Honeywell Home programmable thermostats are easy to install and are pre-programmed for your convenience.

We had one of those Commercial grade Honeywell touchscreen thermostats that usually do a great job, but we noticed the temperature in the house never seemed to keep, and would hear the unit, whether heater or ac, kick on quite a bit. We decided to do some research, and with a deal from our energy provider, we ended up with one of those $249 Nest thermostats. I was STOKED, like a fat kid with some apple pie. We got the Nest in, and I went to work. Like a Dad in bad joke bookstore. I've replaced many thermostats over the years and the Nest was a piece of cake. BUT, we discovered it had a malfunction, so after talking with tech support, it was getting replaced. SOOOO, back to the Honeywell. I went out to the garage and grabbed the oldie off the shelf, and as I was walking in, my Dollar Store flip flop got caught on the door jam. It popped the rubber thing out of the foam bottom and made me nearly fall over forwards onto the hard tiled floor. There i was, Rambo faced, screaming in slo motion, feeling the pain of my big toe hit the metal, when all of a sudden the Honeywell touch screen goes flying out of my hands, and flips, and turns, and swings, and screams, to the floor. BAM!!! Cracked screen. Out of Commission. No Goodie No More. Mad me. I dropped the ball, but it wasn't the ball man, it was my $150 Honeywell touch screen I had plans to put back onto the wall when we sold the house years from now. So there I was, at a cross roads, like Willow, but without Mad Mardigan there to take the baby. I broke my working thermostat, and was left with TWO broken thermostats. It was humid, then cold, then hot, then cold, then humid, the windows were open, they were closed, they were damned like Conan the Barbarian was.
I decided to order THIS thermostat from Amazon. I got in two days, and the hookup was easy. Easy yo. I'm talking so easy, I thought about taking it for a drink and a meal. The thermostat works like a champ! However I now rec'd the replacement Nest thrmostat and this one is taken down, boxed up, and awaits its new homeowner in severla years whoever and whenever that may be.
Pros:
1. Easy to install (C wire is Common and NOT used)
2. Basic use makes ti fun for all ages!
3. Basic programming is available, but nothing that is 3 pointer at the buzzer wow
4. Small, and easy to use
Cons:
1. None. It works great and is easy to install
Installation says "15 minutes or under" and I found this to be true.
To install:
Turn off power to furnace and thermostat (although it is a low voltage feed, you MUST still do this)
Unscrew the original thermostat from the wall but leave wires attached
Check the color of the wires and which terminals they attach to on the original (look for small letters W,R,Y,Rc etc)
Mark the wires (if needed) with the stickers provided in the package
Unhook wires from the original
Remove backing plate from new thermostat, thread wires through hole and place against wall
Attach backing plate using screws and wall plugs provided
Put 2 x AAA batteries(NOT supplied)in the faceplate
Attach previously marked wired to the matching terminals at the back of the faceplate
Snap faceplate onto backing plate
Read instructions for setting time and programs
Turn power to furnace back on
Pros: cheap, easy to install, good instructions
Cons: would have been nice to include 2 x AAA batteries
Overall a good buy. I fitted one as a test and then bought 3 more.
Top reviews from other countries
1. it is Fahrenheit only (I am used to dealing in Celsius) but it was easy enough to convert my usual settings back into old school.
2. there is no backlight to the display, and the display is small, so it is hard to read even with the ceiling light on.
3. removing the cover to install/replace the AAA batteries is VERY difficult. I expect it could be easy to break the cover in the attempt when it comes time to change those out.
But it works well, was easy to install & program (aside from installing the batteries) and looks neat and clean.
