    Smarter Than a Lot of People I Know

    Our furnace, air conditioner and thermostat were all replaced in 2006, in a house built in 1985. I don’t remember if the thermostat wiring was replaced at that time or not. Our current thermostat is a very simple set-back thermostat that runs on alkaline batteries and does not use a C wire. I happen to have all of the manuals and installation instructions for all of our HVAC products, and that helps to sort out the installation and set-up process of this Honeywell thermostat. Our high-efficiency Trane brand furnace has a C wire terminal, marked “B/C”. The old set-back thermostat required four wires to hook it up, but luckily our thermostat wiring is a five-conductor cable. To install this Honeywell RTH9585 thermostat, I only had to utilize the unused fifth wire in the cable and hook it up to the appropriate terminal on the furnace circuit board and I had my needed C wire connection (this is a simplification of what I actually had to do, but in essence is what the end result was). This made me happy because if I had to use the alternative hook up with the green wire, I would lose the ability to use the fan continuously (according to the “C Wire Addendum” that comes with the User Guide) and that is something that I occasionally do depending on the season and the weather. When mounting the thermostat wallplate to the wall, check to see if either of the screw locations will hit a stud (one of mine did) as the included screws are long enough to pass through typical 1/2” thick drywall. If you just go ahead and drill two 3/16” holes for the drywall anchors, and hit a stud, the 3/16” hole drilled will be too big to use the screw by itself. If a hole lands on a stud, drill a 7/64” or 3/32” hole and you can use just the screw without using the plastic anchor. The thermostat body snaps onto the wallplate with a lot of pressure. I suggest snapping the thermostat on and off the wallplate numerous times before mounting the wallplate to the wall as this will make it easier to pull the thermostat from the wallplate in the future if you need to remove it. The one thing missing from this thermostat is a larger wallplate trim ring to cover holes left over from the old thermostat installation. I fabricated my own from a piece of sheet styrene purchased from a hobby shop (see picture). My old Lux thermostat came with one, and I’m guessing it would have cost Honeywell less than $0.25 to include one. Kind of an oversight on a $200 item if you ask me. Once you get over the wiring hurdle, installation, set-up and programming of this Honeywell thermostat is really easy. Their web site is well done, the instruction manual is well written, and the menus and walk-through on the thermostat itself are all exceptionally well done. Honeywell, whose name was once synonymous with home thermostats, I feel has been under pressure in recent years from a number of different thermostat manufacturers, but they have really redeemed themselves with this model. The only thing that is really missing is geofencing capability, but after doing some reading about this feature, I’m not so sure it is something I would find useful. I have had a few times where the app on my phone appears to be unresponsive to my commands. If I close the app and reopen it, it works fine, so I have gotten in the habit of closing it once I make my adjustment and then open it again in the future when I need to use it. We are also having a little difficulty figuring out how to set up my wife’s phone to allow her to make remote adjustments to the thermostat that is registered with my email address. I’m sure it is something simple we have overlooked, but it is a little frustrating nonetheless. The main thing I like about this thermostat versus the competition is all the information that is displayed on the screen “at idle”. When you haven’t used the thermostat for a bit, the display dims slightly, but is still very legible without needing to be touched. The following information is available on the “Home” screen without having to scroll through different displays and/or menus: current temperature, set temperature, outdoor temperature, both indoor and outdoor humidity, current time, and the time when the next programmed change takes place. A quick tap of the outdoor temperature gets you more current weather details and the forecast for 6 and 12 hours in the future - quick and easy when you are headed out the door and want to know the need for a coat or umbrella. The RTH9585 is a very full featured thermostat that can do just about anything a homeowner would want or need an HVAC controller to do. I’m going to just talk about the features for residential use. Business use is the other alternative, but I suspect most business owners will just have a contractor install a thermostat of the contractor’s choice and won’t go shopping for one on their own. Obviously the thermostat can follow a set schedule of temperature changes for each day of the week (meaning each of seven days can be different from the others), but you can also change from the typical four schedules per day to just two if that is all you need. There is a fan option to run randomly about 35% of the time to circulate the air in the house. This is a nice option compared to having to run the fan continuously (which is still an option with this thermostat). There is a setting for the thermostat to change over automatically from heating to cooling. There are reminders for the filter and humidifier pad. You can set a vacation hold until a certain date and time and the thermostat will heat or cool your house for your return. There is a mode to allow you to clean the screen for 30 seconds without disturbing any settings. There is a lock mode that allows partial lockout (only temperature can be changed) or full lockout and you can also set a password to unlock the thermostat. Honeywell’s “Smart Response Technology” that anticipates ramp-up time to reach a given temperature by a specific time gives you the option of turning this feature off. The display can show Fahrenheit or Celsius temperatures and 12-hour or 24-hour time with Daylight Saving Time turned on or off. There are also settings specific for using the thermostat in a business setting. The thermostat will work without Wi-Fi, but you do lose some of the features. You can also set your account to send you email alerts if the temperature or humidity go outside of the range you specify. The phone app also gives you the option of voice control and the Honeywell Total Connect Comfort App will interface with Amazon Alexa, Google Assistant, IFTTT, and SmartThings. Oh yeah, I almost forgot, you can change the color of the screen to match your decor. Ours is set on black background with white lettering as I like easy-to-read contrast since I have gotten older. I can recommend this thermostat to the average and above do-it-yourselfer and I don’t think there is anyone who would be disappointed with the feature set this product offers.

