Description

A simple, easy to use the 1-week programmable thermostat. You set it up to adjust the temperature when you are away or asleep-times when you don''t necessarily need to heat or cool your home to optimum comfort-and your HVAC equipment runs less. Plus, your heating or cooling comes back to the comfort level you desire before you come home or wake up. Honeywell Home programmable thermostats are easy to install and are pre-programmed for your convenience. For more than a century, Honeywell Home thermostats have been the popular choice of homeowners. This thermostat is compatible with single-stage heating/cooling systems, heating, cooling, heat pumps without backup heat, mill volt, pellet stoves and fireplaces. It does NOT work with electric baseboard heat (120-240 V), heat pump systems with backup heat or multi-stage heating/cooling.

I read some reviews before I bought this. One of them said don’t get this one, because it does not light up, and it is not “one week” programmable, it’s one day, and repeats all week.

After getting the unit installed, I instantly realized that reviewer was correct. I immediately became to search for a better, more versatile unit. And i went to the store the next day and bought it....

And then it took me a couple days before I got around installing the new unit. In that time, I realized that no light was not a big deal-I had never had one that lit up before. And sure, it would be nice to be able to program different patterns for the weekend-but this one would work just fine. I returned the $27 unit to the store and kept this one.

It’s been a few months now, and I am completely fine with this unit. It runs perfectly, it’s easy to install and program. I gave it five stars because it is a very good product for its price. I give my self three stars for not spending the extra $10 and getting the next step up.

We purchased two Honeywell RTH221B1021/A thermostats – one for each of the two heating zones in our house. We bought them to replace old-fashioned analog-style thermostats that were hard to read and adjust accurately.

We are very pleased with our new thermostats. They were very easy to install; it took about twenty minutes to hook each one up. The digital display is easy to read, although it doesn’t have a back-light for viewing in hours of darkness. Programming the thermostat was a reasonably straightforward and painless procedure.

These Honeywell RTH221B1021/A thermostats seem to do a much better job of regulating the heat in our house than the ones they replaced. It is too early to tell if we will see any savings on our heating oil budget. I would bet, however, that we will.

There are certainly more advanced and sophisticated thermostats on the market, but they cost a lot more. For our needs, these simple and inexpensive Honeywell RTH221B1021/A thermostats are perfect. Highly recommended.

This is not a 1 week thermostat. It is a 1 day thermostat. I wanted to use this in a condo that I only use on weekends in order to save energy. Have the whole week at one temperature, and the weekend at another. Not possible with a 1 day thermostat. The picture shows this with a "Th" under the time (denoting that it can tell which day is which). The instructions tell you how to change the day. The box says it is a 1 day unit.

STAY AWAY!

Replaced this RV Dometic thermostat Dometic 3106995.032 Heat/Cool Analog Thermostat with the Honeywell. Did a better job of controlling the temperature. (I don''t think the Dometic thermostat has a heat anticipator.)

Bonus: The mounting holes even lined up.

The YouTube tutorials helped, and indeed, the power wire that went to the Dometic is not used.

The lack of a High/Low switch for the air conditioner is not a problem for us. I connected both fan wires to the same terminal so the A/C fan runs on high. May experiment with whether to change to Low only when we go back next summer.

Nice to finally have a thermometer in the RV. It''s accurate to within a degree or two.

Poor performance followed by malfunctions. The thermostat has only been run on the two double A batteries. For the first while it seemed to perform OK. It then started going through batteries quite frequently. Most recently it will turn the system on but then never reset. The system will run on heat or cool until you physically shut it off. You then have to take the batteries out of the thermostat as if to reboot the thermostat. It will then work properly for a few cycles until it goes back to where it turns the system back on and never off again. Under one year until failure.

Really cheap in every regard (including, I''ll admit, price). One good thing is it (barely) accepts 18 gauge thermostat wire which the brand I purchased previously did not. THE BAD THING...all the king''s horses and all the king''s men couldn''t make Honeywells sliding'' heat-off-cool switch'', slide again. One slide and that was it. Even the Rock would have failed to move it. I hate having to return things to Amazon. Maybe it''s because I''m a stockholder, but mainly, I don''t want to overuse the very generous return policy that the company provides. This was the second thermostat in a row that had to go back. I finally bought Amazon''s Emerson (which came with great instructions...although interestingly nowhere in the manual does it use the Emerson name, but it does use White-Rodgers over and over again). Anyway this Honeywell model was a bust AND I''m still stuck with trying to figure out what to do with the mercury that was in their old one that I replaced.

I gave it 2 stars because it accepted the gauge of wire that many older homes have and it did light up and with some difficulty, program. But the frozen slide switch and the cheap, cheap plastic which make up 95% of the thermostat (I wouldn''t be surprised if they haven''t also figured out how to replace the copper in the wires with plastic), is just mind boggling. My recommendation to Honeywell is to get their name off of these cheap thermostats because by keeping it there, they endanger their well earned good name. At the least they should brand these something like "Cheapostat by Honeywell".

10 minute easy installation, directions are very easy and simple. 10 minutes and this thermostat was up and running perfectly. Do not fear installing this yourself, just remember to shut your furnace power off. Needed a programmable thermostat for the main floor of our house, this one does the trick. Note that this particular model does not have separate programming for the weekend. Once you program it, that''s your program for the entire week, weekends included.

I wanted a simple to install thermostat to replace the aging, mercury switched Honeywell items that control our heat and cooling. After researching I decided that a simple weekly timer is good enough, and certainly better that what we had originally. The RTH221B shows the current temperature and can be set to adjust the temperature when you wake, leave, return and night. It is simple to use with 15 minute increments.

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.

Got to replace an older 5/2 programmable thermostat which had started to act up (rubber buttons were sticking). Retired now so only need a one week program (every day is a weekend now!). This works very well, was easy to program, the mounting holes were even in the same place as my old one so no need to re-drill into the wall (that was a nice unexpected bonus). The only downsides are: 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.
