Display very legible, and bright
Always used top brands for thermostats, this one looked very clear and bright display. Needless to say it’s working perfectly. Easy to install.

Beautiful, easy to read and easy to install. This is the one that has it all.
So, I bought this to replace the generic Honeywell thermostat I had been struggling with for years. ( Stupid little beige box with 2 toggles and one slider with an ambitious temp gauge. You know that bugger. And you hate it. Don’t feel ashamed. It’s a trash design. It’s ok though. Read on.)It’s getting to be that time of year again. I had a moment the other morning.Picture me. Groggily rising from my rest before the sun has even thought about starting this day. I emerge from my bedroom. It’s cold, because the day prior, it was warm enough to not need heat. So you left it be. Clever chap, eh?It’s Monday. It’s 345 in the morning. I knew 2 things about the day so far: it was cold, and I needed to take care of the morning board meeting.A mad dash down the stairs, clad in only the skin I was born with (and… the skin that grew to cover my growth, of course). A tight turn onto linoleum floors. So cold. A slap of the ol thermostat and then a rush to the bathroom.It didn’t have to be like this. I knew that.I had been holding out for my new thermostat. I had wanted one that had a full color display, iot abilities etc.But they were wantsI had needsAnd now we are here.I’ve only just installed it on my arrival home from work.As you can imagine, after a 10 hour day at the plant, there isn’t much I want to do but relax.I had a job though. 15 mins. One screwdriver. Done.Programming was super simple.Provided is a very well made booklet containing any information you might need for the device but yeahHere we goRank time. 1-10. You know the drillPackaging 9/10OI! That packaging was rugged. Absolutely beautiful presentation thoughMake a rip strip for easy access!Product Sexy/10Let me not mince words: This thing is gorgeous. It just looks great. Slick, clean and modern. NICE!Programming 10/10Responsive, easy to understand. This is some good stuff.Be up and running in 5 mins. Never have to touch the thing againThis is a good product. I’m buying another one to replace my other thermostat. Which is also a beige vague box

Good value for the cost
We’ve been impressed with the ease of install of this thermostat right out of the box. We were able to use the same anchor holes the old thermostat used. Unfortunately this thermostat sits lower on the wall than the previous thermostat, so we’ll need to do some spackling and painting to hide the exposed area (lesson learned – always remove the thermostat when you paint the walls). My 84 yo mother-in-law can be sitting 10 ft away on the couch and easily see the temperature w/o her glasses. The backlight only stays on for a few seconds after you’ve changed settings, and then it turns off, making the display a bit harder to read in a darker room.It would be nice if the programming had a 7 day setting for folks who don’t need separate programs for weekday/weekend. I discovered the “copy” function about 4 days into programming the settings, and this made it much easier to set up for my elderly in-laws. One annoyance I did find while programming it was the setting function times out pretty quickly while you are setting temps and times, so if you have to pause and think about what you are setting, it times out and drops you out of the function within 3-5 seconds – way too fast. I feared I had to start over for that day I was programming, but I found it would save whatever settings you had gotten through before dropping you out. Give the user 10 seconds before it drops out of the feature and I’d be much happier.I also saw some folks complaining about hearing a ‘click’ when the unit comes on. You can hear it, but it’s a muted click, and some folks might find that useful to know when the heat/AC is coming on.I see folks complaining about temperature ‘swing’ in their reviews of this unit, and another reviewer posted this very helpful info about accessing the advanced settings menu to address it (haven’t tried it yet myself), so I’ll copy his directions here in my review, too, as I believe this info is very important for folks who might experience this swing issue in use:”To access the advanced menu:1. Slide the MODE switch to OFF.2. Press RUN to wake up the thermostat and activate the back light.3. Hold the RESET button. (This button is on the back of the thermostat where you installed the batteries.)4. Press the SET button while holding the RESET button. (Do this fast! If you hold RESET for more than 5 seconds, it resets the entire thermometer to out-of-the box default values. If it does not work on the first try, release both buttons and try again.)5. Release both buttons in less than 5 seconds.You should now see screen that displays “offset” in the upper right corner. Press SET to cycle through the advanced settings.OFFSETI found it helpful to increase the temperature offset by a couple of degrees. My thermostat is in the hallway where there are no heater vents. By the time the hallway reaches my desired temperature, the temperatures in the rooms with the vents are typically 2-3 degrees higher than the hallway temperature.EARLY STARTI left this off, but you can turn it on to have the heat start before the programmed time. I just programmed the start time to begin 15 minutes before I get home.SYSTEM TYPESet to “F” for furnace, “HP” if you have a heat pump.MINIMUM CYCLE PERIODAccording to the user manual: “Changing the minimum cycle period to six minutes or greater enables smart logic.” Apparently the thermostat has some ability to learn the best cycle times for your system. They give a table in the manual for common cycle periods. I set mine to 12 minutes for a 1-stage furnace with an electric fan.”

Superb! I have nothing negative to pick on.
Over the years, between my home and business, I have installed many thermostats in the past, mostly replacing older Honeywells with newer Honeywells. This time around the issue was the 5-2 days thing, I really hated to drive to the business Sunday night after extended Thanksgiving weekend (when thermostats are lowered) just to reactivate the thermostats for Monday morning.With the “I am mad as hell and I am not gonna take it anymore” attitude, I looked for thermostats which can handle 7 day schedule. And I was determined not to buy yet another Honeywells.So I found these and ordered 3 of them Saturday afternoon, they were shipped Sunday evening, I received them Monday afternoon and installed couple hours later.Everything went flawless, all 3 installations without a glitch. If another reviewer complains about clarity of instructions, then I would not know because I did not read them, the design is so intuitive that instructions were not needed. The programming was so quick thanks to the “copy all” function. The units look beautiful, 21st century, just the right size and buttons. Big digits with high contrast ratio. 3 AAA batteries are better than Honeywells’ 2, higher display contrast, longer life. I have nothing negative to pick on. Well done!

It’s a nice, easy to use unit that is visually pleasing and simple to set up. It can be programmed in your hand, as opposed to mounted on the wall, which makes it less of a pain in the ass. The price is right too.

A very good product. Easy to install,, it took me about 30 min. to replace my old thermostat with this one.The instructions are clear. The display is easy to read even at night and the configuration is quite simple.

I installed this thermostat in less than 10 minutes. It was intuitive and directions were clear, only thing I had to look for in the manual was how to set the clock (turn the unit off then set).Overall I am happy with the purchase, although I wish the clock would appear larger when the unit is not in use, id rather see the time than the temp from across the room.

This is a great programmable thermostat, I’ve had it a month now and I’m very pleased. Even though it was my first time using one, the programming of it was straight-forward, as are the features. Now the installation… I took off one star because the instruction manual does not show *any* diagram or have any instructions for my wiring system which is a “2 wire system”. Grr. So I was completely lost until I stumbled across a YouTube video by some random guy that explained how to wire a new thermostat to an older “2 wire system”. Yay for that guy! Still, the thermostat itself is good and works great.

Worked great for 4 years, and then after the batteries died in the middle of the night, pushing my house eight degrees below normal, we changed the batteries, reset it and then my house shot twelve degrees in the middle of the day while my dogs were at home. And I cannot find the manual in the house.I cannot find it online, essentially, this thing is now garbage. Waste of money. Not a longer term use thermostat
