Side by Side Comparison of: Honeywell

I wanted a WiFi controllable thermostat but didn't want to pay for the overpriced Nest and other similar units. I have an irregular schedule that I don't think Nest can perform its motion detection voodoo on so would prefer just to program my own schedule or turn it on and off when needed.The unit itself has a full set of physical button controls on the unit itself. I prefer this to the simplified touchscreen units so that non-techie members of my family can still control things. You can program the schedule, turn the unit to cool/heat/off, turn fan off/auto, set temperature hold and more directly on the unit, exactly like regular programmable thermostat units. Of course, in addition to that you have the WiFi controls that you can access via app and via web page. This is great so you don't have to get out of bed to turn the unit on/off or can set the house to warm up or cool down when you're on your way home to arrive at a comfortable home.Installation is simple...IF you have the blue "C" wire hooked up to provide power to the unit. The unit can't be powered by batteries like a regular thermostat because the wifi radio takes power to operate continuously. The C wire in your thermostat cable connects to the controller board in your furnace and provides a power source for the thermostat. My house didn't have the wire hooked up, but a quick trip up to the attic showed that the wires were there but not connected, so I connected them to the board and that worked to power the thermostat. If there aren't enough wires in your thermostat cable, you'll have to run a new cable or use a Venstar Add-a-Wire.The app interface is quite easy and you can easily control all the unit functions. My only complaint about the app interface is that the cool/heat/off setting is on a different screen than the temperature setting. This means that in most cases you have to go to the screen and turn it to cool/heat, submit that, then over to the temperature tab and set that to a lower/higher temp to kick the unit on. I'd prefer these were both on the same screen to make it a one step process. I also appreciate that there is a webpage interface so you can also access the controls when using a regular computer.Overall, I'm happy with this purchase and it does exactly what I expected.

I replaced the thermostat on my Houseboat with this WIFI model. I now have it connected to a cell phone on my ATT plan, which costs me about 1/2 the price of the local WIFI service at my marina. I just leave the phone on and plugged in at the boat, with the Mobile hotspot on. The thermostat does less than 1GB of data/month, so no fear of causing an overage on my plan. Now I can leave the thermostat set to like 85 degrees in the summer while we're not there but login to it remotely before we get to the boat and turn it down to a cool 72, so that it's really nice when we walk in. Same for the winter time, set it to keep the boat from freezing inside but remotely adjust it to 69 or so before we get there. LOVE IT!!!

Very basic but does the job I wanted it to do.The set up was very simple and straightforward. I had to move one of my wires to get power to the panel which is fine because now I don't have to worry about batteries, but I did lose the ability to independently turn on my fan, which isn't a loss for me.I don't really want my thermostat to "learn" about my habits because our household is always doing different things every day and I'll turn the temp up and down as needed. Now with that being said I would like to keep a history of how long my furnace or AC is running so I can see if it is running a lot when I'm not home or thorughout the night, etc.The mobile app for this is simple to use and you can manage the thermostat completely from the mobile app, which is what I do. I haven't touched the thermostat since it has been set up. I love the fact that if I know I'm not going to be home when the schedule is going to kick in then I can set the hold based on time, which is also cool. I can set the temperature and set it to either hold it permanently or have the hold go back to the schedule at a certain time.Excellent thermostat for what you get, could add some analytics to it that would be nice. I don't see the value in getting a thermostat that is more expensive than this, I don't care what it looks like.

Well, the reviews on the wiring were pretty straight up. I don't know a thing about electricity. I saw that I didn't have a C-wire, but thought I might get lucky, so I tried to hook it up ... no luck. If would flicker on and off. I tried to put the old thermostat back on, but even that didn't work!!So, I left to go to a game with my family at 11 am and did not get home until about 9 pm. House was 78 degrees and humid. No way I could sleep. I watched the videos on YouTube about how to use a G-wire as a C-wire. Still now luck. At about 11:30 pm, I gave up ... sweating like a maniac. My kid came downstairs to sleep b/c she said it was too hot upstairs. That inspired me to get back on the computer and get it figured out.Then it happened!About 6 or so minutes into the Honeywell video on YouTube about switching the G-wire to a C-wire, the narrator said, "don't forget to put the outside panel back on your furnace because it auto cuts the power when you take it off." I put it back on ... 5 seconds later, the air conditioner kicked on. It was a total, "wow, I could have had a V-8" moment. If I wasn't so ignorant about the basics of a furnace, it would have taken a grand total of 5 minutes to install if you just follow the Honeywell YouTube video step by step.For all the people griping, all I can say is "c'mon, compared to the $250 nest in the Apple Store, this thing is great."You get 60% off and it is not Black Friday or Cyber Monday.

