[EnergyPlus_Support] Outdoor Air Mixing Boxes

Hi Everyone,

Is it possible to include two OA mixing boxes in a single air loop?

I'm getting an error that I think may be caused by including two oa mixing boxes in a single loop. I began my system using the templates. I created a dedicated outdoor air system (that didn't serve any zones) so I could later combine it with another air loop. After expanding the idf and combining the air loops, I am getting an error:

 ** Severe  ** Output:PreprocessorMessage="ExpandObjects" has the following Fatal conditions:
   **   ~~~   ** You must specify at least one
   **   ~~~   ** HVACTemplate:Zone:FanCoil/PTAC/PTHP/WaterToAirHeatPump served by a
   **   ~~~   ** HVACTemplate:System:DedicatedOutdoorAir. Did not find of match for ERU
   ** Severe  ** Output:PreprocessorMessage="ExpandObjects" has the following Fatal conditions:

   **   ~~~   ** HVACTemplate:System:DedicatedOutdoorAir. Did not find of match for ERU

This doesn't make sense to me since I am not using templates anymore, and I essentially got rid of the ERU dedicated outdoor air unit.

Any help would be appreciated, especially the first question above.
