<DIV>HI equester:</DIV>
<DIV> I am working on project in which fresh air is controled by CO2 concentration, in my model, every room has FCU, and all fresh air provied by DOAS controling a dummy room. so the fresh air volume of this system is sum of all room served by FCU. and to realize this control , in every system tab, i choose DCV return sensor, but i don't kown how to setup the fresh air system(DOAS), if i also choose DCV return sensor, i think the volume of air provided by system is unchanged, because people im dummy room is 0. i tried to input number of people in room tab and total heat for 0,but is unaccepted by software. so this method is not ok.</DIV>
<DIV> dose any people can guide me? note that:my fresh air volume of DOAS must reflect requirement of all room served by FCU.</DIV>
<DIV> any words will be apreciated! </DIV>
<DIV>BEST REGARDS! </DIV><br><br><span title="neteasefooter"><span id="netease_mail_footer"></span></span>
