Hello,

I want to poll the group to make sure I haven't missed a thread on the
subject.

Is the only way to model a system that separates the ventilation
requirements and the space load (Heatpump, VRF, Fan coil, etc) by
creating a dummy shell with zero loads and then passing the OA from this
dummy shell to the individual zones with "OA-FROM-SYSTEM"? My specific
system this time is a GSHP with a RTU for ventilation air that is fired
by a condensing boiler.

either.

Thanks for you help,
