[Equest-users] loop flow

[B. Fountain]

Try setting your loop sizing to primary rather than secondary.  Primary
sizes the loop based on the chiller capacity -- good if your primary
equipment sizing is known.  Secondary sizes the loop based on the coils
attached to the loop -- good if you are autosizing your equipment.  The
default is secondary.