I had looked at the Nest thermostat initially but then started reading the reviews on this one and took a chance. First of all the price was much more reasonable than the Nest and it has many of the same features. It has a large easy to read display and programming is very easy.Installation was very easy and even includes little labels to put on the existing wires so you know exactly where to hook them up to the new one.Set up was a little bit of trial and error, but no more difficult than setting up a wireless router. At one point when I got stuck I just needed to reset power and then my device connected no problem.I can connect with my laptop as well as through the app on my iPhone, which is an awesome feature. You can check the settings or adjust the schedule from anywhere.It also has a learning feature that adjusts the time it turns on to reach the set-point based on how efficient your HVAC unit works.One last thing to mention... I was getting very frustrated after the initial set-up as the time and day were incorrect and I couldn't get it to change on the thermostat. I went to the set-up page on my laptop and entered my timezone, this automatically updated the time and day. This operation was not explained anywhere in the manual or on the website.

I have now purchased 3 Thermostats installed them all myself in about 30 minutes (including programming them on the computer and smart phone). I can control the temperature via internet from anywhere.Be aware though that you need at "hot" wire (24 volt) to your current thermostat. If your thermostat currently runs on batteries, then most likely the hot wire is not connected. If there are extra wires run to your current thermostat, one of them may be hot. REMEMBER, turn off the power to the furnace when you connect the wires. 24 volts can sting hard and could blow your transformer in the furnace as well if the power is not turned off.

