What Customers Are Saying

Customers overwhelmingly praise this thermostat for its straightforward installation and reliable performance. Most complete setup in under five minutes without professional help, appreciating the intuitive interface and lack of complex programming. Reviewers consistently describe it as a solid, affordable solution that works effectively for basic heating and cooling needs. The main drawback is the absence of a backlight, making the display difficult to read in low light—a limitation some say would warrant a higher rating if addressed. Despite this minor issue, most customers consider it an excellent value and would recommend or repurchase it.

Simple as possible.

I needed to replace a simple thermostat and this was about as simple as is available these days. No crazy programming or apps...wired it up, put in batteries and away we go.

Local ac repair guy said I could get a thermostat installed from him for $250 or go to Lowes and get one for less than $30 and he would walk me through installation. I didn't even need to call him back the instructions were clear and my AC is working fine again!

Simple, Reliable, Inexpensive

Would Recommend

My 25 year old Honeywell programmable thermostat was showing "bat lo" even after replacing with new batteries so time to replace. I don't use the programmable features; just set the temperature and forget it so I opted for the basic thermostat with digital temperature readout. I have used this model in rental houses before and it is very long lasting; only batteries need to be changed occasionally. Simply insert the wires to the matching color terminals, add a couple batteries, screw to the wall...
