Ratings & Reviews for Honeywell Home RTH221B 24-Volt Basic schedule Programmable Thermostat

Works, but very hard to program.

As a thermostat, it works. That's about all I can say for programming is extremely difficult without a bright flashlight, making the text visible.

won't shut off at proper temperature

Set thermostat at 73 degrees. Temp go to 74 degrees. Air conditioning turns on. Temp hits 73 degrees but air conditioner stays on until the temp reaches 72 degrees. The heat part of the thermostat works the same way!

Needs background light

I’ve had this thermostat for about a year now. I original had a nest thermostat and while I really liked it, it would not stay connected to my phone. I think I kept zapping it with static electricity and it would make the Wi-Fi part in it go out. So I just bought something simple. I’ve read a lot of the reviews and I have not had any of the issues others have had from what I remember setting it up a year ago it was fairly easy. my only issue with it is there’s no backup light and I can’t figure ...

Worst

Very very confusing. I cannot turn On AC when i want. Such an irritating setup this system has. When I want to change the temperature the screen is locked and itdoesnt allowmw to change. Oneof the worst thermostats i have ever used

It does not have a back light.

It was easy to install, and works well.

Not easy to st up

Nice looking Very hard to figure out the dimplest form kf the wiring so i could get get to work. I can always get wlectronic things to work so i will return it

Sometimes, less is more

Excellent, works perfect & easy to install

Lowe's resell faulty thermostat

It makes sense that this was marked down cuz many people probably brought it back and you sell it as a final sell and no one can return it so y'all still win and we still lose when we originally lost out when we needed a thermostat so here I've spent $29 on the thermostat just to have to turn back around and buy a new one that actually works. This thermostat the first day that I put it on was at 90° when I put it to 70 when I try to put it down it only stays up in the 80s every time I put on thi...

Difficult to Navigate

Had to look up YouTube videos to make a temp stay that temp until you change it. Woke up and the heat was off and nothing was set after i set it 2 days before that. Spend a little bit more money and get one that is non programmable and just has arrows and set button

Make sure you read the instructions thoroughly.

My gravity system is working so much more efficiently.

Buy anything else, seriously

Horrible!! I had a programmable thermostat that worked great. I got a new boiler and they gave me this one. To say I hate it is an understatement. This thing is unnecessarily difficult to use. Every aspect goes against you. It only lights up for a couple seconds when you touch it so, when you are attempting to change anything, you have to do it quickly or use a flashlight. It makes you go through everything to change any settings. This thing is so bad Honeywell should be ashamed! I am guessing ...

thermostat is great

I have had one for years for heat in one area of the house, never had an issue with it. Replace battery once a year. Going to go buy another one today for another area of the house
