Great Thermostat
June 1, 2017
I had some initial troubles installing the unit but after find the actual power feed down on the furnace board and tapping into it, the unit powered on no problem. Setup was easy and it's proven quite reliable. Managing the HVAC from my smart phone is nice. I rarely use the actual unit but it looks a lot better than the ugly LCD unit I had on there.

I wish I could set the Heat/Cold temperature ranges to a tighter difference. Currently it forces a 3* separation and in my house, that can make a difference in comfort. However, for the cost, I recommend this vs the competitors.

Also, honewell is good and notifying you of planned maintenance if the app link to their servers will be down. Other than that, I've had zero connectivity issues.
Nice Thermostat! Glad I purchased it.
February 14, 2017
Great Thermostat! I read a lot of the reviews prior to purchasing and after receiving mine and installing it myself I dont see what the 3 star and below reviews are about. the unit was not difficult to install, the back-plate / mounting plate seem to be fine and I had no issues with the wiring. The only thing I can figure is that the other people with the lower reviews probably had no business installing a thermostat themselves or probably anything else for that matter. It does take some dexterity to wire the unit. The wires and slots for the wires are small. But other than that..Read the instruction, watch a video or two that Honeywell has or on YouTube and put it on the wall. No big deal. I like the thermostat I purchased and it does appear to work much better then the factory Carrier thermostat I replaced it with. The HVAC heat pump unit actually cycles properly now and the temperature in the house seems to be much more consistent. Two Thumbs Up!
Nest thermostat vs. this Honeywell thermostat
April 7, 2016
I'm giving a head-to-head review. I've had both a Nest 3rd Generation thermostat and this Honeywell touchscreen thermostat. I like both a lot, actually. It depends on what you're looking for in terms of deciding which is better for you specifically.

I love the simplicity of the Honeywell's touchscreen. And I like that it tells you the outside temps and humidity, the date, and time all on the home-screen, all at once. Nests have much less info on the screen and you need to turn the dial and find everything, like weather, etc. On the Honeywell, to navigate to settings and schedules, there are touchscreen tabs at the top of the screen. Pretty intuitive.

Wiring:
The Honeywell absolutely requires a "C" wire to work. If you don't have one, you will need to run one for the Honeywell for it to work. I originally did not have one, but I had one added for $100 by an electrician. If you don't want to go through the expense or hassle, you may want to go for the Nest instead, because while the system works best with a C wire, it can work without one. But it depends on how much power it can pull from the other wires. Not having a C wire can make its Wi-Fi connectivity spotty/intermittent. And that means sometimes you can't interact with it via the mobile App and delays in it knowing what the external weather is.

Apps:
Nest has its merits, for sure, like their App that gives a lot of insights as to how you're doing with efficiency (like showing that for the past week, Monday, the heater only ran for 15 minutes; and Tuesday, it didn't come on at all... that kind of thing). I will say, however, Honeywell and Nest keep improving their Apps continuously, so as soon as I comment on App features, they change and have new functions... so that's a positive for both products. Who can be upset with constant improvements?

Aesthetics:
Both the Honeywell and Nest are very slick/modern looking. With this Honeywell, having the ability to choose your screen color to work with your décor or style is something that's pretty neat. Or you can change it up when you're bored. The Nest, however, does not have a function to change its color. It is always black. On the other hand, the Nest itself with its circular face is just pretty cool looking on its own. I'll leave you to decide what is more pleasing, as it's a matter of opinion.

Some notes about programming your schedule:
Nests, are all about "learning" about you. So, in default/factory setting mode they are set in "auto" schedule program mode, which means you go about your daily routines and "train" it, so it learns your preferred home temps and schedule. If you're letting it "learn you", it goes something like this... You to wake up, change the temp, leave the house and adjust the temp before doing so, come home and ... You get where I'm going. Finally, after a few days of that, it pretty much understands your patterns (unless you're really unpredictable/erratic). That learning feature can be awesome for some, since some folks want to let it do the work. But some people are more control freaks (like myself) and want to tell it what temps at what times to come on and off from the get-go. So, if you find the learning feature takes too long to learn your schedule, simply read the directions and turn off the auto learn function, and then program your schedule to however you want. The Honeywell does not learn and has you set your desired temps and schedule from the first moment you install it by default. But it gives you quick-set recommendations, which make setting up the schedule super-fast.

Bottom line:
Both are absolutely great thermostats. I love them both for different reasons. Maybe the biggest difference for some would be the "C" wire requirement for Honeywell (if you don't have a C wire in your wall already and if you don't want to have to have that wire added).

I always read reviews before purchasing and find some quite helpful, so I hope you find this review helpful!
Nice, cool (haha) thermostat!
October 22, 2015
This thing is glorious. It has a bright, easily readable screen that is crisp and clear, and it looks nice on my wall. Installation was (mostly) a snap, and took less than 20 minutes to get it from Amazon box to on my wall.

I bought this thermostat for four reasons: 1) It seemed to have more functionality than the NEST, 2) It was about $100 less than the nest, 3) it works with Wink, and 4) I can use set it up for monitoring by my electric company (CPS in SATX), and I'll get ~$120 in rebates, which lowered the cost to purchase to ~$40!

A few nuggets of advice that you might find handy: check what sort of heat source you have in your house, whether it's forced air or a heat pump. If you wired it correctly (after obsessively checking five or fifteen times) and it's still blowing hot air when your AC is nominally on, then you have that particular setting configured incorrectly. Go back and change "forced air" to "heat pump," or vice versa. Also, when you first turn on the unit, there is a five-minute lockdown to prevent the system from blowing itself out. Just wait it out, and go from there. (These things are printed in the instruction manual, but... yeah, I stopped reading once I saw where the wires were supposed to go, so I missed this. Be smarter than I was, and read at least the quick-start guide all the way through.)
Easy For Anyone To Use, Anywhere
October 21, 2015
I purchased this thermostat for my father. He isn't a big tech fan so I was worried he wouldn't be able to use it. He loves it! It is extremely easy for him to use. He even purchased a second one for the upstairs unit.
Normally I would install something like this myself and be able to give details, but we already had a professional over installing a new air conditioning/heating unit and he offered to install it for no extra charge. I spied on the installation a little and it just looked like a few wires.
Once it has power, there is an easy to follow guide to set all your defaults, wifi and even colors.
Honeywell has an app so you can control this thermostat from your phone when you are away from your home or if you just don't want to get out of bed at night to adjust it. Setting that up was pretty easy. You create an account on Honeywell's website. It will ask you for your thermostats MAC address which you can get right from the thermostat screen. Once done, download the app to your phone (iPhone in this case), sign in and all your controls and current temperature are right there.
Overall, a great product that will help you reduce energy costs.