Touching the Button will Display Instructions to Resolve the 'Alert', Accordingly. * Clean Screen Option Under Settings – Your Touch Screen Will Eventually Need Cleaning, but You Don't Want to Change Any of Your Scheduled Settings – This Will Do That. In my humble opinion I think that the most important settings are the Programmable Daily Wake, Away, Arrive, and Sleep Settings. They allow you to set your T-Stat temperatures back to lower, 'Unoccupied', and, or higher, 'Occupied' temperatures for comfort and $$ Energy-Savings. For example, if you and your wife are away for approximately 10 to12 hours a day from home – you can set the temperature back to around 5 degrees under your 'comfort' level for both heating and cooling. Think about it – that's approximately 300 hours a month your home, apartment, or condo is setting back the temperature. It will save you Money on Your Electric Bill. And, over time this Honeywell T-Stat can easily PAY for itself, while still providing you all the temperature comfort you demand. After using this Honeywell Wi-FI-Color T-Stat for over a week now I am convinced it is the best climate-control device for my home. I love it. It is an easy Learning-Curve – the more you use it, the easier it is to understand and take advantage of all its comfort, and, money saving features. I highly recommend this Honeywell WI-FI Color Smart Thermostat, RTH9585WF for any geographical region or climate. This T-Stat allows you to take control of your individual needs and comfort all the while it saves you money on your electrical bill, and PAYS for itself in time. A WIN-WIN!

    Disclaimer: I have central air with a TRANE gas heat furnace, already on a battery-powered digital Honeywell thermostat which only has basic thermostat operations. My installation story - problem and apparent fix: Upon receiving this new thermostat, I uninstalled my previous "regular" Honeywell thermostat to find my current system connected via 4 wires (green, white, yellow, and Red [Rc]). This new thermostat requires a power wire, or C-wire, to be connected from the gas furnace (in my case). Luckily, the wireset "sheath" that my thermostat uses has 8 total wires inside, so I simply connected this new thermostat to the same connection points as the previous thermostat and then connected the already-present blue (power) wire connection to this unit and the gas heater. Upon connecting, I flipped the breakers back on, set up the thermostat, set the display colors and wifi tech info, and I was set. One problem: The fan didn't turn on even though the unit showed it as "Fan on". I checked all my connections - they were ok. I called Honeywell tech support. They said everything was wired correctly and that it was likely a TRANE issue. I called a TRANE technician, and he stated it was wired correctly over the phone. I started from scratch and went through setup again - same result. I tried going well above and below the current 65-degree temp to see if the A/C or the heat would trigger the fan to actually run. It did not. After waking up the next morning, I decided to check the wiring inside the thermostat and everything was tightly connected. Upon placing the thermostat back on the base unit, the thermostat went though its checks, initialized the system, and eventually turned on WITH THE FAN. After speaking with another Honeywell representative, it appears that the unit just needed to be reseated in order for this "glitch" to clear as no wires were changed, tightened, or moved during this process of removing and reseating the thermostat unit to the base plate. Very strange. OBSERVATIONS: The unit works and looks great and is easy to operate. You can operate via the Honeywell Wi-Fi app, your PC browser, or the unit itself. It can be operated from anywhere by using the app/PC. Setup for temperature scheduling was simple. The fixture itself has a brightness/color/hue setting which is set for both active and passive modes. Active is when you are currently touching the screen... passive mode takes affect after 5-10 seconds of not touching the screen. The current temperature is displayed in the middle of the screen which is very easy to read from a long distance away. Display also shows indoor humidity along with outdoor temp/humidity. The unit itself is rather small. Keep in mind that if you replace a bigger unit with this one, you will need to check the paint behind your previous unit, or in my case, an electrical box like the ones used for light switches/plugs but mounted horizontally. There was actually a small hole visible on one side of my unit, so I'll need to fill that in with some spackle and then paint. If your thermostat is in a very visible area, you may want to consider this prior to installation. I have requested Honeywell to develop some sort of frame (or multiple frames) to go around the unit for cases such as this. Then wall repair or painting can be totally avoided. Overall, the thermostat is working great. Other than the "glitch" of the fan not blowing until I reseated the unit to the base, it has worked fine. The touch-screen is awesome and put together well. Arrangement of options on the display are perfectly placed. And the ability to check or change temperature at anytime, anywhere is a huge plus. Great job, Honeywell.

