Hi all,

I'm working on a energy model for a data center in Seattle. The data
center is served by 10 packaged rooftop units. The adjacent Transformer
rooms, UPS room and RO room are conditioned by transfer air from the
data center. I actually divide the data center, the transformer room and
RO room into 10 average pieces so each roof packaged serves (4) areas
and these areas are not connected together. So in DD Wizard mode under
Zone Pattern (page 2 of 25), I outline (4) different spaces (not
connected together) as a group. The program then assigned one system for
each area even though I have assigned one system for each Zone Group in
page 14 of 25. How could that be ?

Thanks,