I love this controller so much
September 4, 2017
I love this controller so much, thanks to honeywell! Seriously, unless you are looking for the futuristic look, why spend $300 to buy a nest? My home has two AC system, and I have replaced both thermostat with this guy! Here is why I like it:1) Super friendly to people who travel. App is easy to use and interface is very intuitive. You never have to worry that your home gets too hard/cold, or your utility bill exploded in extreme weather2) For landlords, you can control home temperature without having your tenant fudging with the temperatures while you are away3) You can set temperature schedule to make home environment more comfortable.Note: You do need to muddle through the installation process. We ended up tweaking a bit on my AC's circuit board a bit.... But overall it's well worth the investment!
Honeywell WI-Fi installed (this one) in 30 minutes. Get one and figure out the C wire and you are all set!
June 26, 2017
This is my 2nd purchase of this wi-fi thermostat and I'm very pleased with the results so far. The first one was purchased about 2 years ago and was the typical $99 but the one installed today only set me back $79 BUT I was surprised that for the first time in probably 15 years of using Amazon, I was charged sales tax. That ride was bound to come to a stop sooner or later. Oh well, still can't beat the great prices and free shipping on most items and I'll continue to use Amazon as much as possible.Anyway, the reason you're reading this is to gain some clue as to what/how to get that dreaded "C" wire that is required to operate this device in wi-fi mode. I realize all systems/set ups are different but in my case, I did have at least 1 or 2 spare wires on the existing thermostat wire and was ultimately able to connect that extra wire to a 24V continuous connection within the air handler or heating unit, if you prefer. I'll admit, the one I installed a couple years ago was a real test of my wits and my will. Conservatively, if I count the time researching the internet and climbing in and out a dozen times to where the gas furnace resides, it took me about 4-5 hours...I know, ouch, but I've found the convenience of adjusting the thermostat from anywhere in the world to be well worth it, hence the 2nd purchase for our downstairs unit that was installed today. Redemption was had when I met the mailman today and had my new unit mounted, wired and working in about 30-35 minutes, start to finish! What was my secret? The set up was very closely matched to the work I did a couple years ago and with just a little luck on my side, I connected the extra C wire to the correct wire nut right off the bat. This unit is an old school hydronic system (uses hot water to provide the heat for the house) matched to a conventional AC condensing outdoor unit so I wasn't so sure but again, all systems go in about 30 minutes.In a nutshell, you have to connect that C wire, assuming you have a spare wire already in your thermo wire, to 24v continuous electrical supply in order to power and run this thermostat. I'm sure electricians and AC guys may find this amusing and could do something like this blindfolded but for a commoner (there's that C reference again), this was a major score to get this one running quickly. Love it!
Simple to install and simple to use WiFi Thermostat. Works with Alexa!!!
February 24, 2017
For $84 and free 2 day shipping, this is the best WiFi thermostat for the price. I looked at all the expensive options, but I eventually chose this based on simplicity and the fact that you can do pretty much everything from the thermostat itself. I had a honeywell thermostat that looked exactly the same, except this one has one extra button. That one only gave me the ability for weekend and weekday schedule. With this thermostat, I can have a different program for each day. Just that alone is a major upgrade.The WiFi capabilities are much more than what I could ask for. Only gripe I have about the WiFi is that it is not dual band and only works with 2.4ghz networks. The app is simple to use and offers a few more benefits than using the thermostat on the wall. With the app, you can group days you want to have the same schedule and set them all at once. You can also set a hold for a specified amount of time. If you change the temperature it will say hold until your next set point. Then you can change that time to whatever you want. Then at the end of the hold it will automatically return to the schedule. It also works with Alexa once you have enabled the Honeywell Skill.Here are things that I don't like, but are not enough to take a star away.-There is no battery backup and it requires a C Wire. But since it's on WiFi, it will automatically set itself if you disconnect or if there is a power outage.-There are no reminders to tell you that you need to change your filter.-If you manually change the temperature, it will show "hold until XX:XX" on the screen instead of the actual time. They could have programmed it to also show the current time at the top corner or something.All in all, it is a GREAT thermostat. The WiFi capabilities are nice, and if you forget about the WiFi or the WiFi stops working, it's still a GREAT thermostat. If you don't need all the fancy features of the nest or ecobee, then this is the thermostat for you. I just want to be able to change my temperature if my schedule randomly changes, and this allows me to do that. I am more than satisfied.
I am amazed. The setup was simple
December 14, 2016
I have had my WiFi thermostat online now for about two weeks. I am amazed. The setup was simple. The app for my phone is very easy to access and use. I live in South Dakota where it gets very cold in the winter - it is 2 below actual as I write this - and very hot in the summer 112 last July. We travel a bit and it is such a relief to put the system on permanent hold while we are away and as we return home kick the system back on and have a comfortable house to come home to. I am traveling 230 miles to home in the morning, when I am about an hour out I will release the hold and by the time I get home, the house will be right at 70 degrees. It is currently holding at 48 degrees.Of course I have not had the system long and if it fails or begins acting goofy, I will update this review. As of now, I would give it 6 stars if I could.DakotaHoneywell RTH6580WF Wi-Fi 7-Day Programmable Thermostat
Great Funtionality for great price
November 8, 2016
I absolutely love this brand and this model of Wi-Fi thermostat. I have purchased 5 of this exact model off of Amazon and absolutely cannot be more pleased with the product, the price and how it functions. Number one the price for a Wi-Fi thermostat is normally much higher. I purchased these for around $85 and yes that should be a concern when most Wi-Fi thermostats are twice that. I think the biggest difference is that this model does not have a fancy screen with all kinds of colors and digital eye pleasing features. However not knowing in advance I thought this would be a problem. It is not because with Wi-Fi thermostats you will never stand in front of that thermostat again. Once you install it you will use your iPhone or other wireless device almost 100% of the time to program and adjust the temperature. I have several businesses with these Wi-Fi thermostats and one in my home. It is one simple app on my iPhone that I open and can quickly monitor, adjust and if needed make program changes to the thermostats. The functionality is wonderful, the ability to program and making temperature changes is so easy. I will definitely buy this again when needed and I highly recommend the Honeywell because number one the price is some competitive and number to the functionality is amazing. I did purchase a different brand and the install and functionality was much more complicated and just not worth the fun of having a different brand. So when needed I went back to the Honeywell.
Great cheaper alternative to nest
September 19, 2016
This may not do as much as a nest, but it does what matters. It is a programmable thermostat that you can control remotely.As everyone says this requires a c wire. Mine did not have the wire and the existing wire was old and wearing out. Great thing is that the wire for my furnace is a simple run and replacing it was quick and easy. I do have some hobbyist experience with low voltage wiring so I was able to hook the new furnace wire up easily. Of course all situations will probably be different. I understand there is a workaround if you do not have a c wire, there is a drawback but it was not a major one. I do not remember the drawback.After it was installed all I needed was a smart phone or tablet to connect the thermostat to my WiFi. There was an update where the thermostat had to reboot but that is to be expected and welcomed with things like these. During the reboot the furnace unit shut off but only for a minute.TL;DR great WiFi thermostat, just check that you have a c wire on your existing thermostat or feel comfortable with wiring for a fix or workaround.

