Airzone ZBS Zoning System
I came across the Airzone ZBS system the other day. This looks to be a fairly sophisticated ducted zoning system that is capable of integrating with Mitsubishi air handlers as well as controlling up to two stages of auxiliary heat. At a glance, it looks like Airzone may be the OEM for the controls used for the Daikin DZK system as well.
Does anyone here at GBA have any experience with this system? I’m interested in it for the ducted portion of my Mitsubishi system. Given that it’s listed on the Mitsubishi site, this looks to be something that is sanctioned by Mitsubishi as well, so no warranty issues to worry about down the road.
The documentation shows that the system supports full proportional control of the zone dampers (not just on/off) and is capable of controlling the fan speed of the air handler based on a weighted demand from each zone.
I haven’t yet located any dealers for Airzone in the US. I’m sure it’s an expensive system, but there aren’t any other off-the-shelf solutions that I’m aware of.

I'm not sure about the US, but in Ontario, Canada you could call Rob at Mits Air. I believe they have some experience with the system.
Worth looking into. It's easy to show that a system with fixed ratios of heat/cooling will typically have some uncomfortable room-to-room variations in temperature.
