Customers say

Customers like the ease of installation, performance, appearance and temperature of the HVAC control thermostat. For example, they mention it works well, looks good and that the daily program I set works flawlessly every day. They appreciate the sleek “glass” interface and that it can set temperatures on the fly. That said, they find the readability super easy to understand.

I purchased this thermostat to use as a programmable thermostat for a gas furnace. I used it to replace a more expensive programmable thermostat by Lux that failed due to a faulty on/off switch. In my opinion, this is a better thermostat. I'll give you a few tips for programming it that I found useful. I'm only using it to control a heater, so I cannot comment on how it works for A/C.There is a hidden advanced system setup mode with some settings which will allow you to tweak the thermostat to its environment.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.When mounting the base, keep in mind that the front of the thermostat is slightly wider than the base. If you are mounting it in a corner, you'll need to account for this increased dimension.I think this is a good thermostat for the price. It's much better looking than the grey plastic 90's looking thermostat that it replaced. The display is large and easy to read and it is simple to program the start/stop times. I would recommend it if you are looking for a reasonably-priced programmable thermostat for a furnace.

5.0 out of 5 stars Excellent Thermostat!
Reviewed in Canada on July 15, 2022
I was looking for a new thermostat with a bright bold display that's easily programmable for both heating and cooling for a 120V system. This item exceeded all expectations. Easy to install using existing behind-the-wall wiring. The pre-programmed settings worked perfectly, and I simply had to adjust the temperature settings and convert from Fahrenheit to Celsius.