Works perfectly with Alexa
October 1, 2017
I had an old Honeywell thermostat on this house I purchased last year. It was programmable, but was a pain in the neck to set up. So after I got my Amazon Alexa, I checked out the Amazon website for a reasonable priced thermostat that would work with an Echo. This Honeywell caught my eye, so I read the reviews and decided on this one. Since someone mentioned in their review that the warranty would be compromised if it wasn't installed professionally, I paid my H/C guy the $60 that he wanted to install this when he came for my yearly system checkup.It is a really nice thermostat. It gives your local weather conditions, temps, humidity ( inside and out) and time. You can change the color to suit your taste. Not only does it work with Alexa--it also works via your downloaded phone app. Yes, if you unexpectedly discover that you'll be gone most of the day, you can change the settings through your phone app. Convenient!The only reason I dock a star in the rating is because for some reason, in the middle of the night, the screen gets light enough to act as a nightlite. I don't know why, but it is a little irritating. Other than that, operation has been flawless for over 6 months now.
Not so Smart
January 21, 2017
Looks good, easy install even if you do not have the proper "C" wire but the "smart" recovery mode never really learned to time the furnace to reach the scheduled temperature. In fairness, our weather and the resulting ambient temperature has been very volatile this winter. But furnace would frequently fire to early, sometimes by over an hour, and the temperature would exceed the scheduled temperature both in time and heat by a considerable margin. We finally resorted to turning off the "smart response mode" and just use the thermostat the old fashion way. At least we have wifi access (which we will probably never use) and it displays the outdoor temperature with an additional component. I was also disappointed that it does not integrate with our second furnace system using Honeywell's zoned wifi system other than through the Honeywell server portal. I had anticipated using our Honeywell remote thermostat to control and monitor both furnaces and their zones. In summary, the stat could be smarter and more integrated with the current Honeywell products.
Great product worth the money
July 6, 2016
This was a great buy. It cost 200+ in the store so the price is great. I picked this because I wanted wifi, app enabled thermostat. I did NOT want the stupid AI Nest crap. no thanks. You can get cheaper wifi but I paid extra for the nicer looking design and the weather integration. It was very simple to install and connect to my router. I reduced it 1 star for the following 3 reasons.1. The tabs on the wire connectors were flimsy and 1 broke off exposing one of my wires during install. In reading the manual afterwards it does specify to ensure your wires are perfectly straight before inserting them so there is a warning. Be sure to follow this and you will avoid my mistake. It did not impact operation at all just annoying.2. When it disconnected from my router 1 time in 3 months of owing it, it did not recover gracefully. I had to delete the connection and make a new router connection.3. there is a slight delay in the touch screen responsiveness. Enough to be annoying but not a gam changer since I use my phone mostly.Overall its a great product and I will be buying a second one for my downstairs. I wanted to test this one before buying both. I would reccomend this over the more $$ Nest anyday.
Great T-Stat; Installation a little tricky.
June 13, 2016
Love the T-stat, it connects easily, and I didn't need to do any fancy port forwarding etc for my router to get it to work. It controls it reliably, or at least it has for the past 2 days.I took off a star for 2 issues with installation.First, the snap-in connectors I'm not a fan of, personally. Being on both sides (a left and a right) inserting the wires definitely needs some needle nose pliers. I prefer the screw in terminals. Having to relocation this thermostat I fear those small snap in connectors will wear out. Hopefully any replacements would be cheap (if ever needed) since it's just a back plate. Also, be sure to cut back your wires if your t-stat wire doesn't have room to move into the wall. Mine was stapled tight on the other side of the drywall, and if you have the smallest amount of excess wire, the tstat will not snap on. I had to re-do the installation after cutting an inch off of each wire.The 2nd issue I have with the installation is that they don't describe the wires very well, just the colors. One connection is O/B-W, and if you have an orange, a white and a blue, this was confusing. I wish they would say "the O/B/W is for the reversing valve". Installers will know this by heart, but going from a Bryant tstat to this, I wanted to make sure I got it right, and I had to do my own research. For those going from Bryant, my experience was that O/Orange goes to O/B-W and the W/White goes to W2 (emergency heat).I would buy it again, and plan on buying more for a vacation property I have.FWIW, While on vacation this week, I was able to remotely program it to stay at 80 degrees cool until 3am and then go down to 75 until 6am, then back to 80. I did this rather than the vacation mode because it allows my system to "bank" the cooler air when it's cooler outside and run at peak efficiency, hopefully reducing the amount of run time during the hottest part of the day. Since I can put the system back to 74 when driving home, the "vacation mode" doesn't appeal to me.Note to Honeywell, I wish the vacation mode supported that economy method I used (bumping down at 3am for 2 hours).
For Water Furnace geothermal users: get someone competent to install.
March 13, 2016
The bottom line: the thermostat works perfectly well, but installation can be tricky, at least for an older Water Furnace geo-thermal system. Water Furnace has an internet connected system for its newer units, but nothing that can run an older unit. I had read of horror stories with trying to use Nest on geo-thermal systems and this thermostat was recommended by a geo-thermal installer/consultant. "You can do the wiring yourself," he said. Wrong: one look at the way the Water Furnace displays its wiring scheme was enough to convince me to hire a professional.And here's the lesson: I hired the same company that had installed the geo-thermal system for the previous owner 13 years earlier (the consultant was based much further away). Truthfully, I was uneasy when I asked the technicians who showed up told me neither had installed this thermostat before. About an hour after they finished and departed, I realized I could not lower the settings -- or even turn off the thermostats (two zones). Nor did the company answer its phone (1pm). A recording provided an "emergency number" -- but its mail box was full. I called Honeywell customer service and a 30-minute on-hold wait later, got connected to a rep in, I believe, India. That's OK. Except the phone line went dead in middle of the call. All I had learned to that point was that if one removes the digital face of the thermostat (like some old car stereo units) it shuts off. To skip ahead several days, I got the consultant to come down and reinstall the wiring and settings...all seemed to be working fine, except...Lesson 2: Be careful with the digital face plate. This thermostat has a base that is screwed to the wall. You attach the various wires to terminals on this base plate. Then the digital face just "snaps" on and the thermostat comes to life. YOU MUST BE CAREFUL ON HOW THIS FACE 'SITS' ON THE BASE PLATE. There are perhaps two dozen tiny pins that must be carefully aligned and pressed into place. Unfortunately, one of the pins got slightly bent and didn't connect properly. The thermostat worked, except the supplementary propane boiler would not kick in (all geo-thermal systems have, or should have, a "supplementary" system). Yet another call (and fee) to a third company fixed this problem.Now that the installation is correct, I find the thermostat works flawlessly. I can control and program it from the free app. The daily and weekly programming is the easiest I've encountered. The Internet connection has worked more or less flawlessly.I'm rating this four stars because I believe the installation headaches, while partially self-inflicted, shows just how complicated it can be to wire up correctly -- at least for an older Water Furnace geothermal system.
This Thermostat Works Great
February 16, 2016
Unlike the older thermostats which are battery powered, the Honeywell RTH9580WF WiFi 9000 needs the "C" wire to operate. The "C" wire provides the needed power. For full functionality the wire between your HVAC unit and the thermostat needs to have 5 wires (C, R, G, Y and W) That is for a conventional gas system for heating using forced air and AC. For other systems, such as heat pump, check the manual which can be downloaded from the product page on Amazon or from Honeywell.If your wiring does not have 5 wires and you do not want to go thru the expense of pulling a new thermostat run, you do have a few choices:1. Reassign one of the existing wires to be used as the "C" wire. This will lose some of the fan control options.2. You can use the Venstar ACC0410 Add-A-Wire for all 24VAC Thermostats.3. You can use the Honeywell THP9045A1023 WireSaver Module for Prestige Thermostats.The third option seems to be the best. The cost of the Honeywell WireSaver Module is about half of the Venstar Add-A-Wire and it is a cleaner, more elegant installation.Now, if you read the User Guide for the thermostat you probably noticed in a few places where it says "Do not use K terminal. For future use". That statement is probably true for older versions of the thermostat and/or its firmware. Honeywell Support confirmed that the RTH9580WF thermostat will work with their WireSaver module which uses the "K" terminal.The only thing you have to make sure is that your heating/AC appliance's control board does provide the 5 connections needed (C, R, G, Y and W). I suppose that some older system may not provide all connections.The installation using the Honeywell WireSaver is straight forward. The attached pictures show it all.The RTH9580WF thermostat has all the features I need and then some. If you create an account on the mytotalconnectcomfort website and add the thermostat there, your thermostat will receive software updates as they are released by Honeywell to fix bugs and hopefully to add features. You can also configure to get email alerts and you can make changes to the temperature settings, fan settings and you can even edit the schedules. This comes in handy when you are not at home. Even when you are at home, it may be more convenient to make schedule changes on your computer instead of the small touch screen.You also use apps for your iPhone or Android phone. I am using a Lumia 950 (Windows 10 phone) and Honeywell has no app available. Also I am not aware of any future plans for such an app. Not a big loss though since I can access the mytotalconnectcomfort website using my Windows Phone the same way I do it on my computer.The only thing I find missing when I compare the RTH9580WF thermostat with others is the reports. It would be nice to be able to get reports about the power usage and savings via your email. These reports would add the 5th star.This thermostat works great for me. I only installed it about 24 hours before writing this review so I have nothing to say regarding the long term operation. However my past experience with Honeywell products was great.

