HoneywellTH5220D1029 Focuspro 5000 Non-Programmable 2 Heat and 2 Cooling Thermostat, Large Screen

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.

Why did you pick this product vs others?:It's simple and it works.

Replaced my thermostat myself. Works as intended

exactly what I had and wanted. Very good price got in a couple of days so was not out of air conditioningvery long.

This was purchased after a lot of research & finding best price & return agreements on Amazon. I have a 2 stage heat 1 stage cool system for which is hard to locate a non programmable thermostat that actually utilizes the 2 stage heat. I had a professional put it in who was also performing my yearly maintenance check. I had twice found my 7 year old programmable thermostat continuing to run way above the highest set numbers. Did not want another programmable one. My local gas company does not recommend them either. I just lower the heat now if I'm leaving for several hours. I can just set the air at 80 & leave it for the summer. The back light does not come on unless you push the temp buttons & stays at the same number until the second push. However, the system button doesn't cause the light to come on - it just immediately changes which system is displayed so be careful to leave it alone. Very simple & easy to use. My winter gas bill says I saved over last year & my bill came with a reward bonus for this.I'm adding this after having the thermostat for a few months: First of all I still love this thermostat, but noticed another reviewer mentions the thermostat registers up to 3 degrees off. This appears to me to be true of mine also. However, since my other thermostats were installed by people who asked if I wanted it adjusted to exact temperature, I believe it is up to the installer (see pages 6-8 of installation manual, & page 3 of the operating manual) to mention the adjustable temperature most come with. They are set by the factory & like ovens etc. can be adjusted (usually up to + or - 3 degrees) at installation. It took a few days for me to recognize mine was registering heat lower than set & then since the AC has been on it is also registering lower than the actual temperature. I just set mine accordingly (for me that means up 2 degrees from 66 to 68 for winter & up from 80 to 81 for summer). I'm still very happy with this thermostat & coming out way ahead on my bills over the programmable thermostat.

Does not read correct inside. I wanted to let it get the to the correct inside temp before booking it up but is was 3 degrees higher after sitting on my counter for 4 hours. I set it directly above my downstairs thermostat that I know is accurate and also a separate thermometer, they both read correctly and this one does not. Honeywell customer service is absolutely awful as well. I will be returning it.

Works perfect as described.