I thought I would write a limited review of the RET97E5D to describe the four challenges that I had installing two of these and how I resolved them. This review may be helpful for you under the following circumstances:1. You need to use a separate 24VAC transformer to power a Honeywell thermostat;2. You encounter the "ERROR,200" code when trying to link the thermostat to your home wifi signal;3. You need to call the Honeywell technical support number; and/or4. You are not able to register the thermostat at the Honeywell Total Comfort Connect website after setting up the wifi signal.Otherwise, you may as well skip this review, as these are the only subjects covered.I bought two of these units for a new-to-us, 115-year-old house. A year ago, I installed four RTH6500WF-series thermostats in a different house. As far as I can tell without undertaking a detailed comparison, the RTH6500WF and the RET97E5D units are visually and functionally the same. From a cost / functionality standpoint, I was quite happy with the RTH6500WF units so I decided to install the same or similar units in the new house.1. Power from plug-in transformer - The new thermostats are being used with a two-zone, heat-only system. The heating system in the new house has a baseboard zone controlled by a Taco controller board with a 24VAC common terminal. Although I needed to run new 3-conductor wire from the boiler to the thermostat, the terminal labeling on the TACO controller was very easy to read and it was easy to connect the red, white and common wires at both ends.The other zone is a steam zone with an older 24VAC Carlin controller that does not have a common terminal. I considered sharing the same common terminal on the Taco baseboard controller but lost my nerve, fearing that I might damage one or both controllers (Honestly, I don't think there would be damage, but I did not want to find out the hard way, especially at the start of heating season). To bring power to the steam zone thermostat, I ended up purchasing a 24VAC transformer on this same web site for about $12 and connected it to the thermostat through a separate feed. This is easy: just remove the pre-installed tiny "U"-shaped wire jumper between R and Rc on the thermostat's wall plate. The boiler controller's red wire attaches to R and the controller's white wire to W (i.e., standard 2-wire, heat-only configuration). To power the unit, the transformer's red (or positive) wire attaches to Rc and the transformer's common (or negative) wire to C.2. The next challenge I faced was connecting the units to my home wifi, and it was the frustration I had with this process - and the ultimately simple solution - that prompted me to write this review. Having activated and registered four similar units last year, I remembered it as an easy - if somewhat redundant - process (redundant when setting up four units, that is).However, this time around, when my laptop was still connected to the thermostat's temporary wifi signal (which is used in the first wifi set-up step to link the thermostat to the permanent home wifi signal), the process returned an error code. Note that the error code appeared on my laptop and not on the thermostat's LCD screen. According to the manual, some - or most - error messages will appear on the LCD, however, in this case, there was no error message. Rather, on the LCD, the thermostat remained in "Wi-Fi Setup" mode and did not switch over to the "Wait" message that would normally appear if the wifi linking process had gone correctly.The error message on the laptop was fairly cryptic: "Possible issue detected (ERROR,200)" My efforts to research the meaning of this error code in the supplied Honeywell manual or online were fruitless: I could not find a single reference to the meaning of the code.As suggested by a helpful Amazon shopper, I called the Honeywell help line using the number on the back of the thermostat (more on that in Sec. 3 below). I eventually got through to someone, and, after some preliminaries, I was able to pose the question that was the purpose of my call: Question: What is the meaning of error code 200? Answer: Error code 200 means unsupported web browser.I had been using Firefox to connect to the thermostat's temporary wifi signal. I was able to connect to the signal just fine, and to select my home wifi signal and enter my passcode. But then the linking process that this step triggered would fail and I would get the error code described above on my laptop screen. Based on what I was told by the Honeywell representative, I retried the process using the Chrome browser and the thermostat connected immediately to my home wifi.It seems to me that this error code ought to be described in the Honeywell manuals and/or on the Honeywell web site, as it could trip up a lot of customers. But as far as I could see, it is not.3. Calling the Honeywell technical support line was in itself not entirely free of glitches. The main one was that there was a long, silent gap between the initial audio greeting, which referenced an upcoming menu of choices and the playing of the menu itself. I would say the gap of dead air at was at least 2 minutes long and perhaps longer. I hung up the first time, thinking there was a problem with the phone connection. The second time I sat on the line and the menu choices were finally presented. Also, the audio quality of the call was atrocious.After making my menu choices, I was eventually connected with a nice woman in a faraway country. She seemed to think that I was calling because the Honeywell Total Comfort Connect website was down for maintenance on that day. This Total Comfort Connect web site is the Honeywell-hosted web interface that allows users to control Honeywell wifi-connected thermostats such as the RET97E5D and the RTH6500WF and thus is an essential part of the set up and ongoing use process for those who use the remote access features of these units.Prior to making the call, I did not know that the Total Comfort Connect website was not working. I would have discovered that in the next set-up step, of course, but since the thermostats were not yet connected to my home wifi signal, there was no way I could connect to them through the Honeywell site at that time. However, it was helpful to know. She assured me that it would be back up and running soon (which proved true).4. Registration proved to be the final hurdle. In order to have remote access to the thermostats it is necessary to register them on the Honeywell Total Comfort Connect website, which, like the wifi setup, should normally be a simple if redundant process. Since I had been told on the call that the Honeywell Total Comfort Connect website was down for repairs, I stopped what I was doing after having linked the thermostats to my home wifi signal, and returned to the process about 12 hours later. By that time, the Honeywell site was back up.Since I already had a user account for the four other Honeywell thermostats in the other house, I did not need to create an account. I merely needed to create a new "location" and register the two new units to that location.Registration involves typing in the MAC ID of the thermostat unit and a related 4-digit code, both of which are printed on the back of the thermostat, into the "new device" menu section of the Honeywell Total Comfort Connect website. I was able to do that, but when I pressed the "submit" button to activate the registration, the registration was rejected. No specific error code was given, but there was a generic statement to the effect that the thermostat's wifi connection might be down.The thermostat's LCD screen has a wifi icon that was showing a 4-bar (i.e., maximum) wifi signal, so I figured that the connection was fine. At this point, I was in a "I'll try anything to get it done" mode. I pulled the body of the thermostat off of the backing plate for a few moments, then re-installed it. This had the effect of cutting power briefly, but not long enough for it to lose its wifi and other settings. I returned to the Honeywell Total Comfort Connect interface, retyped the same MAC ID and 4-digit code, pressed "submit" and the registration was accepted.I don't know why this last step worked. It could be that some setting had timed-out in the approx. 12-hr. period between the wifi setup and the unit registration. In any event, just pulling the unit off its backing plate and re-installing it 30 seconds later was all that was needed to allow registration to proceed.These thermostats can require some effort connect and set up - and the instructions could be better and/or more complete in some respects - but overall I think the unit is good, especially for its price.