Basic features, wifi works well, good deal.
April 6, 2017
Installed two in Les than an hour, work well.had to climb up to attic to turn off the power and connect the C wire. Setup takes a few steps, follow the instructions and be patient, you'll be fine.One of the unit had one loose wire socket, so one the wires is not secure but just sits there, may cause problems later on, too lazy too exhangeI've always had Honeywell in the past 20 years,they are basic features but reliable. That's what I like.Not getting those fancy smart device things, it is out of control, we will all be brain dead.
I wish the back light stayed on.
November 6, 2016
I ordered this to control a gas stove we put in our basement. I wanted a WIFI thermostat so I could remotely turn the heat up before we went downstairs for the evening and then automatically turn down at 10 PM when we go to bed. The thing I don't like about it is that you can't have the back light stay on all the time. I have a Honeywell touch panel one in the hall upstairs which controls the HVAC. That one you can have the light stay on.
WIFI Headaches - but works with limits
August 17, 2016
As a control freak and someone who occasionally forgets to change the thermostat before leaving for the day, this was an affordable solution that works for my needs. Haveing a similar Honeywell unit previously installed - the wiring was nearly the same. The biggest headache came from the WFI setup and im a damn computer tech. The bottom line is there must be NO SPACES in you WIFI SSID. I didnt test underscore ( _ ) but my assumption is it will not work either. Also, do not use special characters in your SSID (!@#$ etc) as they really arent supported.Another thing I didnt see mentioned in other reviews that i saw is that there is no data logging - you cant see what the high/low was yesterday or anything logging/data anywhere. You are literally just getting a Wifi controlled thermostat and for MOST people this will be enough. Abrupt weather changes/changing while on vacation/ easier programming schedules -- great for those instances. This will be a temporary unit for us until we replace our heat pump and air handler. Then we will decide on new WFI thermostat since there are rebates available. Most likely will not be another Honeywell unless their higher end stuff provides more control/data (logging temperature, prevent emergency heat, estimated costs, etc). In the end, i got what I wanted - a wifi controlled thermostat to change when I forget too. Now that I have it - i now know I want more
Nothing fancy, but a very solid device with some solid extras
May 12, 2015
Easy enough to connect (take pictures of the wires before removing old one) physically and then electronically to WiFi. Register the device with Honeywell and install the Honeywell app on your smart phone. Using the app (or even via the website interface) makes it much easier to modify the schedule. Plus, you can configure the device to send you an alert if the power goes out. It's hard to get excited about a thermostat, but this one worked where the Nest did not. We've got two of them and for much less than 1 Nest. The WiFi setup can be a bit daunting for those less computer savvy, but if you follow the manual it will work. One item of note, if you connect and then change your Wifi password or network settings - in the manual, it walks you through "forgetting" the WiFi settings so you can connect again. That is easier to do than setting it up, but you will need the manual to decode what the numbers mean.

