Was your original question about the availability of square dampers? If
so, yes they are out there, I can give you links if you decide to pursue
it again.
I haven't done anything yet, but I have traced enough of my ducts to
know that I can get three zones pretty easily. Basement as a zone,
ground and upper floors as a zone, and a sunroom-style addition as a
zone. It's the latter that is the most troublesome, as it loses so much
heat it's pretty much unusable in the winter unless I leave the door
open and the furnace fan on.
So if I limit myself to the above, I can put all the dampers in the
furnace room right where they all diverge, simplest installation.
If I could though, I would like to separate the ground floor from the
upstairs, but that might be hard to do based on where I think the ducts
go. That might require putting the dampers at the exits of the ducts,
and fishing the wires back down the ducts to the controllers. Maybe not
as a first step.
That's about where I sit. I am just about to order the kit, but I might
not get all the dampers right away. I might just run it as a very
expensive digital thermostat with three screens, but it would be an
upgrade from the mechanical one this house came with until I get my
stuff together.
I would also like to replace my fan motor with a variable speed one,
which the Envirazone can apparently control.
Does anybody know how these work? The envirazone surely only has low
voltage control, can I get a generic variable speed motor, bolt it where
mine is, and somehow wire that up?
