Heagstat 5-1-1 Day Programmable Thermostat for Home Conventional Single-Stage Systems, up to 1 Heat/ 1 Cool, (with White Backlight)

With so many different thermostats that's available I was glad I chose this one. It was very easy to program once I put the batteries in it I was able to actually sit in my chair and program it without having to stand and do it by the wall where I mounted it. It was very easy to install the wiring diagrams were perfect. I like the size of the LCD display it works flawlessly I couldn't be happier especially at the price point that I purchased it for I would highly recommend this unit for anyone looking for a quality thermostat replacement

Not the easiest thing to install but any handyman can do it rather easily, just take your time, take a picture of the wiring on the old thermostat before dismantling. Easy to program. It came same day when I really needed it. Affordable. You will not be disappointed.

Easy to read screen lights up with a tap of a button. All the features work just like they should.

Easy to install and setup. A great product! I did have to calibrate the thermometer it was off 3 degrees but was super easy to do through the setup and keeps perfect temperature. Love that I could take it off the wall and set it.

My old two heat stage Honeywell thermostat no longer always energized the heat, must have been a problem with the relay contacts. Looked for a replacement 2 stage thermostat and found this one. Although it is not the latest WI-FI enabled, it does what is needed. It is programmable for MON-FRi, and SAT and SUN. The nice thing is that there are adjustments for temperature calibration, cycle rate, and more. (The Honeywell was known for short cycling). There is no info in the book as to when the second stage heat is called on, but it seems like if you are more than a degree below the set-point the second stage is enabled, when the second stage is called for the number +1 appears above the heat symbol. Another nice thing is that it is powered from the heater but also has battery back-up, not like my old Honeywell that did not have battery backup, so with a loss of power I needed to reset the time. I did inquire to HEAGSTAT as to when the second stage was activated, as at one point it seemed like it was always calling for two stage heat. Their reply was disappointing, basically saying to hire an electrician. I would have liked an explanation of how the second stage is energized and info that when it was energized the +1 would appear. The manual also shows a +2, who knows what that is for as there is no info in the booklet. The thermostat so far seems like a great deal for the money, works well and has many adjustments, and is for two stage heat and cooling. I give it five stars, although the customer support was disappointing and a bit insulting.

Just got this, programmed it and tried to hang on the base plate. It wouldn't seat; something was in the way in the middle so either the top or bottom would click, but not both. I realized it was the screws that are provided for installation. They have domed heads. Flat head screws solved the problem. See the picture. The unit is workin well so far.

This thermostat was easy to install. And it has a nice look. It's easy to program too!

First off it works but it's an unnecessarily frustrating process to set it up. The instructions as shown with diagrams both on this page as well as those included in the box are a mess. The connection points/wiring points is not for this device. Most of the connections shown do NOT exist. I ended up using the lettering and ignoring their placement. Thankfully our system is just a two wire heat only. It'd been awful if there'd been more wires to guess where those would've gone to. Next the instructions i received didn't show anything about batteries. On the lower front is a flip down panel. Place two aaa batteries there. As for setup i got stuck yet again due to those terrible instructions. They say to start programming to press the menu button. Wrong again, you need to press that button 2X before the display shows settings not a single press. Last issue is temperature. It isn't calibrated correctly, both of ours display room temperature 3.5F too high. So for example if i want the heat to come on at 70F it needs be set to 73F or 74F. FYI we have a couple indoor thermometers besides our echo devices that all measure temperature accurately. Using those confirmed the discrepancy. Once getting through all that the thermostat does do what i wanted it to do. All said knowing what i do now about this product i doubt I'd purchase it, them again. There are just far too many careless sloppy mistakes in the instructions.

2 wire/single stage heat, was a breeze to install. Instructions are a little difficult to follow, but programming was mostly intuitive. I like the large display with backlight when you need it. Will run entirely on 2 AAA batteries if needed, no external power supply required. Multiple programming options for heat/cool. This was a good purchase.

Great and worked as expected

The instructions were a little difficult to read for a first time novice woman like me, but it wasn’t hard to install and test within the hour. Good product at a reasonable price.

Multi stage thermostats are harder to find than I thought. After a couple of winters of having issues with the original thermostat, I got this and as soon as I read the instructions and hooked it up myself, it has worked as if it came with the furnace. Shipping was a little slow coming from the US, but overall, I'm very happy.

I only have a two wire system and it took a few tries to get it hooked up to the correct contacts because the instructions weren't super helpful. Otherwise great.