November 13, 2014
I have only furnace at home (no A/C). There were three wires to my old thermostat : Rh, W and G. Rh was jumped to Rc, but probably not relevant since I do not have an A/C. I shifted G to C at furnace and used it for C at thermostat. WiFi setup was a breeze and I could remotely control the system now. 4 stars because of an issue with the website. I can't change the schedule online. It says "Schedule Loading It normally takes 10 minutes...." every time I visit. If it ever loads, I will update here. Let me know whether anyone else faces this issue.Update. The issue "schedule loading" persists. Customer support gave me two options 1) wait for a few more days or 2) a complex hacking/resetting method. I am not ready for the second method so I am still waiting. While waiting, I am giving three stars.Update (11/2015). Honeywell fixed the issue at server end. It works as expected on apps and websites. I recently had to change the wifi router password. Resetting wifi parameters is not straightforward - you have to press fan and up button and select item 39. I wish they explained this in the manual.
Great Idea
March 24, 2013
This is a great idea and, once installed, works like a charm. I was disappointed in that it cost me over $500 to have 2 of them installed. The website says its easy to install and I'm no stranger to electrical work, but for my situation (my house is 14 years old), I could not install it myself and it took 3 installers 4 hours to make them both work. That said, they do work great. I have been across the country and was able to adjust the temp settings in the house via my iphone. The programming was easy and quick and I think we are saving money on oil.

Clean, Easy To Install And It Works But Not Accurate In Measuring Temp & Humidity
December 31, 2016
I bought this in conjunction with a new furnace. The install was very easy and I had this wired in less than a minute. It was up and running on my network in about 5 minutes. The biggest pain is the setup on Honeywell's website. It would be nice if the registration was quick and easy but they require a lot of information which drives me crazy. That being said the app was simple to install and setup. The integration with my Amazon Echo wasn't as easy as I thought it might be but again, these parts of the setup don't impact the basic usage of the thermostat. So minus one star for the app/web configuration part of the install.

The one thing I don't like which is why knocked off an extra start is the temperature is off by 2 degrees. When the thermostat is set to 72 degrees my old thermostat, as well as two AcuRite thermometers/humidity monitors I put in the same room read 70 degrees. The humidity guage is also off by around 8%. It really doesn't affect the furnace operation and is more annoying than anything else so I'm pulling a star on this review.
Disconnects from SmartThings about once a month.
September 25, 2016
Disconnects from SmartThings about once a month. I purchased this thermostat because I preferred the aesthetics over others on the market. However, about once a month (because of software updates I presume) it disconnects from SmartThings and I have to go through the painful process of reentering my Honeywell login information to get it back online.

Additionally, as other reviewers have mentioned, the mounting bracket is poorly designed. You have a 50/50 chance that your thermostat will hang loosely because the bracket doesn't grab the thermostat well enough.
Fancy version of a standard stat
July 23, 2016
Fancy version of a standard stat. Wish I would have bought the Nest as it does metering, motion, phone detection, etc to truly drive cost savings. This item just gives you remote access to the unit nothing more than that in my opinion.

I should have looked at new Nest reviews, since the updates and changes that product is solid. Three of my friend have it now and it is 10x the product this is.

Easy to install, requires common to be hooked up to power it. Had to dig that out of the wall as many stats do not require the common to be used (including the Nest).

I will be moving this stat to the other zone and adding a Nest to my main zone. They wont talk but that is fine as the secondary zone doesn't run much in this house.
worked for 6 months, died, honeywell refused to replace, warranty not honored
January 16, 2016
I researched the thermostats to death. I had no reason to replace the old Honeywell thermostat that came with my house. It looks like it is the original thermostat that came with the house when it was built 30 years ago. So in my research I considered the Nest thermostat (and I really wanted to get it), but I settled on the Honeywell mostly because I wanted the option to set my own schedules rather than have the device "learn" what I like.

I purchased the Honeywell 9580 in June 2015. I promptly installed it on my wall when it arrived to replace the original Honeywell unit that came with my house. We added the device to our wifi network. My SO and I then downloaded the "Honeywell Total Connect Comfort" mobile app, configured the account, and created our schedules from the app. At this point there was no reason for us to ever touch the thermostat on the wall again.

In fact, we didn't touch the thermostat after we had the mobile app working. We enjoyed the ability to adjust the temperature, power state, and schedule of our fancy thermostat from anywhere. Hell, we even turned it off and on from the airport when we were going on or returning from trips! It's wonderful to come home to a sufficiently cooled/warmed house!

Then the problem arose.

One morning (Jan 2, 2016) I came downstairs to find the the color scheme had changed on my unit. I had asked my SO if she had changed it, but she said she hadn't. I tapped the screen to change it back to the color scheme that we prefer. To my surprise, it changed back to our color scheme immediately when I tapped the screen. Odd? I went about my day.

Later the same day I received an alert from the "Honeywell Total Connect Comfort" app stating that my Honeywell device was no longer connected to the internet. Wow! I'm impressed! Great feature indeed! So I wander over to my thermostat and discovered that the screen was black. Very odd. I tapped the screen - nothing happened. I tap the screen again - still nothing happened.

So then I called Honeywell Support. They had me pull the thermostat off the wall and check the circuit breaker and also check to see if there is power across a couple wires. The circuit breaker was fine. There was no power across the lines. Honeywell Support then told me to contact HVAC to find out what's wrong with my furnace.

I contacted a local contractor service which came out the following day. They "jumped" my thermostat, installed my old thermostat back on the wall, and told me that one of the transistor caps is damaged on the fancy Honeywell 9580. Sure enough, it fell out just flipping the thermostat over.

We called Honeywell Support again to report that the device is still not working after HVAC checked it out and that one of the transistors is now "broken". Honeywell Support essentially blamed us for the physical damage and explained that they would not honor their warranty as a result. We explained that the thermostat worked perfectly for the 6 months that it had been on the wall and the only reason it was off the wall was because it STOPPED WORKING and a HONEYWELL SUPPORT REP instructed us to take it off the wall. So how does it get damaged sitting on a wall for 6 months? Honeywell provided us with the email address of a "manager" named Paul Arntzen (case # 00168634) and instructed us to take pictures of the device and email that "manager." We emailed Paul on January 4th. We received no response. We emailed him again on January 8th. As of today (January 16th, 2016), we still have not received any response.

IN SHORT
The device worked perfectly for 6 months and we did love how it worked. However, due the to crappy support from Honeywell, we will not be purchasing Honeywell products anymore.

