Tools and Hardware Reviews of Honeywell RTH230B 5-2 Day Programmable Thermostat

Customer Review: Not the best
Summary: 2 Stars

My first complaint is that it only lasted about 4 years. Then it started to get flaky, even with totally fresh batteries. I think the problem was probably some kind of loose connection. For a while it would only turn the thermostat on if you pressed down on the case where the batteries are. Then that stopped working. I spent a while seeing if I could find the source of the problem, but eventually I gave up and ordered a different model that comes with a 5 year warranty. I know some people will probably say that I should be happy with a 4 year lifespan, but I completely disagree with that throwaway mentality. Other than the controls, a digital thermostat has zero moving parts, and it ought to be able to last for many years. Anything less than a decade is imho unacceptable.

Even when it was working, though, I have a few complaints. Having to take off the cover to do something like change the program is a bit of a pain, esp. considering that the cover doesn't come off as easily as you might hope. Getting out the batteries is also a pain. (Wondering if I damaged the battery connection by having to force them out some time...)

But my biggest complaint is that when you change the temperature to a value other than the programmed set point (e.g. a temporary override), it does *not* last until the time of the next program change. I think it lasts for just 2 hours (I may be wrong on the exact amount). So forget about for example normally having the heater on during the day on the weekend, but lowering the temperature when you leave the house for the day. I ended up a lot more using this as a manual thermostat, but not even via temperature control -- if I left the house for the day on the weekend, I would just turn it to "off". Not that big of a deal in a place with a moderate climate (SF area), but this would be totally useless in a place with truly cold winters.
