Try setting the pump kW itself to 0, or at least 0.0001 if 0 doesn't
work.

Subject: [Equest-users] Steam loop pumping energy
All,
I'm modeling a university campus building with heat provided by central
plant steam boilers, providing 15# steam. I've done this by eliminating
boilers in the model and attaching a steam meter to the hot water loop.
My problem is with pumping energy. Equest requires that a pump be
attached to the hot water loop, but the actual installation has gravity
return condensate. How do I zero out the pumping energy? I have set
pump head = 0, but this gives me pages of error reports. Any other
methods?
Thanks,
Steven
