Let's discuss the best method to model dedicated outdoor air. For starters, this is usually done by creating a dummy zone, assigning a dummy system to that zone, and then setting up your other systems to have Outdoor air provided by that system (in the detailed view).

Can anyone offer insight on this? I would like to put a "once and for all" document together as this subject as it comes up on the users list at least once a month. Of course, when adding heat recovery, it gets more confusing so include that if you can.
