It's coming to Canada, so I may just pick one sooner or later. Mostly because it looks cool though.
Even with a flexible scheduling thermostat I tend to keep it set to a constant temp, only making a small adjustment if I have a special requirement.
I also tend to keep it the same temp while I'm home, but I'd like to start having the system turn off while I'm not around.
I've always wondered, what's the threshold for energy savings? I have to imagine that reheating a place in the winter after you've been out must take more energy than maintaining a constant temp. So I wonder how long you'd have to be out in order to make it worthwhile. Sorry if I wasn't clear...
