I just came up with this same problem now. I am using two different VRF systens, that are:
Those two systems are independent and assigned for all Thermal Zones that have people and so need OA.
In this case, setting up the 1) VRF System only for Cooling/Heating with "Outdoor Air Flow Rate When No Cooling or Heating is Needed” to “0” and also setting the 2) VRF System only for OA with "Supply Air Fan Operating Mode Schedule" of "0" will represent the need of both systems to be on when there are people in Thermal Zone and Cycle when there is no one in the Thermal Zone (which is what LEED requires).
Is that understanding right?
Sorry for comming up with this old question again.
Thanks in advance for all your help.
@Erik Kolderup @Lyle K and anyone that could help.
