Hi,

I am using a 4 pipe IU and I put the outdoor air ratio to 1. When I
check my results I can see that the sum of the outside airflow is equal
to the supply capacity. But what do these values in supply flow for the
separate zones mean (I marked them red, see below)? Is there a
possibility to fix the amount of supply flow ? So far I figured out how
to fix the amount of outdoor air but in my building I supply always 2700
cfm per floor ?