    As the title says, this thermostat is so easy to use, my mom (a grandma) can control it. I bring this up because for years my mom struggled with the basic digital thermostat that came with the system. The old thermostat had a numerical monochrome display that she had a hard time seeing, on top of not being able to remember which direction to press the arrows. All that confusion is gone with this Honeywell Thermostat. It has a decent size (about 4 inches) back-lit color screen that she can easily view. The way the temperatures are presented (laid-out) on the main screen is clear and intuitive. The larger number positioned in the center of the screen is the current temperature inside the house. And the slightly smaller number to the right is the temperature you can set your air conditioning/heater at. She simply has to read the words "Indoors" and "Set To" above the respected temperatures. This simple language has made all the difference in allowing her to run her HVAC system properly. And like with all new technology, she was a little hesitant at first using the touch screen, but the interface is well designed, and she got used to operating it in no time. Installation was very simple. Our system had a C-wire, so there weren’t any modifications needed. If you end up finding out that you don’t have a C-wire, the instructions provide an alternative installation process that allows you to use the G-wire in place of the C-wire. The G-wire normally controls the operation of the system’s fan, but if it used as a substitute for the C-wire, then the fan can no longer be used independently. What this means is that the fan will only turn on/off when the air conditioning or heater is running. If you never run the fan independently, then this won’t be a problem. If you would like to maintain that functionality, then an electrician will need to install a C-wire on your system. Honeywell’s website provides a lot of information and videos regarding this and other installation topics. Our electricity bill ended up being lower this month (22% lower) compared to the same month last year (see image). It’s hard to say how much of the improvement in usage was due to the thermostat, but that was the observation for the first month of use. Considering all the outside factors that come into play, like the weather, one factor that may have led to better efficiency is the accuracy of the thermostat sensor itself. The old thermostat’s sensor may not have been as accurate, leading to the system running longer than necessary. The sensor on this new thermostat may be more accurate. I did notice the system not taking as long to reach the desired temperatures we selected. And finally, the WiFi enabled functions work very well. It was simple to setup and initialize, and easy to manage over the computer and Honeywell’s app. I was ready to assist my mom remotely if she needed help using the new thermostat, but that assistance was never needed. Overall, I’m very satisfied with this unit, and would recommend it to others looking to upgrade their thermostat.

