perhaps the question is "are you referring to a zone or a zone group?"
in the ddwizard you can specify multiple zones into a zone group. so if
every space, i.e. every room, is it's own zone, then you could add
multiple spaces to a zone group. otherwise you're just making a thermal
zone composed of multiple spaces. as far as i know.