Pros: Easily programmed via website or app - Simple, easy to use physical interface - Ability to set up hot/cold alerts via email - Can schedule each day differently if need beCons: It makes a fairly loud clicking noise when activating the heat or AC - The app has a useless "Contractor" section which seems to exist solely to sell you on services - Requires C wire or workaroundOverall this is a great entry level WiFi thermostat. It gives you the ability to monitor and control your heat/ac from anywhere and offers a lot of scheduling options. Most people really don't require any more than this. Although the device doesn't natively support integration with other WiFi products, there is an IFTTT channel dedicated to it, allowing for many features available in higher end thermostats, like geofencing and temperature changes based on weather conditions.I do not have central air, so I only have a two wire setup with no C wire, and I panicked a little when I realized I couldn't power the thermostat. I wound up discovering that you can use a 12v AC adapter to power it. Running a wire from the thermostat to an outlet wasn't ideal, but it got the job done. The adapter I bought was meant to be plugged into a regular AC adapter port, so I had to cut the end off and strip the wires. I would love to see the option to power this with a battery or have it draw power through the two wire connection like the Nest, but I'm sure that would add to the price.The Honeywell app allows you to set schedules, adjust the temperature or turn the system on or off. There's also a useless contractor section that should be completely removed. The previous version of the app used to require you to press a login button every time, but they have recently updated it to bypass that if you save your login. I never use the website anymore, but that is where you would perform your initial setup, and the only place you can set hot/cold threshold alerts and add email addresses. Why they don't include this in the app is beyond me, but they also don't seem to put a lot of upkeep into the app, as it has had one update in the two years I've used it.The one annoyance I have with this, and every Honeywell digital thermostat I've owned in recent years is the audible click they make when activating the heat or AC. This was initially installed in my master bedroom, but the click kept waking me up, so I moved it out into the hallway. I still hear it, but with the door closed it doesn't wake me up. This is obviously a matter of preference, but there is no reason a digital thermostat should make any noise at all, let alone a loud clicking noise at all hours.

Basic installation (replacing the existing plate) was easy, although we did have to have our HVAC guy come adjust the settings, but if you have a good relationship with your HVAC company, they'll normally come out and do it real quick for free or a small service charge.Thermostat works well. We don't use the programming feature since it's a vacation home we rent, but the interface is easy to use albeit dated. Features are pretty standard, though, including being able to set up alerts for temperature spikes or drops, etc. Either way, it's a good deal for a no-frills WiFi thermostat.

I spend a lot of time out of town and wanted a WiFi thermostat such that I could control my power consumption while on the road. Prior to this device, I used a WiFi thermostat provided by my power company. That thermostat was inconsistent in how it worked. Sometimes fine, other times the control would show bad readings or inability to modify any settings remotely. For that and a number of other reasons, I decided to try this Honeywell model.I didn't install the thermostat. My power company did as part of removing their system from my house. I have installed other ones and know that this one is installed in a similar fashion and wouldn't expect the average homeowner to have much difficulty making the electrical connections provided you had a C-wire at least. Fortunately, mine did.I did set up the WiFi portion myself which went very smoothly.For the down side, when the power company's electrician left my house, the thermostat was not working. As I would later discover, he installed the wiring perfectly fine but he didn't go through setting up the modes in the thermostat and he didn't check the operation prior to leaving. This in itself was not the thermostat's fault and really only takes a few seconds but this is where I ran into an issue. Making the setting changes is very easy. Simply hold two buttons, follow the instructions in the user manual and you're done. Sounds easy but it's not...The real problem is apparently my lack of knowledge of heating/cooling systems. The manual tells you how to easily make the setting changes but doesn't explain how to tell what settings your system should be. Do you have a heat pump, individual heat/ac unit, electric or gas, does the heat pump work in mode A or B, etc... Frankly, I thought I knew the answers before trying to change the settings but I didn't. I even looked at the web site mentioned in the user guide and thought I found the answers but I'm wrong. I'm embarrassed to admit it but I ended up with settings that ran both my heat and cooling at the same time. My house would heat but very, very slowly and inefficiently. It took another trip back for the installer to make the proper settings.For the functionality and value of the system, I'd give it 5 stars. Wiring instructions (I didn't do this one but have done it before and read the instructions) and WiFi setup, again 5 stars. The rating loses 1 star only because of the knowledge needed about what type of system you have with lack of explanation on how to determine this.

