Just wanted to share an e-mail from Jeff. I did not know that an ERV on a
OA-From system was not supported by eQuest. That explains why I could never get
the correct airflows on this type of design.

Unfortunately almost every project I work on does specify a VAV DOAS with an ERV
to supply ventilation air to some type of HVAC system, such as VRF indoor coils,
chilled beams or PTHP units. I will have to try the work around Jeff suggested.
