Honeywell Home RTH8800WF2022, T5 WiFi Smart Thermostat, 7 Day-Programmable Touchscreen, Alexa Ready, Geofencing Technology, Energy Star, C-Wire Required

The media could not be loaded. i don’t know why it says that this is a frequently returned item, this is a great thermostat. we wanted something fancy, but not too fancy. once you get too fancy, things get too complicated and don’t work as they should... but THIS! this is the perfect fancy, but not too fancy, still easy to use and not complicated - thermostat! i love that i can control it from my phone using the app and set schedules for “away” and “home” times throughout the day to essentially have it not running, etc. it’s a great little unit! it’s also pretty, i love the dark screen and the touch screen. definitely a great and affordable asset to be more energy efficient! install was pretty self explanatory, just follow the prompts and answer the questions in the set up menu on the device. i think you’ll like it!

What can I say, it is a thermostat and it looks nice, I bought it for these reasons. I bought it in April of 2023 right after I had a leak repaired and the old thermostat looked very dated in a freshly painted room.It installed very easily and It really does look nice and new in the room. Once up I was pretty happy with it. I set a schedule and that's where the enjoyment stopped. As time went on I began to wonder if I had a leak or something, I had one in the past after all. It would not cool, and the temperature in the house would rise. I'd set it to 71 but the temp would slide degree by degree to 77 (which is what it was scheduled to hit at 11pm) and stay there for the night. Suddenly waking up freezing in the morning. The pillows in the bedroom were muggy and damp intermittently. Some days we'd sit at 77 degrees for no reason. The heat pump is running near 24/7 trying to cool the house....Luckily I am pretty DIY and troubleshooting for hobby so I bought gauges to monitor my unit and learned what Superheat and subcooling are. I determined that I don't have a leak! So what is it? I have an energy saver cycling box from the power company, I have that taken off, it takes a few weeks for them to do it. but my problem persists! I'm going mad, inject dye to search for leaks? I change filters, etc etc. anything i can. I'm debating draining the unit, perhaps the repair guy put in too much or incompatible oil!I begin to suspect the thermostat, all the internet says it couldn't be the thermostat, no no It could never.. But I say I say you know what let's reset the thing and strip away features. So I did, Reset it, turned off scheduling, wifi, and anything else "smart", got into the special menu and found "adaptive recovery" looked it up and determined this and scheduling were my problems! Because I wanted 72 from 8am to 5pm but the 77 at 11pm. The stupid "smart" algorithm thought that meant I want to be 72 in 8am and for the rest of the day slowly drift to 77 by 11pm and then freeze us half to death at 5am to be 72 again by 8am. If I set my schedule to all 72 degrees it will never leave 72 even on a "hold". I assume because of crap programming that adaptive recovery does not take into account the "hold" or manual input/changes which is bullcrap.I decided to see how badly programmed this algorithm was. I put a schedule on with crazy temperatures like 50F at 8am and 90f at 5am or something. The stupid thing would actually turn the HEAT ON to after 8am so that it be 90F by 11pm even though the cool setting was set to be 50F at that time. what a dumb program. Heating when it should be cooling!I was smart enough to figure this out and disable these features, I won't even use the schedule now Im too afraid too Which is same because I really wanted to let the AC drift off temp at night but its not worth it to trigger the "smart" alogrhtium's stupidity which seems to have the ability to override your manual temperature settings even without being turned on. I see no where to fully disable this "smart" features.I feel bad for anyone that calls HVAC specialists to try to fix these issues and they get talked into the a whole new system because of some programmers' poor programming skills.

I was looking to upgrade my original (non wifi) home thermostat with a wirless version. We bough the home new in 2019 and it only came with a Honeywell TH4110U2005 ProSeries thermostat. I knew I could replace the thermostat but didn't want to have to re-wire and affix a totally different wall plate/wiring plug onto our wall. I was hoping I could find another Honeywell version that might be a direct match for our particular wall plate/wiring setup. I am somewhat of a handyman and did not want to spend the money on using a professional to install a newer wifi version. So I did a little Amazon searching and finally found this Honeywell Home Intelligent T5 (wifi) version. It looked almost identical in the provided pictures. All measurements seemed to match up with what my tapemeasure told me as well. The advertisement did say this new thermostat required a "C wire" in its hook up. I had no clue what a "C wire" was. Apparently if your original wiring/plate doesn't include a C wire an additional wiring kit was needed to make it work. So, after I pulled the old thermostat off its mount, I could see how the wiring plate was configured. The mounting plate looked identical to what was shown in the advertisement for the new thermostat. I could also see a wire spot in the wiring/plate that said "C". There was in fact a wire going to the post labeled as C. Intuitively I was fairly confident that this new thermostat would be directly compatible with the old wiring/plate mount on our wall so I placed the order. After the item arrived I went to work and it took probably 30 minutes to unbox, read (somewhat) the instruction manual, pop the thermostat into the wall mount (it fit perfectly), download the device app, set it up with our home wifi, and then get the cooling/heating parameters all set up like we wanted them. The only thing I forgot to do was flip off the circuit breakers (like instructions said) to the HVAC before I popped out the old thermostat and inserted the new one. But I had shut off the HVAC system using the old thermostat before I pulled it out. Everything worked fine so I don't think anything got messed up as a result. We have since been using this new thermostat for about a week now and I am pleased with its performance, compatibility with the older thermostat setup, and reasonable price. The app on my phone allows me to control everything while I am away from home as well as a geofencing feature. The thermostat is doing everything that was advertised and I expected. I am happy with the purchase.
