Honeywell Home RTH221B1039 1-Week Programmable Thermostat

This arrived quickly. I had no issues installing it even though my home has older wiring-it was built in 1930. I previously had an ancient thermostat-one that used mercury. Installing this newer model thermostat has been great. It keeps the temperature steady & can be programmed when you know you’ll be away from home awhile. It was inexpensive, yet it works great.

Heat, cool, fan. Temperature up or down. Basic good thermostat, do not set a program on these its annoyingfor techs... Use for basic units. Only can use with single stage forced air units or heat pumps but only without auxiliary heat. If you aren't sure you have auxiliary heat you do if your energy bill is really high in colder months ( kind of a joke there ) auxiliary heat is at the furnace and is pretty much a heating coil that a dryer similary. It's a coil that gets red hot when your heat pump can not keep up helping heat your house it is similar to emergency heat. Anyway this thermostat is easy to install and is a good basic thermostat for your house. I buy these frequently for side jobs. If they want to upgrade to a fancy wifi remote activated thermostat down the road I will also install those but they definitely have more issues in my experience anyway. Recommend if you are good with walking to your thermostat to adjust the temperature of your house

I have 2 of these in my home they are easy to program, easy to adjust, and work very well. I wish they were backlit so you could see them in the dark and better during the day.

Easy to install and looks nice. Replaced an old thermostat and it’s really nice to be able to set temperatures for different times of the day. Good features for the price point.

This is programmable thermostat works as it should. This installation is very easy, less than 5 minutes connect it. Instructions are provided and are easy to follow. It is small and the screen is small and it is not backlit. It does everything I need it to. I would recommend it for the price point. You can’t beat it. I am not an electrician or A/C man, easy diy project.

Easy to install and works great, material seems a little cheap but as long as it works I'm happy

Old thermostat stopped working. I received the replacement unit in three days. While the defective unit is also Honeywell it is an earlier model. I removed the faceplate on the defective unit and did the same with the new one. I checked to verify the old and new models were wired the same and they were so I didn't remove the wall plate on the old unit but rather snapped the new faceplate on it and it works perfectly.

There was nothing wrong with my old thermostat except that it didn't indicate the temperature in the house and it needed electricity to operate. I bought this thermostat because it was inexpensive and I wanted a battery backup model so I wouldn't be without heat if the power goes out. I liked that the display was an innocuous gray instead of glaring green or brilliant blue like other thermostats.After having to read the manual to figure out how to set the thermostat to a constant temperature - something I think should be pretty easy to do without reading a manual, I found that this thermostat turns my heater on before the temperature drops to the programmed setting, then it runs the furnace constantly compared to my old manual thermostat set at the same temperature. With this thermostat, the heater runs and runs for approximately 15 minutes at a time (compared to my old thermostat that only ran my heater a few minutes). When the thermostat finally turns the heat off, it registers much higher than the temperature I set it to. If I lowered the setting, my house got much colder than I was used to before my heater turned on and my house still got way too warm by the time the thermostat turned my heater off.Why should I get uncomfortably cold because the thermostat doesn't kick on, then have to pay to heat my house to an uncomfortably warm temperature? I could tolerate a thermostat that is off by a degree or two, but heating to more than 5 degrees above the set temperature is not acceptable. If I had kept this thermostat, I'm sure my heating bills would have skyrocketed.Plus, I had to pay my handyman to install this piece of junk and I had to pay him to uninstall it and reinstall my old thermostat. Now that my old thermostat is reinstalled, the heater runs way less frequently than with this thermostat AND the temperature in my house doesn't fluctuate between being too cold and too warm.I definitely won't be buying another Honeywell product in the future.
