Comments about Venstar Venstar Slimline Programmable MultiStage Thermostat - T1900:
I love this thermostat, which I've paired with the Telephone Interface System to control the temperature of a vacation cabin at 5000 ft near Tahoe. While the unit is very flexible (I just added a whole-house humidifier, which this thermostat controls), there's a lot of things you can program. I suspect many users will not get to adjust, or set, maybe 25-50% of them. But it's still an easy unit to install and program (at least in my experience).