    Functional, integrated, and pretty

    I've had different Honeywell thermostats over the years, almost exclusively. What sets the Honeywell apart for me vs other thermostats is the fact that they always just work. That said, they also seem to be all cut from the same cloth. You can see that even in this top tier model. The RTH9585WF model is the newest in the series of the WiFi Smart Color thermostats. Unlike the Lyric series, this series is a simple programmable model without the geofencing and other interesting features of that series. The Smart Colors claim to fame is found in it's name, the various colors chosen as backgrounds. While that may sound a bit vain, it's a concern for some who would like to color match their interface with their decor. I found the default blue to be a nice color, but there are many shade to choose from. You can also pick a custom color. The adjustments for custom allow you to pick thousands of shades. The general functionality of the thermostat is pretty solid. You get a large current temperature, along with the current set temp, and outside temperature. Touching the outside temp gives you a 3 period (current +6 hours and +12 hours). The default schedule is a great starting point for most. You can easily customize it and setup different schedules for each day. You can even set a temporary schedule to override. Since my family situation leaves someone at home most of the time, the programming features go to waste. The good news is that it's easy and fast to switch the thermostat to temporary hold and/or permanent hold right from the home screen. One feature that's pretty unique to honeywell is the Smart Response technology that learns how long your system takes to heat up, so that you can set the schedule to what temperature you want when you want it instead of having to compensate for the time. I've used this in other Honeywell thermostats to great effect. The touchscreen is definitely resistive, but responsive. The wifi connectivity seem solid and the Alexa integration is quite useful for my household. The app is ~ok~ and gives you the ability to adjust the schedule, current settings, and view a 5 day weather schedule. The Marketplace section of the app is initially just trying to sell you more things, so it's kind of a waste of space. Initial setup was quite difficult for me, as I lacked a 'C' wire. Luckily for me I had a bunch of extra wires, so it was just crawling under my house and patching into one of the 24v wires on the transformer. If you're handy and not scared of a little wiring, it's no big deal. Hopefully it's easier than my system, as my old Goodman from '97 required some pretty manual wiring. I patched a blue wire into my air-conditioning hookup and was in business. Once powered up, it was a simple manner of following the initial setup. WiFi setup was painless, but typing a password in on the screen was a bit awkward. Good news is it keeps programmed even if disconnected, so it's a pretty one-time affair. This pattern of initial pain was continued when it came to registering and pairing the thermostat for online features. After you register you need to input both a mac address and CRC code. This temporary pair could have been simplified (as many online registration systems use 4 digit codes), but again, it's only initial pain. Once you're past the pain, it's a great thermostat, with a nice bright screen, handy features, and remote management. I'd have loved to see them combine features of the Lyric series, but at the end of the day I wouldn't have used those features anyway. I think most people will need to cross shop this with a Nest. Honestly, if all you want is to be able to yell "Alexa turn up the heat downstairs", then this does the trick, and stays stylish at that. If you have a regular weekly schedule and value behavior similar to your 10 year old Honeywell then this is your thermostat. However if you're really interested in geofencing, or fancy sensors figuring out if anyone is home, or budgeting/estimation tools build in this is not your thermostat. At the suggest MSRP I find some of the functionality lacking for the money, but it's hard to knock something that (once setup) works flawlessly.

    A NICE UPGRADE TO THE PREVIOUS MODEL

    I had the previous model of this Honeywell Thermostat, a green background with black text. This new model is a nice upgrade to that unit and I'll explain why in a moment. Please know that the upgrade path from that model to this model took only minutes, because the wiring issues were worked out last time and the labels/and inputs are the same, just in different spots. The screw holes are even in the same spot so re-mounting the new one in the old spot was super easy. As for what is nice on this upgrade, the silver looking bezel, color screen, humidity level inside, the temp and humidity outside, and the much easier sized touch screen area to work with. It is overall smaller, but the areas to touch are so much easier to select. Programming is such a nice improvement - programming is so easy on this new model. If you review the pictures, you'll see how much nicer the new unit looks, but also how it is easier to read. The older unit was nice, but the little print was hard to read. With these units, the online access is amazing, allowing you to change the temperature through the app or the web. You can also change the system from heat to cool, or from cool to heat, etc. The system can notify you if the temperature rises above or below certain thresholds, if humidity is too high or too low, or if the system loses contact with the monitoring center online. After years of already having a Honeywell smart thermostat, I found my heating/cooling bills were a less as I used scheduling to turn the heating/cooling up and down vs. doing it manually all the time. You can count on saving money, because you get used to a certain set of temperatures vs. when you set it manually, it is easy to turn it up alot or down alot as sort of an impulse change vs. a schedule. Reliability of this has been amazing, and the value is paid back in convience, if not in utility bills. A quick story comes to mind over this summer when the temperature in our house went to the point where I have a notification set for, and because of this timely alert, I was able to get my A/C service company out - it was a Friday at 3pm and they happened to have someone in the neighborhood - this timely alert saved me from sweating all weekend until service came out on Monday. If I had a wish list, it would be that the outside weather forecast, which can be viewed through preferences, would show on the screen as maybe an alternating screen to the current temperature settings. I would also make the backplate just a bit bigger, like the older model, to make it a tad easier to wire. However, the wires are much easier to install, because of the press in wire sockets vs. needing a screwdriver. You can also remove the wires by pressing in on them with a ballpoint pen tip....very nice touch. In settings, you can also provide an offset, if you find you are used to a slightly different temperature or humidity level, so the system can adjust using this offset, and display the temperature as you are used to it. I found the temperature and humidity seems to match the multiple temp and humidity sensors I have scattered around my house. Buy with confidence, this is well worth the money, and I remember from my last one I put in, their tech support was superb when trying to work out my specific wiring concerns (heat pump with emergency heat). I didn't need tech support this time, it was an easy upgrade path.

