or am I missing something really basic here – it seems
like almost every boiler plant I’ve ever seen has multiple staged boilers
and multiple zones with multiple pumps. It’s so common it seems
like it must be (easily) model-able.</span></font></p>