EDIT
We eventually did get it replaced for free, but it took at least a dozen emails and several phone calls. YMMV. The way that we got results was that we used the "feedback" option on Honeywell's website. Someone got in touch with us, provided us with an email address of a manager and asked us to send pictures of the device and details of our story. We did. Someone responded and asked for our address. Shortly thereafter a brand new device arrived at our door. We put the new device into operation and it has worked without issue thus far. We kept the original Honeywell thermostat (30 years old and non-digital) just in case we get a repeat issue. I ended up selling the old broken thermostat on eBay for a decent amount of money - the person who bought it apparently fixed it and he is happy with it. Changed from 1 star to 3. I can't in good conscience give this a 5 star rating due to the customer service.
Pretty but caution !
November 13, 2014
If you have a Gas Furnace with Hot Water Heat -- BEWARE -- nowhere will you read this on Honeywell's website, however you will require an alternate 24v power source (not run off the furnace). Why? Because the Gas Furnace will briefly power down when a "call for heat" happens. This reboots the thermostat. Called Honeywell -- They knew about this problem immediately -- get calls all the time. However, you need more than just the "C" wire to solve this problem. You need to run a 4th "RC" wire, and go buy a 24v transformer to power it. This was a very bad decision by Honeywell not to tell people about this upfront. Luckily I ran 2 extra wires, but if you run just a C wire you will be quite upset to find you will need another wire run. Honeywell could have added a $1 capacitor to the design to solve this problem, however why do that when they can have me run more wire and buy a $20 transformer.

Also, for those thinking this will capture utilization metrics, like "hours on per week", or an activity log of some kind. Nope. A $200 thermostat that looks pretty. Guess I'll have to contact the NSA to get that data.

Wake won't work earlier than 2:15 AM. Poor documentation and customer support.
May 16, 2017
This model works well and the app is fairly easy to use. I would have rated this a 4 or even five except for two things:1. The Honeywell documentation is weak, particularly from a troubleshooting perspective, and the phone support is even worse.2. This model has a software bug that does not allow the wake time to be set at 2:00 AM or earlier. The wake set-point will be ignored if set earlier than 2:15 AM. Email support claims this is a "calibration", but this "feature" isn't documented and I have used several other brands of programmable thermostats that don't have this handicap.
- Easy Installation - Easy Configuration/scheduling
July 20, 2016
Pros:- Easy Installation- Easy Configuration/scheduling.Cons:- Loud clicking sound each time the thermostat starts/stops the AC (Very annoying).- Cannot control using local WIFI (LAN). You must control via internet using mytotalconnectcomfort.com website.
Not sure it's worth over $100...
October 19, 2015
Product is okay, but could be better. Their controller app for Android is very, very basic and needs a LOT of work, but it functions for VERY basic stuff, if you don't mind it crashing and having to restart a lot..I do wish, though, I had waited 2 weeks, as the price dropped $10.00.Yes, I would very likely still buy it, as I live in the Desert southwest and need to reduce my power usage to as close to zero between 3:00 pm and 6:00 pm. But any programmable t-stat will do that.If their wifi app interface was better, it would be worth 4+ stars,,
Good luck with the WiFi
April 24, 2015
As other reviewers have noted the set-up of the WiFi is no simple task. I do not knopw what the problem was the first two time I tried but finally had success on the third try. The biggest frustration was getting it into "Wifi set up" mode. The in structions said that if "when" the set-up fails you need to pull the unit off the wall for 10 seconds and it should start over. In my experience this did not work even when it was unplugged for over 5 minutes. There should be way to force the unit into wifi set-up without pulling it off the wall. On the programming front it was very tedious until I noticed the option to set multiple days to the same schedule. Too bad this was not explained from the start so that I could have avoided the frustration of setting up Monday, Tuesday and Wednesday on the same schedule.
Honeywell Tech Support is Laughable
March 6, 2015
This product worked as advertised eventually. Tech support from Honeywell is essentially non-existent. The thermostat apparently is not compatible with my Zyxel router from Centurylink. Called tech support and they could only read me the manual before hanging up on me and not calling back even though they asked for a call back number. When I called back, the new tech had never heard of a firewall. You will need to have someone who is internet tech savvy to make sure the WIFI hookup will work. In some cases, router ports may need to be opened. I had to disconnect and essentially reformat the thermostat about 8 times before it worked. Most was due to the router incompatibility.
Good product. A few quirks.
June 16, 2014
UPDATE: After two years, it started behaving erratically (maybe got fried in the same storm that took out my computer?). In any case, for a replacement I opted for the Sensi UP500. After using the Sensi, I've lowered my rating of this product from 4 to 3 stars. See my review for that product.Basically, it does what it's supposed to. It's relatively painless to install (assuming you have the correct wiring setup and wireless network). And when combined with the app and online access, it's very easy to use.The mobile app is pretty good, but (annoyingly) requires you to login with an 8-digit password every single time you launch. And it's missing some really no-brainer features, like a "change filter" reminder, or the ability to automatically switch from heat to cool, based on a temp range. Or location awareness (my phone knows when I'm home, so why doesn't the app pass on that info to the thermostat, and adjust the temp accordingly?)The website is a little clumsy (it's not at all clear how to get from the landing page to the schedule). And I was really disappointed to see there's no data tracking (How long was my system running over X period? etc, etc).But for a fraction of the cost of competitors, it's hard to complain.USER TIP:I noticed shortly after I set the schedule, that the AC was turning itself on BEFORE the time I had it scheduled to go to a lower temp at bedtime (up to an hour early). I couldn't figure out why, so I contacted support. This is the email I received:[Adaptive Intelligent Recovery, also known as Smart Response, is a feature that allows the thermostat to turn on the system earlier than programmed, so the house is at the programmed temperature by the onset of the comfort period. // The Adaptive Intelligent Recovery feature calculates the recovery ramp based on the number of degrees away from the desired set point and previous equipment performance. The recovery ramp determines the optimum time to turn the heating or cooling system on. If the set point is reached too early or too late, the ramp is adjusted for the next day's recovery, until the set point is achieved at the desired time. // It is necessary to allow the thermostat at least 10 days to "learn" a new program. If the set point is adjusted or the thermostat is switched to off during the recovery period, the thermostat interprets this as a new program input, and the learning period restarts at day one. Please be patient while your thermostat is in this learning phase. // If you would like to disable this feature, press and hold the Fan button and the up arrow key for five seconds. The screen will then change, and you will see two numbers appearing. Press the Next button until the number on the left becomes 13. Use the arrow keys to change the number on the right to 0, then press done.]

