Rated 3 out of 5 by W Truong from Not so great thermostat |I installed model RTH 2300 on Oct 2019. It works fine until Jun 2021. The display blank-out. I replaced with 2 new batrery, it works again for one day, then blank again. This time, no matter what battery put in, no action at all. I call the tech support in Honeywell. The technician is very friendly, helping me to test the thermostat step by step, using the "ViewSupport" app to look at the wiring of my installation, then told me the thermostat is dead (and out of warranty ready), based on the wiring he saw from the cell phone, he recommend me to install another model RTH2410. I did as she told, and the new thermostat works right away. The product did not last long but the service is great. So I gave 3 stars.

Rated 5 out of 5 by ComfyCool 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 1 out of 5 by Kalom from Garbage Honeywell should actually have to pay us to use this 1980s low quality piece of ! It should not be classified as a thermostat it should be listed as a "programmer"!! That is all it ever tries to start but oddly enough it never actually does!?

Rated 1 out of 5 by ron222 from Difficult installation My older Honeywell thermostat had a C terminal clearly marked and was being used. This new unit doesn't have a C terminal and nothing is mentioned in any of the manuals or installations guides. I don't understand why?

Rated 4 out of 5 by Outafucs2giv from Does the job I purchased the RTH2300 B a few years ago and have not had a single problem with it. Easy install, it is small, has clean lines and, for all of the functions, seems minimalistic. The One and Only problem I have is that there isn't a lock function. My oldest daughter can finally reach the buttons and turned the heat up to 86°F before we left the house for the day. She wanted the house to be warm when we returned from sledding. Too bad we went sledding 2 hours away and didn't return for 12 hours. You get your money's worth with this product. It wasn't the least expensive 5/2 programmable thermostat but it looked better, had more functions and, most important of all, it does what it's supposed to do. My only critique, Add A Lock Function. Heck, even my TV remote and toaster have locking capabilities.

Rated 2 out of 5 by Colonel 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.