I ordered this after considering Nest and several other makes. My major need was control via the internet, and I didn't want monthly fees. This unit fills the bill at reasonable cost, and the Honeywell name means something.BUT, installation presented a couple of challenges.First, the unit needs 24 volts AC power, which isn't available in my vintage system, so I had to install an external transformer and run a second wire to the unit. That turns out to be pretty simple (just connect the 24v to the C and one of the R terminals without removing the jumper), but you might not realize that from the documentation.Second, the unit assumes that the wires come through the wall. There is no provision for bringing in wires from the wall's surface, which is where mine are. After some frustration, I whittled away enough of the molded plastic with a breakaway knife to allow the wires an entrance.At this point, things become straightforward, although you need a very small flat-blade screwdriver to attach the wires. Once attached and powered up, the thermostat began immediately to work using its default program. The procedure for attaching the device to my local wifi network was clear and simple; it worked without drama.The next step is to set up an account with Honeywell (easily done) and get it activated (not quite so easy). The system is supposed to send an activation email to the address you provide, after which you can control the thermostat via the internet (remember, that was the whole point). I could not, however, get their system to send me the required activation message. After five tries over 16 hours I finally called the support line, and after only 1 pass-off and 4 interludes on hold the technician manually sent the elusive message. I logged into my new account, connected instantly to my device, and reviewed the program settings from my computer.I downloaded the tablet and phone apps, which are clean and elegant. It's much simpler to program the device from an app thanto use the on-board buttons. The apps allow you to access any part of the week at random, whereas the buttons force you to work through the days and times sequentially--which gets a little tedious.In the end the thermostat functions exactly as I had hoped. Aside from the lack of information on using an external 24vac supply, the documentation is very good, and tech support was courteous and helpful. I'll likely purchase at least one more of these.Update: I did purchase another one of these units and installed it the same way. Both are working perfectly, and the phone/tablet apps operate them quite smoothly. I'm quite happy with the system and may yet install a third unit.

Initially I thought of getting higher end Honeywell wifi thermostat RTH9580WF1005 but I could not justify the $220 price tag. The higher end thermostat has color touch screen and also displays the outdoor temperature and humidity whereas this unit does not. Color and touch screen may not be that important in thermostat as we do not need to look at it often once we program the schedule. So I chose this unit which costs little less than half the price of higher end unit.1. You can use the green wire as a substitute for C wire. You also need to switch the green wire to C terminal at your furnace. Honeywell made a nice youtube video on this. Good job Honeywell. Only disadvantage with this method is that you lose control over your fan. You can not manually turn on the fan, but it will turn on automatically when heating or ac is running. So not a big deal for many people.2. Connecting this unit to wifi is super easy. This unit creates a new local network to which you connect your laptop or smartphone. Once I connected my Ipad to this network, web browser automatically popped up with settings information. Chose your wifi network here and enter your network password.3. Register the device at Honeywell website for remote control.4. You can use web browser or free iphone, ipad or android app to program the schedule for different days.5. Iphone and ipad apps are excellent. They have simple interface and are fast.6. You can also choose to receive alerts to your email if some unusual things happen like power outage, your home temperature drops below some value, etc.This is my first Honeywell product and I am impressed with the company.Edit 1, 5 Dec 2013: The thermostat has been working fine. I really like the app. However, I wish I did little more research. I am thinking of returning this thermostat for the following reasons.1. This thermostat does not have any setting for adjusting temperature swing. I think no Honeywell thermostat has this feature. This thermostat tightly controls the temperature within +/-0.5 of set point. May be my furnace is over sized for my house. It cycles on and off too many times. Cycles-per-hour adjustment (CPH) has no effect at all; I set CPH to one and still the system runs around every 10 minutes. I think this will shorten the furnace life. I am knocking off one star for this.2. This is minor but annoying. The relay clicking is loud; easily heard from two rooms away.

