Your cart is empty.A simple, easy to use 1-week programmable thermostat. You set it up to adjust the temperature when you are away or asleep-times when you don't necessarily need to heat or cool your home to optimum comfort-and your HVAC equipment runs less. Plus, your heating or cooling comes back to the comfort level you desire before you come home or wake up. Honeywell Home programmable thermostats are easy to install and are pre-programmed for your convenience. For more than a century, Honeywell Home thermostats have been the popular choice of homeowners. This thermostat is compatible with single-stage heating/cooling systems, heating, cooling, heat pumps without backup heat, mill volt, pellet stoves and fireplaces. It does NOT work with electric baseboard heat (120-240 V), heat pump systems with backup heat or multi-stage heating/cooling.

It still works. I just want one that lights up when I push a button. It's in a dark corner and the light on the phone is a hassle when going to bed. I'll use more batteries for the convenience. I don't mind to FAFO. EV anyone? Now there's a massive battery.So ¼ oz of battery to control the heat where I live is perfect.Installation is easy.Two screws is all.Very simple.Great control.Wonderful display.

Good quality, easy to install (thanks to you tube) and program. Basic functions, just like I wanted. Be sure and get the model that illuminates.

It was easy to wire in. It's very affordable. It works great. It's a little tedious to program.

The only reason I give this 3 stars is because the title of the product is misleading. It says its a 1 week programmable thermostat, but its only a one day (repeats same procedure everyday) programmable thermostat.Overall easy to install, did not have instructions for a 2 wire installation. I had old wire where they were the same color, if you take a volt meter, whatever one is actually producing a current is the R wire. The other one without a current is the W wire. Wish they had something like this in the instructions. That was the other reason I gave it 3 stars.It works great so far, no issues. Will update in a month of this thing running for awhile.

Replaced all of our old spring coiled thermostats and it has made such a huge difference in the ambient temperature of our home. No more, lots of heat or not enough heat! We should have done this a lot sooner as this would have saved us $$$ in heating our house, not to mention being either too hot or too cold all the time! Husband found it easy to install but the instructions are a bit lacking for how to use the thermostat.

Hooked my pellet stove up to this thermostat. Works like a charm. Stove uses less pellets, I pay less for heating win win. Thermostat was easy to install and wire for two wire stove.

Got to replace an older 5/2 programmable thermostat which had started to act up (rubber buttons were sticking). Retired now so only need a one week program (every day is a weekend now!). This works very well, was easy to program, the mounting holes were even in the same place as my old one so no need to re-drill into the wall (that was a nice unexpected bonus). The only downsides are:1. it is Fahrenheit only (I am used to dealing in Celsius) but it was easy enough to convert my usual settings back into old school.2. there is no backlight to the display, and the display is small, so it is hard to read even with the ceiling light on.3. removing the cover to install/replace the AAA batteries is VERY difficult. I expect it could be easy to break the cover in the attempt when it comes time to change those out.But it works well, was easy to install & program (aside from installing the batteries) and looks neat and clean.

lo compre especialmente por su precio, era el mas barato digital en existencia, tiene función programable aunque no la uso, durante toda la temporada no tuve ningún problema, el único detalle a considerar es que no tiene luz de fondo, así que en la noche con todo oscuro no puedes ver el display, pero como este normalmente solo lo uso de día no tengo quejas

Here the deal:We had one of those Commercial grade Honeywell touchscreen thermostats that usually do a great job, but we noticed the temperature in the house never seemed to keep, and would hear the unit, whether heater or ac, kick on quite a bit. We decided to do some research, and with a deal from our energy provider, we ended up with one of those $249 Nest thermostats. I was STOKED, like a fat kid with some apple pie. We got the Nest in, and I went to work. Like a Dad in bad joke bookstore. I've replaced many thermostats over the years and the Nest was a piece of cake. BUT, we discovered it had a malfunction, so after talking with tech support, it was getting replaced. SOOOO, back to the Honeywell. I went out to the garage and grabbed the oldie off the shelf, and as I was walking in, my Dollar Store flip flop got caught on the door jam. It popped the rubber thing out of the foam bottom and made me nearly fall over forwards onto the hard tiled floor. There i was, Rambo faced, screaming in slo motion, feeling the pain of my big toe hit the metal, when all of a sudden the Honeywell touch screen goes flying out of my hands, and flips, and turns, and swings, and screams, to the floor. BAM!!! Cracked screen. Out of Commission. No Goodie No More. Mad me. I dropped the ball, but it wasn't the ball man, it was my $150 Honeywell touch screen I had plans to put back onto the wall when we sold the house years from now. So there I was, at a cross roads, like Willow, but without Mad Mardigan there to take the baby. I broke my working thermostat, and was left with TWO broken thermostats. It was humid, then cold, then hot, then cold, then humid, the windows were open, they were closed, they were damned like Conan the Barbarian was.I decided to order THIS thermostat from Amazon. I got in two days, and the hookup was easy. Easy yo. I'm talking so easy, I thought about taking it for a drink and a meal. The thermostat works like a champ! However I now rec'd the replacement Nest thrmostat and this one is taken down, boxed up, and awaits its new homeowner in severla years whoever and whenever that may be.Pros:1. Easy to install (C wire is Common and NOT used)2. Basic use makes ti fun for all ages!3. Basic programming is available, but nothing that is 3 pointer at the buzzer wow4. Small, and easy to useCons:1. None. It works great and is easy to install

I wanted a simple to install thermostat to replace the aging, mercury switched Honeywell items that control our heat and cooling. After researching I decided that a simple weekly timer is good enough, and certainly better that what we had originally. The RTH221B shows the current temperature and can be set to adjust the temperature when you wake, leave, return and night. It is simple to use with 15 minute increments.Installation says "15 minutes or under" and I found this to be true.To install:Turn off power to furnace and thermostat (although it is a low voltage feed, you MUST still do this)Unscrew the original thermostat from the wall but leave wires attachedCheck the color of the wires and which terminals they attach to on the original (look for small letters W,R,Y,Rc etc)Mark the wires (if needed) with the stickers provided in the packageUnhook wires from the originalRemove backing plate from new thermostat, thread wires through hole and place against wallAttach backing plate using screws and wall plugs providedPut 2 x AAA batteries(NOT supplied)in the faceplateAttach previously marked wired to the matching terminals at the back of the faceplateSnap faceplate onto backing plateRead instructions for setting time and programsTurn power to furnace back onPros: cheap, easy to install, good instructionsCons: would have been nice to include 2 x AAA batteriesOverall a good buy. I fitted one as a test and then bought 3 more.
