Frequently asked question

Does this have a battery backup?

It has a battery for memory back up, but it runs off the C wire. Be sure your thermostat setup has a C wire.

Does this thermostat have a setting so that it drops two degrees instead of one degree so the furnace doesn't run as often?

Here's a link to the manual for setting up the more advanced functions: find what you're looking for there.

Can you program the fan circulating feature in the 7-day programming? I only would want that feature at night.

you can choice the fan setting (on , auto & circulate) for each part of the day wake. leave. return. and. sleep

I see users can use an iPhone app to operate their thermostat....would an iPad app work the same way? Thanks.

Yes, we use an iPad app to control our thermostats. Works great. Quicker than the web site. We have no iPhones.

    Great Thermostat

    We have a WIFI thermostat in two separate locations, and it’s never certain when we will be in which location. So WIFI is really nice, to match temperature to changing schedule. It’s also important to remotely check that the HVAC is working correctly. Honeywell is pretty reliable. We have waited for many years for WIFI thermostats.
    This is our second 8000 series thermostat (1st WIFI), both touchscreen. For whatever reason, the screen on the WIFI version must be read head-on in daylight. The non-WIFI version could be read from any angle in daylight. The non-WIFI version had 3 solid Ni-MH batteries. The WIFI version has a single little flat battery (Hg?). So I am still waiting to see how it retains setting in a power outage. Otherwise, I’d give it a solid 5 stars.
    The hookups were almost identical to our earlier non-WIFI 8000 series, so I was able to make the switch without help from a professional, and Amazon didn’t seem to care that they were selling a professional version to a DIY – bless them. You can’t just buy this thing at Lowes. Lowes only sells DIY, and we have an outdoor temperature sensor on our heat pump. For a DIY starting from scratch, with a complex HVAC, this might be a bit of a steep climb. And if you don’t have an outside temperature sensor, and you don’t care about compressor lockout, you are better off with the DIY version.
    We were recently away from internet for a week, when the WIFI server did a reset. The thermostat continued to do its job correctly, but Honeywell sent us 24 error warning emails each day for a week. The WIFI feature is only as good as the WIFI. That’s one advantage to Honeywell’s decision to get between you and your thermostat. They will definitely warn you, again and again and again, when something goes wrong with your WIFI.

    Great thermostat, bad customer support.

    I purchased this thermostat a few months ago and just got it hooked up in the new house. It is super easy to program and I really like all the options. The two main reasons i bought it is because of the of the outside sensor option and the wifi. We live up in the mountains and I want to be able to view both temps, especially when we are away for holidays to make sure our heat is still working so we don’t come home to busted pipes. Also so we can kick the heat up before we arri arrive. It connects to wifi very easy and changing the schedule is a breeze. When I hooked up the outside temp sensor it didn’t come on automatically and it didn’t give me the option(340) in the function menu. It skipped from 330 to 500. So I read my manual again, searched online and came up with nothing. I then called customer service, that was a complete waste of time. The lady was nice, but all she could help me do was to set the schedule up. I asked for a tech support phone numer and she said it is for licensed contractors only, wouldn’t give it to me. She said because this is a contractor model only I needed to call a local service shop and have them come out and program it for me. I told her I live up in the mountains and that would be at least $100 for the service call due to distance. Also i didn’t need to pay someone to hit a few buttons to unlock the rest of the functions. She still wouldn’t help me so I said thank you for your time and hung up. Then I hit up YouTube and watched a guy program one, well to get to the rest of the functions you hold down both buttons on each side of the middle one. So the main functions are accessed by holding the middle button like the directions say. The rest are accessed by holding both buttons on either side of the middle one. Glad i didn’t pay someone to come show me that. Hope this keeps someone else from calling customer support or paying a service tech.

    14 Thermostats in 6 building locations and THRILLED!

    I couldn’t be happier with the 14 Honeywell TH8320WF1029 thermostats! They have saved us approx. $3,000 in heating and cooling over the past 12 months.
    The building is an 1895 restored opera house. We are a non-profit with limited budget, and none to waste. Through the Honeywell TotalConnect portal I created 6 locations with anywhere from 1 to 6 thermostats in each. I’ve set up schedules to control floors where lessons are held, as well as a schedule for the Box Office to kick on at the start of the day and kick off at the end. The auditorium, banquet hall and ballroom, etc. are left at a constant 60° in the winter and 85° in the summer until we need to use the room and are turned on in time to heat/cool the area(s) by the time patrons arrive.
    One huge advantage of these thermostats over the non-wi-fi Honeywell thermostats these replaced is that we can turn the heat/cooling on exactly when we need so as to heat the auditorium by showtime. Previously they were turned on sometimes 2 to 3 days early as no one would be back in the theatre prior to the show. This alone is a major improvement and has been a great money saver. And on top of that, now no one has to trudge up to the balcony to physically set the thermostats in that area. (And no one ‘forgets’ to turn them off!)
    This winter has been brutal and we’ve had to postpone 2 shows due to weather emergencies. Being able to turn off the heat remotely is a godsend. Neither the exec. director or I could have gotten to the building to turn the heat off. And each day it’s heated is hundreds of dollars.
    Here are just a few more features that were very important to us:
    • Able to ‘lockout’ the keypad so unauthorized people can’t change system to heat from cool and vice versa. (Patrons and renters would actually turn on AC in the winter if they got warm from working, instead of turning the heat down!)
    • Able to set a minimum and maximum temperature. In heat mode, the keypad won’t allow heat to go above 74°, in cool it can’t go below 72°. (This prevents patrons and renters from cranking the heat up to 85° because they’re ‘chilled’.)
    • Able to set up schedules for work and lesson areas.
    • Able to monitor the building temperatures. With 14 units it’s easier to see when something needs to be serviced before it will be needed.
    • Able to set up the TotalConnect app in a logical way to control each floor and area separately and easily.
    Installation: We are in an area where technology is, shall we say, in its infancy, as far as contractors go. It’s understandable since only a few businesses in town have fiber optics available. Some people have cable internet, but most have to make do with satellite internet. That being said, our HVAC man installed the thermostats, however I am the person who set them up.
    The service manuals are ‘in the box’ so once I got started on programming them, it was simple. Just a little time consuming. 4 of the thermostats have remote sensors (to the stage) and that didn’t add any problems.
    The *only* problem I had was connecting 2 of the units to wi-fi. I kept getting an error, so called Honeywell. They couldn’t have been nicer or more helpful! (And yes, I bought these on Amazon.) The gentleman explained to me how to reset the wi-fi to factory and walked me through connecting.
    On occasion we’ll lose contact (power outage, server goes down) and I’ve set the notifications to alert us after 1 hour. It sends just one email alert and that’s it. (Prior to finding that setting, we got lots and lots of notifications. Explore the TotalConnect online, not through the app, to find settings.)
    It’s been a 18 months since I bought the first wi-fi Honeywell Thermostat and installed in the box office. It saved us $100 on our first electric bill, so we approached the board about changing all in the building. The rest were installed a year ago. They have paid for themselves over and over just so far.
    I highly recommend these for other small businesses!
    UPDATE: Still thrilled! A note about programming… Some of our units use heat pumps, some don’t. This winter one heat pump went out and the unit needed to be set to backup heating. I, not being an HVAC person, wasn’t sure which options to choose in setup so had left it at default (none). Our HVAC guy went to the theatre and I was able to walk him through on the phone how to access the programming to change it to what was required for backup heat. The programming is very simple — if you know what to select!
    I’m also adding a photo of the phone app to show just how easy it is to keep track of many thermostats in a large facility.
