Impossible to program. Tried to lower the temperature of my own home, and it decided to make it even warmer. You had one job: make my house certain temperatures when I tell you. It wants to know what it should be in a week. Can we cross that bridge in a week please?

Avoid at all costs
We inherited this thermostat when we bought our house. It is clumsy to program and difficult to override.

Worst Thermostat Ever
I’ve had a 30 year old Honeywell thermostats and have never had a problem. Bought the RTH221B. This one is the worst piece of plastic and wires ever put together. I programmed it to heat to 68°, but it pushes the heat up to 71°-72°. I’ve lowered the setting to 67° and it’s still registering 71°. I contacted customer service and they claim there’s nothing wrong. Really! This was a simple two wire installation so there’s no error in that. Additionally, when trying to install the batteries the whole thing fell apart and took forever to get it back together. Luckily this happened before it was a fixed to the wall, so laying it on a table was a bit helpful. Now I’m wondering what will happen when the batteries die; will I have pieces all over the floor.

works fine for a week, and then...
Get it installed. works fine and then just stops functioning. Remove the batteries, put new ones, nothing. Reset panel. The thing is dead.

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).

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.
