Min Flow Rate below Min OA

Hello,

I am modeling a VAV system and I am entering either Min-OA/person or Min-OA/area for each zone. I ran an hourly report and noticed that when I specify a minimum flow ratio the system flow rate will drop below the minimum OA rate.

Has anyone had this issue and is there a way to get the flow to stay above the ventilation requirement?

Thanks in advance,