It works, but it is not accurate.
February 19, 2017
I have owned this unit for less than two years, and it recently began reporting our indoor humidity quite inaccurately (6-8% lower than actual level). I contacted Honeywell customer "service" and received this reply:

"RTH9580WF does not have the feature of controlling humidity from the thermostat, it just displays the humidity settings on it. There is no option to calibrate the humidity settings on the thermostat. This thermostat can display 5-6 degrees off when compared to a hygrometer.

You may get the unit replaced from the place of purchase, however it will display an off of 5-6 degrees."

Be advised, it is inaccurate, and Honeywell will do nothing about it.
A lot of money for a thermostat that lasted less than a year an a half.
September 24, 2016
I purchased this item in April 2015. It worked great, I loved using the app to change the temp settings. One of the reasons I bought this particular model was because it had a lock screen, so I could try to keep the teens in my house from changing the temperature (all claimed it wasn't them that changed it). That feature is very poorly done, very difficult to unlock the screen when needed, then you have to go back in and change the settings again to lock it. Better would be to unlock it then have it time out after a few minutes.
Anyhow, I was still happy with my purchase, and even bought another Honeywell thermostat for my downstairs, though not this model,just a basic wi fi model, so I could control my whole house with the app. The basic model is about half the cost of this one, and does everything this one does, with the exception of the problematic lock feature. So it doesn't have the fancy touchscreen, not really necessary for function.
Anyhow, just a few months after I purchased the second thermostat for my downstairs, this one just failed. Unfortunately, the 12 month warranty is 5 months expired. I am not sure what actually failed in it, but it would turn on the compressor when the air should come on, but then it would turn off again just a minute later. Using the downstairs unit the compressor would stay on as it should. I confirmed that it was the thermostat and not something else by re-installing my old basic thermostat that I had kept. Things worked perfectly with that thermostat installed, so not my HVAC unit.
This is a lot of money for a thermostat for it to last less than a year an a half. Now I'm upset I bought another of the same brand for my downstairs, as I was trying to avoid using two different apps to control my two units, but I can't bring myself to purchase another Honeywell at this time. Maybe I'll get a Nest.
Thermostat with it's own mind.
May 12, 2016
Bought this unit to replace an older Honeywell Wifi thermostat because I wanted scheduled fan control times to circulate the air. Install was a breeze (although paint and drywall touchups were needed; this unit barely covers a 1 gang box) due to already having the correct wiring.

The touch screen is a bit annoying .. using the back of a pen or a key is much easier than trying to use your fingers sometimes.

Biggest complaint is the temperature sensor. As other reviews have noted, it's a bit schizophrenic. It's also very slow, or very fast to respond. In most cases, you will experience a 3-5 degree fluctuation in the room temperature before the sensor even registers a 1 degree change. If you can handle that, then this product might be for you. If you rather have a thermostat that works but doesn't look as pretty, check out some of the older (cheaper) Honeywell Wifi Tstats.

I have 2 of these, and they behave the same. I have several older models also installed in other buildings which are much more stable on the temperature readings, resulting in much better climate control. The lack of stability isn't awful, just annoying. I'll keep using these because the scheduled fan control is an important feature (which I'm sure they could add to their older models, but they'd rather force you into upgrading to a far less superior unit).
Worked great for 9 months then began blanking out for hours at a time.
December 26, 2015
Purchased the Honeywell Wi-Fi Smart Thermostat in January of 2015. Worked fantastic for 9 months then my spouse reported that the display was blank one evening while I was away ... sure enough I could not connect to it via my smart phone during this 'outage'. A few hours later the unit came back to life - no explanation for the system outage. During this time, the thermostat is unresponsive ... so temperatures in the house start to get uncomfortable very quick. It's been doing the same thing for several months now ... sometimes it blacks out 3-4 times a day while other times it seems to work okay for several days in a row. Very disappointed with the fact that I cannot return the item even for a partial credit. Something is certainly wrong with it ... I've reset it by removing it from the wall ... no help at all.
Worked for 15 months
April 11, 2015
Well it worked great for just over a year. Bought it in January 2014 and it stopped working today, April 11 2015. It has a 1 year limited warranty so its out of warranty, but it states, "This warranty shall not apply if it is shown by Honeywell that the defect or malfunction was caused by damage which occurred while the product was in the possession of the consumer." Honeywells customer assistance definition of that is once you buy it, install it, and it works, warranty is void.

For the most part though for the last year my bills have been almost $30 to $40 cheaper this past winter than last. Never went a summer without the Honeywell in this home so I have no comparison there. It does what it is suppose to do, but mine pooped out just a couple months after the warranty. My problem was that it would not turn the furnace on anymore. It would work with the AC and the fan. I put in my old thermostat that I still had luckily and it works just fine. Put Honeywell back in after that, and it wouldn't work.

Spend a Little More on a Better Thermostat
September 16, 2017
Very difficult to connect with Windows--actually I never did get it connected. The description does not say that you need a "C" wire--only when you open the installation manual does it mention that. The manual also doesn't say what a "C" wire is, or where to get one (you need a separate transformer), which means another wire in the wall. The customer service video was no help, nor was the call-in customer service. I ended up returning it and getting a more expensive, but more user-friendly brand.
C Wire is a must! Caution!
July 9, 2017
Well it looked good, felt good but you know what? I wouldn't recommend it in an older home.Why?THAT DARN C WIRE!!!Yes, they have instructions on how to bypass the C wire and make it work, but you give up manual control of the fan, and you have to make concessions that you don't have to make with some other brands. There's a difference between a thermostat that works well, versus a thermostat that you have to make work. Being that I would have to "make it work" versus simply wiring it in and being done, I chose to return this product and buy another.
Mostly wonderful but unusable, had to return
May 30, 2017
This is a tough item to rate. I loved the ease of installation. It was up and running within minutes. It connected to Alexa without issue. The interface is excellent. The Honeywell app is very usable. However, I had to return it. The temperature differential, otherwise known as the cycle rate, is +/- 0.5 degree. This thermostat was turning my compressor on and off within 5 minutes only to do so again within a minute or 2 when the temp went back up a half a degree. It probably cycled at least 10 or 12 times in an hour. That kind of constant on/off pulls a lot of power unnecessarily and causes additional wear and tear on the hvac system. Honeywell service center days that there is no way to change the differential and it is set that way to maintain as accurate a temp as possible. I returned this unit and purchased an Emerson SensiSmart. That unit allows the owner to set the cycle rate to slow, medium, or fast. I rated this one at 2 stars because in my opinion it is unusable, but I can see how other people might prefer this level of accuracy and, as I said at the beginning, I love everything else about it.
Ticks all the boxes, but serious quality issues
December 9, 2016
Minimally, the thermostat works. Several gripes will keep me from buy any more, however:1. I'm not sure the quality is there - In 3 years I've had 1 DOA, 1 quit working completely, and 1 quit working reliably.2. The Honeywell iOS app doesn't always work reliably.3. It's kind of dumb that a smart thermostat can't set its own time from the Internet.
Great thermostat, horrible service behind it
November 18, 2014
Great thermostat, horrible service behind it. This is about the application service to remotely control the unit. When it works, it works great, but it has a frequent down time, and the folks at Honeywell don't seem to fix things that happen on their servers after hours. Just last night/this morning, it was down for about 12 hours. The application would throw an error that it can't connect to the servers. Tried on multiple devices, networks, all the same. The thermostat is on the network (i can ping it). Then suddenly after 8am this morning, it starts working again normally. I will also get notifications that the thermostat is offline, but I can see it on my network. I wish there was a way to override the remote access and go local network access only. Fortunately, the thermostat just continues as it should connected or not and you can control it locally.
Constantly have to reprogram
August 24, 2014
The thermostat is fine as a wall thermostat, but the Wi-Fi remote connection is very unreliable. If the home Wi-fi drops even for a moment the thermostat needs to be reprogrammed and the remote connection will not work until it is set back up. The occasional convenience is not worth the aggravation of physically reprogramming the thermostat every week. Do yourself a favor and find something more reliable.

