Rated 2.9 out of 5 by 33 reviewers.
Rated 1.0 out of 5.0 by Garbage, but what other choices are there? On my 3rd one of these now. Other reviewers are absolutely right that the temperature on the thermostat is never correct with the actual temp. Always off by 10+ degrees. Last one stopped working in the middle of the night (where my <1 year old sleeps). Took it out to see one of the terminals was completely burnt (pictured). This unit had only been in use for a little over a year (winter months only). The main issue I have is finding another option. I can't seem to find any 4-wire 240v electric thermostats. Maybe I'm not looking hard enough, but the bottom line is that these are awful products, and not reliable at all. December 10, 2014
Rated 1.0 out of 5.0 by Extremely disappointed Have older model of this type of thermostat (not same model #) in all rooms in my house since 1966 when house was built. They are all working fine yet, except 2. Electrician replaced one with above model one year ago, and it worked about 6 months, and then it blew, making the room an inferno (glad I was home at the time). Purchased another one and had electrician install it about a month ago also, and if you want 68 deg., you have to set it at about 72-73 deg. Why can't they be made like the old faithful ones that lasted 40+ years???? Let's see how long this one lasts! Please, Honeywell, make this product into something to be proud of and trustworthy!! Let us know when this happens. March 2, 2015
Rated 1.0 out of 5.0 by JUNK-same experience as BoBC's review (from 1/28/13) I had the exact same experience as Bob C (see prior review from 1/28/13) and have gone through 2 of these over the past year. They work okay for the first few months but quickly become very unreliable and you have to turn the dial progressively higher to get the desired temperature. I also called Honeywell and they are particularly unhelpful. I disassembled the second unit to see if I could diagnose the issue. It appears the contacts that comprise the switch inside become corroded after many on/off switches (each of which appears to generate a small electric arc) and the contacts begin to act as a resistor and generate internal heat, which then turns off the thermostat before it reaches the desired temperature. Solution: I've replaced the second unit with the White Rodgers 1A66 thermostat (I only found it online-quite a number of sellers; Home Depot unfortunately doesn't seem to carry it in stores or online). It appears to be working perfectly after several months. September 22, 2013
Rated 5.0 out of 5.0 by Would recomend to a friend. The manual electric thermostat I purchased for my wood burning pellet stove performed excellent. It was easy to install and looks great. March 24, 2015
Rated 1.0 out of 5.0 by last 3 to 6 years. pathetic I replaced all of the thermostats in my house for cosmetic reasons with these because the old ones were decades old and now 6 years later half of them have already failed. I'm real disappointed in how down hill the quality has gone and will do some more research to find ones that should last longer than a few years. March 14, 2015
Rated 2.0 out of 5.0 by First one fried after five years I purchased this thermostat as an exact replacement for one that stopped working after about 5 years. There weren't really any other good options available for immediate pickup. I have about 8 others that are still working but, based on the other reviews, I will probably have more fry over time.

Rated 5.0 out of 5.0 by Works My electrician called to Gary, and he knew exactly which thermostat, to get for me. It works fine, as far as I know as it was put in a rental house, and have not had any complaints, about it Thank Gary, for both of us. March 1, 2015
Rated 1.0 out of 5.0 by Junk I've now gone through 3 of these thermostats in the three years I've lived in my house. They are accurate when new and first installed, but by about a year later they are as much as 10+ degrees off . . . in other words, I have to crank it up to the 80 degree setting to get it to call for heat at 68 degrees. When I've called Honeywell about it, they just tell me they've never had this kind of complaint and direct me to warranty service. January 28, 2013
