[Equest-users] Chillers in Series inputs

[Rob Hudson]

I won't claim that this is correct whatsoever, but briefly looking at your
set up, it is clear that the water isn't pulling extra load from the second
chiller.  I think you may want to set up a single chiller because I don't
see a way to get the water to go through both chillers.  You could also
create your own custom curves so that you match the combined performance of
the modeled chiller.

Just a thought.
