If the RTUs are identical, or at least of similar efficiency, my preference would be to combine their capacities, airflows etc. and model them as one unit/system. It is possible, but time-consuming to add zones once you have made changes in DD Edit mode. Be
sure to Save-As the model to work from a new copy if you experiment with modifying the geometry/zones in DD Edit mode.<o:p></o:p></p>
