Review: 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!
Review: 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.

## Questions & Answers

**Q: Is the font really large? i can't read below "10 pt";  prgramming is impossible on current model**
A: It doesn't seem the AM/PM indicator is a sensible size -- which seems to be a problem on just about all thermostats. The Honeywell's for example is just over 1 mm high (1/25th of an inch -- totally ridiculous) Note to manufacturers: It does actually matter whether it is AM or PM. The M is redundant. The text could have been twice the size without any other changes. But it should be the same size as the time characters. It is just as important to know AM/PM as the time. Please explain why anyone would think otherwise, and how anyone came up with the current mess of product designs. There is no reason to make it impossibly small to read. Functionality is key to design. Being able to read it is a pretty basic required functionality.

By the looks of it, you will almost certainly have problems trying to figure out which half of the day you are programming it for. Sadly, there appear to be no viable alternatives.

**Q: does it need to be reprogrammed when the batteries are replaced**
A: You will need to reset the time and date, but no reprogramming is required.  All programming and settings are stored and retained in the event of battery replacement.

**Q: is the back light on all the time?**
A: no, back light turns off about 10 seconds after last button is pressed

**Q: Does this offer a "swing" setting that will undershoot or overshoot the set temp?**
A: Swing problem. When I set the temperature to 71 the thermostat will reach 71 but it does not stop testing. The flame Icon will remain on for 3-5 min and it keeps heating. Making the other rooms heat up to 75-80 . I used this unit all summer long for A/C and it worked great. If I set it to 72, when the temperature of 72 was reached the unit would stop cooling at 72. The cool Icon would turn off at the set temperature and the system would stop cooling. Couldn't be happier with it for cooling . Love thermostat, just need to figure out how to make it work better for heating,

### ⭐⭐⭐⭐ Good value for the cost
*by E***A on April 12, 2021*

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. OFFSET I 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 START I 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 TYPE Set to "F" for furnace, "HP" if you have a heat pump. MINIMUM CYCLE PERIOD According 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."
