Morning:

I am trying to model a chilled beam system as induction units. The primary air
is supplied by an ERU. I set the outside air to 0 on the chilled beams HVAC
systems tab.

In the chilled beam zone tab I set the outside air to the primary CFM and the
overall CFM to the induced air flow.

Per the eQuest help menu, "The sum of the OA requirements for all SYSTEMs that
reference an OA-FROM-SYSTEM is used to set the referenced OA-FROM-SYSTEM value
for MIN-OUTSIDE-AIR, SUPPLY-FLOW as well as adjust the referenced
OA-FROM-SYSTEM directly served ZONE maximum and minimum flows for both heating
and cooling."

But per my hourly reports, the ERU is not supplying the necessary amount of
primary air and in the summer the ERU flow drops to .01 CFM.

Attached are the project files. Any ideas?

Thank you,