    Honeywell - Smart Color Thermostat with Wi-Fi Connectivity - Silver Honeywell has a nice Wi-Fi thermostat here but it feels incomplete. First off I do give Honeywell credit for making the install or in my case replacement fairly easy. When you read the install instructions it will say you must have a “C” wire. The “C” wire provides continuous power to the thermostat and is said to be required. Thankfully it also provides instructions in case you don’t have this “C” wire. I am no expert but my house was built in 2004 and it had an older programmable Honeywell thermostat. I did have the “C” wire and I suspect if your current thermostat does not need batteries and is digital that you probably also have this “C” wire. Once you remove the front of your existing thermostat it won’t take long before you know if you have the “C” wire or not. With my older thermostat I never really tried to program it on it’s small screen. I mostly ran it on a fixed temperature and would just move it up and down as needed. This version is easy to program both on the device itself, using the Android or IOS app or the desktop webpage. The same can be said for the simple WiFi connection to my home network. The instructions for how to wire were clear and Honeywell also provides quite a bit of online resources, videos and a toll free number. The only issue I had was the surprise I found when I removed the old thermostat. Behind I found a sloppy made hole for the wire bundle and once removed some of the drywall broke away making the wire hole bigger. That’s not Honeywell’s fault but if they had made their mounting backplate a little bigger or even added an optional backplate that was just a little bigger it would have made the install easier and simpler. If you do a search and watch a few online videos you can see this surprise appears to be common. The display color choices are very well done and I found an off white color that made the display very clear and easy to ready. I was very impressed with the color options that were available. The display is clear and gives you quite a bit of information that is very easy to read and understand. Everything is working well but I did have a few issues. One is the mobile app was a bit confusing. When you make a change it doesn’t really have any instructions on how to save your changes. The changes are saved but I had problems of the screen locking up and the only way I knew the changes were saved was when I came back to the screen after restarting the app. I didn’t have this problem with the PC website or on the device itself. This device can also be controlled by Google Home or your Amazon Alexa. Setting it up to my Google Home took all of five minutes and it works well. I just did a web search and found the instructions. The Honeywell support page has Alexa instructions but not for Google Home. Still it was very easy to setup. One final thing I am still puzzled about and that is the thermostat cannot automatically switch from the air conditioner to the heater. I could not find information that says that feature is supported and there are no settings that give you that as an option. Honeywell does say it has “Advanced fan/comfort control”, but the only options are always on, auto and circulate which they say “Fans runs randomly, about 35% of the time”. This is a nice device, it is easy to install, it does work with your smart home assistant and the display is very nice. But not having the ability to automatically switch from heating and cooling without me manually changing the system from heating to cooling is a feature that is lacking or at least poorly explained.

    Honeywell has built a stellar reputation for Energy Management, Security & Precision Temperature Control in Commercial Buildings & Homes. With the popularity of "Smart" Thermostats, many previously unheard of brands appeared. Unfortunately, independent testing found some of the most popular "Smart" Thermostats actually maintain 3 degree F accuracy! Model # RTH9585WF is a Generation 2 Honeywell Smart Thermostat, and like Gen 1, it is rated to maintain 1 degree F accuracy. Installation is as simple as following a video, or reading a PDF. If you can place colored wires under a screw, you can master this installation with ease! There is even a toll free help line. This thermostat features very large numbers that can be read across the room. Outside Temperature (sourced via the Internet using your Zip Code), Set Point & Actual Room Temperature are Boldly displayed. The background color behind the numerals is easily adjustable & can be set to match a theme / season / wall color / favorite team. The free App on iOS & Android is very easy to activate. Once the quick registration process is complete, you can monitor & change temperature anywhere in the world! Amazon Echo products & Google Home both work great with this Honeywell, and do not require an intermediary hub. This thermostat is designed for voice control from both "Alexa" & "OK Google"! One improvement I could recommend for a future Generation of this Honeywell would be the ability to purchase & connect Wireless Remote Sensors for temperature control of other rooms throughout the house. Another would be to integrate humidity control wirelessly. The run time on Central A/C has a dramatic effect on humidity, in addition to temperature. I owned the Honeywell "Perfect Climate Comfort Center Control System" with both of these features via hardwired sensors. They worked GREAT, but I wanted a Smart Wi-Fi Thermostat, so I naturally stayed with Honeywell. Measuring 0.75 x 4.5 x 3.5 in, this is a slim, bright, good looking precision instrument that earned my Highest Recommendation!
