Review: Fantastic deal for $$, EASY to DIY install w/ great video & app instructions. - I am impressed. First of all, watch the installation video in the item listing in desertcart. It is the first video for this Sensi Lite Smart Thermostat and it could not be anymore thorough than it is. If you want step by step it is that and logical. Then the app itself does the same thing, step by step as well. These folks actually cover all the bases. I know a lot about a lot of this but not AC and heating. It went off without a hitch, I have an old 4 wire system with no C wire and what is really cool is BEFORE YOU EVEN BUY you can d/l the app, go to the step as if you are installing a new one, go where you identify the wires on your old thermostat and it will tell you if it will work for you if you are not sure. I had this thing on, up, and connected to wifi and running in about 10-15 minutes, no issues. The only thing that concerned me was I was reading reviews before buying it and some people complained about it losing connectivity frequently. Only 3 minutes after installing that happened one time, and as I was reading the re-connect instructions it prompts you to, then it reconnected on its own before I could do it. For all I know that could have been my wifi burping, it does sometimes. >>IF<< I have that as a recurring issue I will be returning it because my router has plenty of reach and several devices further from it than this thermostat never lose connection. We shall see. I am just trying to give a full picture, I have no complaints but that was the primary reasonable one I saw in the negative reviews. So far I love the thing, the display is very cool, most of the time I will be bumping it manually walking by and that is a piece of cake. I have old eyes and appreciate the large numbers on the display too. I also like I can adjust it remotely from 4 states over as well. Honestly if you just want a remote app and basic functions with a schedule (I won't use) I don't know about all these others that cost way more why you would buy one of those. It is also nice looking. Oh yeah, it works on Alexa and other voice control things I also do not use. I think you get a lot of bang for the buck on this.
Review: Amazing smart thermostat that works with two wire heater - Works great on my old two wire (red and white) wire Pulse funace. Easy to install, connect to wifi, and I love being able to control the temp from my phone. My wife used to push our old thermostat slider up without being able to see what the temperature was actual set at, it had a couple second delay before it clicked so she would over shoot the temp and I would wake up sweating. With the Sensi Lite Smart Thermostat the room temperature displayed is easy to see and controlling temp from the app is super easy. I like how the display turns off while furnace is running but wish it had a dimmer feature for the display while showing room temperature as I worry it may eat through the two AAA batteries rather fast. Will have to see how long they last, but I am sure we will save a great deal on our energy bill with this amsome new thermostat.

## Questions & Answers

**Q: How does the auto changeover work? can i set it to keep the temp between 65 and 74 degrees and it turns a/c and heat on as necessary?**
A: Yes I wasn't sure how it would work.  I have my account set to 78.  AC came on when it go too hot.  Hope this helps.

**Q: Hi. My old thermostat has the red wire connect to RH which then jumps to RC. With the Sensi lite, do I just attached the red wire to R? Thank you.**
A: Sensi claims there is an internal jumper which means you only have to connect the red wire which now goes to RH. However, I had to pigtail the red wire and connect to both RH and RC

**Q: Will this thermostat work on a split unit meaning natural gas heat**
A: It works on my natural gas central unit (if you need emergency heat then no this touch lite will not work for you)

**Q: Does this have a child lock?**
A: Yes, it’s called Lock Thermostat Display. It’s located in the system settings.

### ⭐⭐⭐⭐⭐ Looks great, works even better!
*by A***R on January 11, 2026*

Super easy to install and program. No more fights over the thermostat! Easy to set up temps and a time schedule to reduce use. The touch screen is the best! We use it on auto to keep the house a constant temperature. The setting are far more accurate than our previous thermostat. The build is sturdy as well as sleek. Looks good in the room
