Can you use PVVT, but configured as you would have setup the heat pump?

Hello All!

I am having an issue regarding a dedicated outside air unit that takes
advantage of a condensing water loop.

When modeled as a water source heat pump (TYPE = HP), eQUEST gives me an
error saying this system type is not eligible for ?OA-FROM-SYSTEM?.

One of my thoughts is to

? model all the units served by the outside air unit with no fresh
air

? model the dummy zone with a summation of the fresh air required
by the spaces served

But then that might interfere with a proper simulation of mixed air temps
going into the space.

Thoughts?
