Easy to install, simplistic to use. Just select the desired unit, heater or aircon, then select the temperature. It holds within +/- 2° to 3°. No messing with programing of off/on, different temperatures, times and then having to do it all over again after you have made a manual change. Good for folks that have trouble setting the correct time on their VCR. Would be better if it had a back lighted LCD. Much better than the old mechanical thermostat.

I replaced one of the old round bi-metal spring thermostats with the Honeywell RTH111B. The Honeywell works great and keeps the temperature where I set it. It has no "bells and whistles" as you'd expect for the price. Only thing I did not like is that the slide switch for Heat-Off-Cool is quite small and it's not always obvious at which position it's set.

1.0 out of 5 stars Won't operate below 32 degrees - HUGE design flaw, March 13, 2011

I purchased this unit as a recommended 'garage thermostat'. I installed it for sporadic operation of my garage heater, during the winter in North Dakota. Needless to say it gets cold here, which is why we need a heater. But I also don't intend to waste the power necessary to keep my garage above 40 degrees all winter so would only use this on occasion. Onto the design flaw that I still can't believe...

This unit will literally not operate below 32 degrees. Going in, I knew it was only programmable down to 40 degrees, so it would not maintain a temperature of less, but since I only planned to use it sporadically, that wasn't an issue. The problem is, it won't even turn the heater on below 32. At all. I confirmed this was intentional design by Honeywell, which makes me seriously question the engineers they have designing their products. Not only that, they don't offer ANY thermostat without this flaw. Imagine, a thermostat for a heater that makes it impossible to heat because it's cold...umm...really? The old $3 Hg-filled manual junker I was replacing with this worked just fine below freezing.

Let's look at scenario 2: I lose power at my house for an extended time and it gets cold. When the power finally comes back, I can't turn my heater on to finally heat my house because the thermostat says 'nope, it's cold, no heat for you'. Honeywell's suggestion? Wait until it gets above 32 on its own, then I can run the heater...so basically, you can heat if it's already warm, but not if it's cold.

Sorry, a-returning this product will go.

Otherwise, if you're looking for this in a completely different application....The unit was easy enough to install. The directions weren't great, but they don't have to be. Any typical homeowner should have no problems. Unit looks good enough, and for the 5 minutes I played with it after install it worked well enough (I'd heated my garage so it actually worked for a few mintues).
