Honeywell TH6210U2001 2HT/1CL PROG 24V T6 STAT 2HT/1CL PROG 24V T6 STAT

Fixed our problem! Came really quick!!

AC company installed a smart thermostat when they installed my new ac... for several years my ac would not work well. Id lower temp and thermostat would go up. It was quite frustrating and costly (in my electric bill) so my new ac guys suggested changing thermostat temperature control and I chose this (recommended by them) ..... things have been wonderful since. easy to install, easy to read, temperature control is great and although you can't schedule changes in your temperature (atleast I have not been able to figure out) it is fine with me to change it on my own.

It works well

I cant comment on any complicated heating/cooling setups but works great in our late 80's built home with a single stage R22 A/C and central forced heat (gas). The programming options are plentiful but whats great is you can configure this thing to hide away all the complicated settings you dont need. I was able to configure the thermostat to only allow manual A/C operation which is perfect for the less technologically inclined. Looks good, installs easily, and has the option to combine batteries and a C wire for reliable operation that can retain settings after a power surge. Definitely recommend

We had to replace an HVAC unit that heats a room that had been converted from a garage. So the heating of this room is separate from the rest of the house. At this point, the room contains our pet parrots. Programming isn't necessary, since this room is kept at a consistent temperature, and we wanted it only for heating since our new HVAC unit doesn't supply air conditioning. In looking for a new thermostat, I have to admit it was quite daunting as so may offered options we really didn't need. This unit was cost effective, and the programming can be turned off if you don't need it. Without the programming, I can easily set the target temperature for heating as needed. These things really don't need to be complicated if you don't need them to be. For us, this thermostat is a huge improvement over what we had. The previous thermostat had a lever that adjusted the temperature as you would a wafer heater - it was all guesswork. With this thermostat, I can set an actual temperature digitally. I'm sure some of you are laughing your butts off at how archaic our heating system was, but then there are likely others with a similar situation. Sometimes all that is needed is a reliable thermostat to set heating, and/or air conditioning, temperatures accurately. Everyone does not necessarily need programming functions. What I like about this thermostat is that it can be programmed if you have a need for it, but you can also keep it simple to just set a consistent temperature without the programming. I also like the display is large enough to see without glasses, and the preferred temperature is easy to set. The display is dimmed until you press a button - then it lights up. Sometimes lots of options are nice, but sometimes, it's nice to be able to keep things simple. UPDATE 08/22/22: Even though we use this thermostat only for heating, I decided it might be a good idea to program it so the temperature was kept a bit lower at night than in the day. You have the option of using 4 settings, but I wanted only 2, one temperature for day and one for night. For only 2 settings, you can deactivate 2 of them. I also wanted the temperature setting to be the same every day although you do have the option of setting up different temperature settings for weekends and week days. I found the settings to be very similar to the timers I use for lighting the plants in my basement garden. So, I didn't have a hard time at all understanding how to program this unit. Considering the current costs of energy, I am hoping programming of this unit will help us to save costs for heating this room. We are also considering getting another unit like this to control the heating and air conditioning of our house since our electric and gas costs have become so expensive. I hope this review was helpful for you, and I will update my review if my opinion changes.

Great once you get everything set up- but did invite panic… wiring is very straightforward for anyone with basic electrical skills, but the programming manual is lacking- any code above 365 to 1450+ is not listed in the manual but is needed to properly setup the system. The factory ac cycle was 5+ per hour (not good for the life of the ac unit!) and was set at 9 per hour for the heater! Yikes! Small price to pay for a “smart but dumb” unit, overall good so far! FYI, after programming, it still took 20 minutes to turn on the air conditioning. That’s what gave me panic. I manually turned on the heat/ac and blower to verify the controller was working properly, and they did; and it still took 20 minutes to come on the first time by itself with the temp set at 72 and it was 78 inside/90 outside. No problems since

Return window closed on the 7th. Unit failed on the 14th. This is the third unit to go bad and I am switching brands for sure. The first one came with the house when I moved in. The second one, I bought here, on Amazon, when the first one failed. When the second one failed, only certain buttons would no longer work. After a horrible interaction with customer service, trying to get a warrantee replacement, and a faulty meter reading on my part... (unit needs 24 volts, which it was getting; but my meter was only showing minimal voltage for some reason. Customer service said the unit failure was my fault and therefore voided the warrantee. A couple weeks later, my AC tech friend was addressing other issues and threw his meter on the thermostat leads for me. His meter read optimal voltage while mine still read inadequate. Now, I need a new meter AND a new thermostat; meaning the thermostat was getting the correct voltage all along and my warrantee should be valid) ...I just decided to order another one of these because it was the easiest solution. Time is money and all. I did not want to replace the wall "plate" to which the thermostat connects, so, like a fool, I stuck with the same brand and model again. As far as I'm concerned, Honeywell still owes me a warrantee replacement which I will never see. The next unit will not be a Honeywell, unless it's a free Honeywell.

I have the T6 Wifi version of this thermostat and it died a couple of months ago, 6 months out of the 5 year warranty. The HVAC guy had this non - Wifi version on his truck. He plugged it in and it worked instantly. It only needed minor scheduling setup that anyone can do. This non-Wifi thermostat was a loaner from the HVAC company but it gave me heat instantly. When the Wifi version arrived, the HVAC tech came back and it took him almost 90 minutes to get the Wifi T6 to work. He was exasperated. We almost left the non-Wifi version on the wall but I need the Wifi function. The take home message for me was to order this non-Wifi version as “insurance”. If my T6 Wifi model ever dies again, I can plug this non Wifi version into the same wall plate for the Wifi version and it will work immediately. BTW, both this T6 and the Wifi T6 thermostats brag about a 5 year warranty. BUT, that warranty is void if a homeowner installs either of the T6 thermostats themselves. See note on the box of the photo of this thermostat still in the box. Hope that helps!

Great product. Works well and was easy to install. A great alternative to other 'smart' thermostats (like Nest) that suffer from software updates and resetting often to defaults. This one is easy to use and just works great. No control system battling with the smarts that are built into my high efficiency furnace!

Tienen excelente diseño moderno

Worked for us , we replaced an older one for a propane heater.

Nice thermostat with heat, cold and an air circulation feature.

Has been installed for many months now and have had no issues. I don't find it intimidating to use and that is saying something! We installed it after getting a heat pump so we could control when it would(if necessary)need to switch to the propane. Works well with our air exchange system too.
