Some questions about DOAS in Ironbug

I’m starting with the template DOAS, there is only one Fan, I think there must be 2 fans, one for supply one for exhaust, right? another question is which component should I use if I want to explode the OAStream and ExStream parameter in OASystem?

At a minimum you just need one fan, it can be supply or exhaust.

Can you elaborate a little bit more on what you are wanting to do?

I’m not sure, it is just a litte bit against what I know. I thought as DOAS with Heat Recovery there should be 2 at least. So I wanna know how put 2 fans, just adding another one to the merge component? How does it define which for outside air or exhaust?

Ah! Okay cool,
away from machine at the moment but here’s an example of mine, not saying its right or wrong but; there’s two fans and its draw-through supply and draw-through exhaust
