<p class=MsoNormal>Hello folks,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hopefully someone knows how to deal with outside air. I
can’t seem to figure out how to set my minimum outside air on my HVAC
systems. When I set my OA minimum on my Air system , and adjust the
minimum OA fraction in my schedule I still get ventilation results below my set
minimum. It seems, no matter what I do to the outside air setting on the
system side the program sizes the OA ventilation based solely on what my
outside air ventilation rates of the individual spaces and ignores any setting
I put in my system. Does anyone have experience on how to remedy this?<o:p></o:p></p>
