CUSTOMER REVIEWS

Rated 4.7 out of 5 by 67 reviewers.
Rated 5.0 out of 5.0 by Accurate as expected Very Easy to install for my HVAC system. I love the auto change over feature for when it is cool at night and warm in the day I set the temperatures to what I want it to be at and don't mess with it. February 3, 2015
Rated 4.0 out of 5.0 by Simple to install and even simpler to use. As an older couple who try saving money by DIY, I found this product very easy to install and to my real surprise, as advertised,even easier to to operate. No confusing programming requirements. Great for an older person like myself. Want it cool,turn on cool. Want it warm, turn on warm. Its that simple and really does work. August 7, 2013
Rated 5.0 out of 5.0 by Great Product The thermostat was easy to install. It keeps an accurate temperature to within 1 degree. I wanted non-programmable so it would be easier to operate but I also wanted a backlit display model. This one has both features. There's also a removable battery holder for easy replacement.

Rated 4.0 out of 5.0 by Good thermostat value that's easy to read I was tired of mechanical thermostat switches that last just one season and then fail. I figured a digital solution would be more reliable. It installed easily in under 20 minutes. So far it has been working very reliably. February 3, 2015
Rated 5.0 out of 5.0 by Easy Set and forget - Automatic Switch from heat to cool Good documentation for easy install of heating and cooling control. Very simple to set up for auto switching between heat and cool. Set "heat" to turn-on temperature ( eg: 70 degrees) Set "cool" to turn-on temperature (eg: 74 degrees) Now your home will heat when temp is below 70, and cool when temp is over 74. Could not be simpler! Only restriction is that heat and cool setting must be at least 3 degrees apart (with cooling set to the higher temperature). January 22, 2013
Rated 5.0 out of 5.0 by Simple is better Our previous high-tech programmable thermostat sometimes failed to turn on the heat in our high-efficiency gas furnace. For a while we tried using the previous thermostat's "hold" feature for a constant temperature 24/7, but even so on some mornings the heat would be off in the morning and I would have to reset the furnace by turning its power off and then on again. So I purchased this thermostat, a non-programmable style, and installed it in place of the programmable one. I had to drill one hole in the wall, since the screw holes did not quite match the spacing in the old thermostat. Installation was easy, about 45 minutes, including reading the instructions and labeling the wires with the letters on the existing terminal connections, using the handy stick-on labels included with this new thermostat, and then connecting the wires to the corresponding lettered terminals on the new thermostat. The new thermostat has been working fine since I installed it a week or two ago. Having a constant temperature 24/7 is fine for our family, since someone is home at our house nearly all the time, and lowering the house heat temperature at night for the six hours or so when we are all asleep was not much of a saving, since two of our family members like to sleep in warm rooms and were using electric space heaters at night. Now those electric space heaters do not have to be on as much in those bedrooms. October 21, 2014
Rated 5.0 out of 5.0 by Very easy to Install. Installed this on a very old AC/Heating system with gas furnace. It had a very old thermostat. I think original one from 1970's when house was built. Had no problem getting the wires hooked up. Took me a total of 30 minutes (mostly because I kept triple checking everything), and everything is running fine. It's been one month now.

Rated 5.0 out of 5.0 by Works perfectly and very simple to operate I purchased this digital non-programable thermostat for my elderly uncle who did not want to deal with the set up of the more common programable type thermostat. This unit has a digital readout which eliminates the guesswork of setting the old slide bar type thermostat to the desired temperature. Up-down arrows set the temperature. Works for both heating and cooling. Easy to install. SImple to operate. Perfect. November 12, 2013
