Honeywell 105841 TH4110D1007 Programmable Thermostat, 3-13/16" High x 5-3/8" Wide x 1-1/4" Deep, Premier White

This is a great thermostat. No frills, good price, easy to install. I originally ordered a different brand that looked a lot nicer, with a larger display, but had to return it because it did not work correctly. It also had no "common" terminal, which means that it will stop working when the battery needs replacement. Don't have to worry about that with this one. If you're looking for a thermostat that just works, is affordably priced, allows you to configure a schedule for weekdays that is different than weekends, look no further. It doesn't have WiFi connectivity, but some of us don't care and would rather spend the extra $100 on something else. Lord knows we all need the exercise to get us up off of our lazy bottoms more often. I wish the display were larger, but for the price and the other things mentioned I am willing to overlook that.

I bought this thermostat to upgrade the analog thermostat in my motorhome. The swap was very easy to make as the instructions were clear. Once installed (which took all of five minutes), programming the device was a snap. I wanted a unit that would lower the temperature before bed and raise it in the morning. This device does that and more. It has two main programs, Monday-Friday, and then the weekend. For each program, you can set a temperature for wake up time, the day, the evening, and the night. So if you work outside the home, the temperature would be allowed to drop during the day and then be brought up to a comfortable temperature at your return. It works perfectly and is much more sensitive than was the old analog unit, so I find that I'm saving on propane. My furnace runs more often, but for shorter bursts and the temperature barely fluctuates. One thing to be aware of is that if you set the thermostat to 65F at 8AM on Saturday morning (or whenever), it will guess how long it will take to get to that temperature and may start the furnace much earlier than that! I've come to program the thermostat to reach a certain temperature about a half hour after I want to get up so that the furnace starts when I'm actually ready to wake up.

I bought this to replace a previous Honeywell thermostat:[...]that went flaky on me after about 4 years.I was initially reluctant to buy another Honeywell, but after reading reviews decided that maybe this was the best choice for me. The convincing factor for me is that this is from the "Pro" line, so it comes with a 5 year warranty. Although I have no clue if that means that it's built any better or with any better quality components or not.I'm not really sure what makes it a "Pro". They don't actually intend for it to be sold to anyone but contractors, which is somewhat absurd imho. There are a lot of settings that I don't necessarily care about, and going through them requires a somewhat non-intuitive setup phase (that you probably won't be able to figure out without a manual). So maybe that's the reason. But once you have it set up, the basic operation (including changing program values) is reasonable simple and intuitive and just like any other programmable digital thermostat that I've used.I was a bit wary of the AIR (Adaptive Intelligent Recovery) feature, where the thermostat doesn't turn on when you set it, but instead tries to predict when it ought to turn on to be at the selected temperature at the selected time. Sounds like something that sounds great in theory, but might be flaky in practice. Esp. since one of the reviewers complained about it, as well as getting no help from customer service in trying to disable the feature. I decided that I was only going to buy the thermostat if this could be disabled. But the owner's manual gave no info about how to do that.So I called customer service. I got a reasonably helpful person who was not an idiot and could speak English. (And when I asked a question he didn't know the answer to, he didn't just make something up -- he put me on hold and found someone else that knew the answer.) Anyway, the bottom line is that yes you *can* disable this. While the owner's manual doesn't cover this, the installation guide does. While these both come with the thermostat, they are also both available online. The owner's manual is here:[...]Fwiw, selection 0 in setup function 13 turns AIR off.I can't speak to how well the AIR does or does not work, since I just disabled it during setup.So far it seems to work, although I don't really have too many things I'm looking for in a thermostat. (Although it does improve upon my previous model in various respects, like having a backlight, and having a more informative display, and not requiring removing the panel to program it, and actually doing the right thing when you set a temporary temperature by keeping that valid until the next program change.)I do have a few minor complaints about the physical design. I would like to see a few more holes in the backing plastic piece to give you some more options wrt where to mount the thermostat and where to run the wires. I had a few constraints relative to my existing installation, so I ended up using the existing left mount hole as is; ignoring the hole for running the wires; using the right mount hole for running the wires; and drilling a new hole for the second mount hole. Not a huge deal, but I could understand if some people would be nervous about drilling into the plastic. Also, I was able to run my wires through the small mount hole b/c I only have a 2 wire system. For a more complicated system, that might not have worked and I might have had to drill a larger hole.Also, it's a bit of an effort to remove the main unit from the base, which is necessary to change the batteries. I'm nervous that that will put excessive stress where the unit is mounted into the plaster. I guess I'll just have to try to be as gentle as possible.

I am delighted. My old thermostat had become almost impossible to use, because the raise temperature button had become "mushy" and rarely worked. I ordered this, which is the identical model, and I was able to simply pull the old one off its mounting, and place in new one. Works perfectly, just had to put in new settings. This will also save us money, as we can leave a low maintenance setting, and raise it only when needed. (PS, the old one was 10-20 years old. Thank you Honeywell for keeping the same model available. That made it within my budget and skill limits to replace.)

A couple of one star reviews said their thermostat lasted only 4 years and 5 1/2 years. Mine lasted 4 months! It stopped working 6/27 and I finally got a replacement 9/9. Of course I needed a replacement in the interim and that cost a service call of nearly $300. You have to do warranty requests through the parent company Resideo US. That was a frustrating nightmare. It was like pulling teeth to get them to honor the warranty. Twelve emails and almost 3 months later I received a replacement which, of course, will not be needed since I had a contractor replace the failed unit. But who knows? With their lack of quality control I might need it any day now. Never purchasing a Honeywell thermostat again.

Easy to install and works great. Exactly what I expected.

Shipping was fast. We had the same model previous. Easy to install.

Takes a bit to figure out the controls and all, but otherwise it worked fine for replacing a manual thermostat.

Great product! This thermostat was easy to install and program with the help of the instructions. It can display temperature in Fahrenheit or Celsius.

It works fine and easy to install.
