A couple of years ago I replaced my old home heating thermostat with an electronic one from Home Depot. It ran on a couple of AA batteries, had several programmable on/off cycles for the furnace and worked pretty good for a while till the touch screen quit. Got a replacement under warranty, slightly different model that required an entirely different mounting. The new one works fine, also powered by AA batteries.
Anyone considering these needs to know that there's no backup for the batteries. When they die the house gets cold. The new thermostat eats (cheap) batteries in about a month. The original thermostat, with a mercury contact, lasted forever and wasn't battery powered. When I get time I'll run more wires between the thermostat and the furnace to bring power to the thermostat in addition to the batteries, which is a nice feature of this thermostat.
The thread on testing batteries reminded me I wanted to post this before the heating season begins.
