I don't know about the 4kq systems, but the manual for my 100 and 200 says
the "bi-level" setting on the Climate Control panel will direct heated air
through the center vents as well as to the floor. It seems to affect things
in that sense, but even so, I've haven't yet gotten what I'd call a really
satisfying blast of warm air from the center vents even with "bi-level"
mode. Maybe "bi-level" is only intended to mix in a smidgeon of warm air
for those vents.
