What you may want to think about doing is putting multiple styles on your display T4. I would show a simpler design, with text completely done in ID. Then I would show a second, more elaborate design (like the one you described in your post) for the people who like to have all the options for thier equipment.

It would require you to double up the total page count but your home page could be the point where the GUI branches in two completely different directions. I have a Modero 8.4 that I take to client meetings that pretty much has what I described.

Complete blueprints for room / zone select versus a page with simple text buttons arranged in columns grouped by floor etc..

You definitely want to limit it to three different choices.