I don't know who else bought this thermostat but I am wondering if your unit turns off a random times and then turns back on. Mine is doing it but I can still use my phone to turn my heat on but it resets my schedule that I had programmed. Weird I know. But is anyone else having this problem?
One fatal flaw
December 8, 2016
This product has many nice features;
- It installed easily / instructions were great!
- It looks great on the wall
- It's easy to use

However, and this is a BIG and ultimately fatal however
- If the product looses internet connectivity, it may not, and probably will not, reconnect without personal / onsite interaction.
- This was confirmed with a call to Honeywell tech support

I purchaced this for a vacation home where I could remotely monitor interior temperature over extended away periods of time. During the last Honeywell initiated internet update, I lost connectivity and have never been able to reconnect, making this product useless. I have a Nest remote thermostate in our other home, and have never had this issue, even with internet outages. Unless you plan to always be present to reconnect your thermostat from time to time, I recommend you look at other brands

Update: Problem solved / replaced with Nest!

Note: I had requested to return this thru Amazon back in November, even though I could not do so until I returned to our vacation home in June. June was well past the allowable return period. I printed out the return label in November. Removed and returned the Honeywell product when we got back to our vacation home and received full credit. Amazon rocks! Why would you ever buy from anyone else!
Didn't work for us!
July 30, 2016
This thermostat did not work - at all! It heated the house rather than cooled it. We tried it a few times and each time it was a bust! We had to put our old one back on. On a side note - the customer service was really good. And so was the return.
Disappointed
February 19, 2016
Very disappointed. It was awesome while it worked but it died after 14 months. Honeywell support was horrible and their response was to simply buy another one because "it happens". Well no thank you. Replaced it with Nest and so far I'm very happy. Especially since they have a 2 year warranty!
HORRENDOUS CUSTOMER SERVICE
June 16, 2015
Worst customer service experience I've ever received. I was on hold for 45 minutes until I got a supervisor. I called because my unit broke and was still under warranty. I called once and troubleshooter with Honeywell's tech department and the unit still did not work. I called back this second time and was told I had to go through Amazon.com for the warranty. When I called Amazon.com they told me it was Honeywell. So I called back with Amazon.com on the line, which is when I was on hold for 45 minutes. They still haven't honored their warranty because they need me to troubleshoot it AGAIN! I'M GOING NEST OR ECCO NEXT TIME!! NOT WORTH MY TIME AND AGGREVATION.

Could not get thermostat to work with standard HVAC a/c-gas heat system. Used a transformer to power "c" wire and unit powered up, but would operate properly. Had to return to Amazon.
when i installed the thermostat it tried to set itself on fire. but the single star (should be no star) is for the dealer.
October 14, 2017
when i installed the thermostat it tried to set itself on fire. but the single star (should be no star) is for the dealer, not the thermostat.In late march of 2017 i bought the "good as new used" honeywell wifi, programmable thermostat (RTH6500WF), from EverythingDeals, The package it arrived in looked fine and the unit looked new.. I didn't remove the thermostat from its package because it needed the "C" wire attached and my furnace system didn't have one. I decided to wait running the C wire until this fall because there was little need for the thermostat as it was intended to replace a working older one.this month i got around to running a pair of wires to the thermostat location. (C and Rc). as per the instructions I attached the two furnace wires to R and W and the two new wires from a 24 volt transformer to C and Rc after removing the jumper between R and Rc. triple checked to be sure the four wires were in their proper placement in the wall plate. checked to be sure the voltages were correct.When i plugged in the thermostat to its wall plate the display did not light. in a moment i smelled hot electronics and immediately pulled the thermostat off the wall. part of the plastic housing was very hot and had started to bubble. And there was something rattling around inside that had not been rattling before. not sure what happened, but clearly this was not a good as new thermostat.in talking with honeywell's overseas support about getting it repaired i was very nicely told i had to deal with the seller (EverythingDeals) to get it repaired, replaced or returned. But of course EverythingDeals has a "we don't care what happens after thirty days" policy.the galling thing is i had previously installed a honeywell T5 wifi thermostat and had no trouble doing it, including running a pair of 24 volt C and Rc wires to it. the install was no more difficult for the rth6500wf than it had been for the t5. the wiring was the same. the places for the wires on both units were well labeled and labeled with the same letters.so - bought a second t5 from amazon. used the same wires in the identically labeled sockets (removing the jumper) installed it with no problems (no burning) and it works as advertised.perhaps i am wrong but it seems sensible to think the unit was never tested to see if it actually was good as new. buyer beware.

Dangerous--can cause system to go into uncontrolled overheating

They die and when they die, they can cause big problems. I had one randomly change the set up program and instead of cooling, ran the heat pump up to 95 degrees before I returned to the house and found it--the heating contractor figured out what happened (that happened 4/22/17). Another house on 4/27/17 (fifty miles away from the other failure) suddenly went to heat while the thermostat was set to cool. Even turning the thermostat to OFF didn't cure the problem so I had to turn the furnace off. I've owned five of these over the past four years and used them in three separate locations; four have failed.
