Exact replacement for ease if installation, works great. Less expensive here than my contractor could buy it from his supplier.

I HIGHLY RECOMMEND THIS THERMOSTATFirst of all, I want to correct some misinformation from another review. One reviewer indicated that you could not illuminate the backlight without changing the current state of the thermostat. Either that problem has been corrected or never existed. If you press either of the set point up or down buttons, the backlight illuminates and the set point does not change. A second push while the backlight is still on will change the set point. Very convenient. I am delighted with this thermostat.HISTORY OF MY STRUGGLES FINDING A GOOD THERMOSTATEver since replacing my HVAC system nine years ago with a two stage heat and cooling system, I have struggled to find a decent thermostat that does a good job managing the two different stages. It is nearly impossible (even when reading the installation manual) to discern the logic used by the thermostat's algorithm concerning when it will run on first or second stage cooling for example. Furthermore the installation manuals explanation of the setup options don't really explain what the actual hysteresis will be. Some have a “delta temperature” setting where the choices are typically 0.5 or 1.0 or 1.5 deg F. These choices are too granular and don't work for many homes with good installation.In my case, on hot summer days the Braeburn 5390 thermostat that was installed with my system would generally run far too long (usually on high cooling stage) before finally shutting off 25 to 45 minutes later. Then it would remain off for 45 minutes or longer before turning on again. All this with the setup option set for 0.5 deg F, the most “sensitive.” The house was never comfortable.Early in 2024, I tried an Ecobee 3 Lite. See my full review on Ecobee. I bought it because the installation manual indicated it has a setup option to select how many cycles per hour the system should run. I set that option to the most cycles per hour allowed and it still only cycled about once per hour – running 30 min or more each time it called for cooling. It was an improvement in that it did a better job of managing the two cooling stages but still did a poor job of keeping the house in a comfortable range. Due to this, and other worse behaviors you can read about in my review, I only used it a few months this past summer.THIS THERMOSTAT WORKS GREATLate in the 2024 summer cooling season I purchased this Honeywell FocusPro 5220D thermostat. It is perfect! Besides being simple to set up to match your system type, it has a very robust choice of options for controlling the two stages. It has separate options to control how many cycles per hour it should run when running on first or second stage. It also has two separate options for the heating stages. The default for each of these options is 3 cycles per hour but it has many more options. You don't have to guess what hysteresis or “delta-temp” to set it for because it adapts itself to your house. If you have a very well insulated house it will automatically reduce the hysteresis or temperature delta in order to cycle the appropriate number of times per hour. As expected, this means the air conditioner runs less duration and on a lower stage when the outside temperature is lower. It also does a good job of staying in first stage cooling unless absolutely necessary. My old thermostats including the Ecobee insisted on switching to high stage for a few minutes at the end of each cooling cycle when there was no reason to do so.ADDITONAL BENEFITS OVER PREVIOUS THERMOSTATI very happy that this thermostat has battery backup (or battery primary power if your system does not have a common wire run to the thermostat). I am also happy that it does not lock up in a ridiculous “calibrating” cycle for 20 minutes every time the power goes out like the Ecobee, and that it remembers the set point when power goes out. I'm happy not to have to dig three or four levels deep into setup menus just to get it working like the Ecobee – all while standing next to the thermostat since the Ecobee it has not battery. This Honeywell can be set up while sitting in your easy chair prior to installation. It does not need WiFi or internet to operate. The Ecobee behaves very badly and refuses to operate properly without internet connection.

Works like a charm. Level the extended screen as well

Good thermostat. Easy to use

We have a vacation home where we have to turn the Heat on and back off each time we come and go, and my elderly Dad needed something easy to read and easy to use. This one fits the bill perfectly. We set ours up for "HEAT ONLY" since we don't have A/C out there and now under the "System" heading it has: "Heat and Off ". That's it. Just like it should. No extra "Cool" setting that we don't need which only confuses the issue! When it's "Off" the display for the temperature setting disappears. When you turn it to "Heat" the display pops up on the screen again. It's very obvious when it's off and when it's on. There are 4 simple hard buttons on the front, Temp: UP/DN System: HEAT/OFF (in our scenario) and you will never need a manual once you get it installed. It couldn't be more intuitive.The display is very clear and easy to read even from a distance and the Amber Back Lighting is really nice looking and makes it easy to read in the dark. The Font size for the lower display on this one is 13 point versus 11 point on the models with the smaller screen. In other words, considerably larger and easier to read. The "Inside" and "Temperature" settings are huge and very easy to see even for me without my reading glasses...It's really easy to install and I was able to use this same model for both our 80% Furnace downstairs and the 90%+, 2-Stage Furnace upstairs. That way we can have the same one up and down. Very convenient and very versatile. It fits most other types of Furnaces too. Including ones with A/C and Heat Pumps. Auto Changeover is a nice feature that I use here at home (also a Honeywell) and love. About the only thing that makes it not perfect is that there is no way to keep the backlight on all the time like you can on the top of the line models. I have to say though, once I got used to not having it, it wasn't an issue. I'd recommend this Thermostat to anyone looking for something simple to operate with an easy to read, large display.
