Re: Thermostat suggestions for radiant + HVAC + multiple zones

["chi" <mrpinebox@xxxxxxxxx>]

The forced air HVAC contractor is not sophisticated. He doesn't know
what zones are, much less automation or radiant heating (I asked,
"What's the work needed to set up 2 zones using some dampeners?"  His
response, "What's a zone and what's a dampener?").

The radiant heating installers prefer a single stage at each location.
They are willing to install for 2 stage, but only if I insist. They
pointed out various web sites for thermostat manufacturers (aprilaire,
tekmar, and luxpro) and that was all I got.

I notice that Tekmar specializes in hydronic/radiant heating controls.
Anyone have any experience with their controls in radiant heating
applications? They claim a thermostat controlling a hybrid system
should support pulse width modulation.

Kurt: I didn't mean to sound overly negative about the HAI appearance.
Just not quite as clean looking to my eyes as, say, the RCS line.
