Rated 5 out of 5 by from I forget it’s there This Honeywell thermostat (RTH221B1039) has been in this house probably since when they first manufactured this model (I bought the house in 2019, manufactured home built in 1996). I’ve had to change the batteries only once since 2019 to today. I keep the temperature set (heat) at 65 F entire winter, 75 F (cool) for entire RTH221B1039 spring/summer/fall; that seems to give me the best rate on electric bill usage. I have kept the programmed days/times 3 or so degrees cooler/warmer when most people are gone during the day or asleep. I’ve seen many customers writing reviews based on negative experience. Is it due to the wiring during install? Is the type of HVAC setup correctly (my switch on back/inside thermostat has switch for OIL/GAS or heat pump). Also, my model is very specific that heat pump without emergency backup is not compatible. I cannot comment, and only speculate like I did above because I have not had those issues. I can share my setup: heating/“furnace” is natural gas, intact and original since 1996. The air conditioner is a huge green metal box outside of the house (commercial grade). Strangely enough no problems at all. I don’t know if this thermostat “plays better” with certain models of HVAC units? Now, having said that, I am going to “upgrade” and buy the WiFi version of this thermostat because it’s the simplest WiFi thermostat where I don’t need all bells and whistles, nor my life/privacy/soul sold forever online. I’m getting this other thermostat, along with the Honeywell security (locking) cover, because I’m tired of people constantly changing/messing with it when they’re clueless as to what they’re doing. But, I will still keep this old model as a backup (perhaps as an alternative wiring setup I can quickly switch over to).

Rated 5 out of 5 by from Great! I bought this product 5 years ago and never had a problem with it.

Rated 2 out of 5 by from Six month terminated Pro installed about 6 months ago, 2020, and last night we had a power outage. This apparently caused the thermostat to reset or wipe all settings. Following instructions in the manual, VERY small print, attempted to reprogram the box. Looks like it took the imput but NOT WORKING HEAT. Reset furnace switch and reset thermostat program waited a few minutes, about ten, and turn on furnace. Blower runs, NO HEAT and at 6 degree F, it is cold.

Rated 1 out of 5 by from Program This has a mind of its own! Do not follow the schedule. It is not supposed to to be awake till 8am and it will start kicking off at 6am or so!

Rated 1 out of 5 by from Lousy I bought this thermostat a week ago and it has yet to follow the schedule I have set. It can't even respond properly to a temporary setting, which is basically asking it to run manually. I have never had such a poor thermostat. This will be going back to the store today.

Rated 1 out of 5 by from Worst Thermostat EVER Have had this product over a year and do not have one good thing to say about it. Started having problems right after purchase. Waking up to freezing temperatures when settings are all correct, this thermostat does not regulate heat or respond to temperature changes in the home.

Rated 1 out of 5 by from does not function as a thermostat does not turn on heat at set low temp, or keep heater on until set temp is reached. carefully programmed for all scenarios (weekday, weekend, day, night, evening, etc). But would only attempt to start heater when power switch was moved to OFF, then back to HEAT. Simply does not work.

Rated 2 out of 5 by from Not good for the long haul Bought this a year ago and worked fine. Now it’s not sticking to the schedule. For one evening (home from work) programmed time, it heats 90 minutes early. Everything is programmed correctly, didn’t happen first season ‘heat’ was used. But we just switched over from AC to heat and it’s heating too soon for this setting every day. Who knows might be doing the same for another setting but we are asleep during the first heat up period.

Rated 1 out of 5 by from Terrible No wiring procedures for an old 2 Wire hookup. No help from support.

Rated 4 out of 5 by from Works exactly as promised If you follow the instructions this thermostat works great - it does exactly what it promises to do (one program for the entire week). My only complaint is that the batteries are required for it to work, not just to provide backup in case of a power outage.

Rated 4 out of 5 by from No Complaints I bought this thermostat to replace an older round one which was not programmable, didn't even allow me to set different day/night temps. I got this installed by my electrician. It is pretty easy to program -- you can set a weekday wakeup/leave/return/sleep schedule, and then Saturday and Sunday separately. I believe we've lowered our fuel costs by having these settings automatically made. I just replaced the AAA batteries for the first time -- very easy.

Rated 1 out of 5 by from This thermometer is the worst. This thermometer is the worst I have ever seen I live in NV when it is 100 outside the a/c does not come on. I bought an a/c was to make the room cool. It is hot. We keep the blinds shut. Still hot. Doesn’t come on when it should. Piece of garbage. If I could give it a negative five stars I would

Rated 1 out of 5 by from Horrible product!! I moved into an apartment that has this thermostat and it has been a nightmare. First there was no manual provided by landlord and then trying to find online was impossible cuz it kept pulling up other models or trying to locate a retailer. It says how to set current time and day but apparently day isn't important cuz it skips and goes straight to programming which I wasn't trying to do. And it seems impossible to set a weekly schedule when you can't change for weekends since no day available. I also have never seen the low battery light and went out of town for 2 weeks in the summer in Phoenix and it died. I came home to a 97° house at 1030pm. I had to wait hours til cool enough to sleep and had to throw out lots of baking products since they melted. Really hate this system and would not recommend to anyone. Unfortunately I don't have a choice.

Rated 1 out of 5 by from Worst Thermostat EVER This is the worst thermostat EVER. I try multiple times. It just does what it wants too and wont remove the previous setting. SET, HOLD AND RUN do not work and my room keeps getting warmer. DO NOT buy this item!

Rated 1 out of 5 by from Impossible to set I have re-programmed this thermostat a dozen times. I want it to start at 8 a.m. at 72 and quite at 4:30 to 78 - it comes on at 8, cools to 76 and shuts off. Worst. Worst Thermostat