I like the concept but could not use it because the power supply connector is mandatory, and it was not obvious to me fro the instructions so I ended up returning the product that I would have loved to use. I wish I could use a battery instead.

purchaed to help automate a new apartment without spending a lot. This model was 1 level a above what was already installed (added Wifi) and it installed and integrated wth Wink and Echo. if was easy to pop off the old one and install the new one. The UI of the thermonstat is not as nice as a Nest or Ecobee, but it does integration with Echo and Wink and is a good value espcially for someone renting.

I'm very handy, however after 3 days trying to make this thing work, I had to send it back. Get an electrician

Thermostat works fine, but Honeywell support is poor and inconsistent in their advice. Support needs better training.

Awesome!! Although I wish I didn't have to log on to a non-local website to adjust it from my pc or tablet. I'd like to connect to it directly on my local network. It's right across the room... :-(

We felt the instructions were incomplete, and we had to call the company to get it installed. Our heater is an "old school" gas heater with only two connectors instead of three. The thermostat works beautifully and I was finally able to connect it to the web site so I can monitor it online while away from home. I bought it for the alert function, but I wish it had text alerts as an option instead of just email alerts. Having whined appropriately about the lack of text alerts, I am sure I will be able to manage with the email alerts just fine.

lasted 2 months longer than the warranty

Makes my new HVAC system so much more enjoyable: Saves me money and allows me to be more comfortable as I can adjust the temperature shortly before arriving home and if I forget to turn it down, regardless of if I am away or at home already half asleep, I can just reach for my cell phone (great, simple and so far free android app--can't speak to iPhone operation), without getting up and adjust the temperature to anything I like. If you have a WiFi router in your home already, you will want to make sure to change it's IP address, BEFORE you program the thermostat, so as not to include 192.168.1.1, which is what this thermostat uses as its default. Am I worried about someone hacking into my system with malice? You bet! But so far I feel the benefits outweigh the risks.Update: This was once a five star review. Was doing very well for about eight months, then after a program update there is no way to login anymore. At first I couldn't login to my android app, then I could no longer login to my account and now, "next" button, which one needs to hold down for a few seconds simply does not respond, which makes it impossible to reset the thermostat repeat the setup. The 192.168.1.1 ip address under which it was registered on my network no longer loads. Granted the manual functions of the thermostat still work (ergo 2 stars) and it is still apparently communicating with my network, but that's not why I invested in a wifi thermostat. Have been in contact with honeywell and total comfort connect by email but so far, nobody has been able to do assist me It always takes several days until someone responds and then it is to ask things that have already been answered. I never touched the thermostat, never took it off its cradle, only used my phone and adroid app to manipulate it, even at home. My exact model number was TH6320WF. Warranty is non-existent.

The thermostat installed without a hitch and in and of itself, it is doing a good at keeping our house at the right temperatures. Even the Wi-Fi setup was a breeze and I could ping it from other devices within the house. So it is definitely online and shows up in my router mac address tables and all.After you get it connected to your Wi-Fi network, the thermostat displays this next step instruction: "Register at Total Connect". What this means is that in order for you to "remotely" manage your thermostat, you have to register it at this site: mytotalconnectcomfort.comNo big deal, right? Probably just like any other product registration where you don't have to register if you don't want to give out your personal information. Here's the rub: you cannot manage your thermostat for within your own house's Wi-Fi network. You have to make an account and password on that site and log into it to manage the thermostat. Why the concern? Read, as in really read, the User License Agreement (ULA). How a thermostat can be converted into a device that can intrude on your privacy like that leaves me flabbergasted.Because it is so intrusive within the boundaries of my own home from the Internet, I never agreed to the ULA and the Wi-Fi part of the thermostat is completely useless now.I should have just gotten the same thermostat features on a no-network thermostat. It probably would have cost me at least half the price. Lesson learned on wi-fi enabled home appliances. I will never take it for granted that I may not be able to manage it solely from within my home's wireless network. Using my own firewall rules, it would be a piece of cake for me to manage it when I am not at home without using some other Internet site's server with a personal privacy gathering capability that you must grant because you can't get passed the ULA to manage your thermostat without it. I won't even go into the details about the IT security implications it presents. This is bad enough.

Good:Unit was easy to connect (had a C-wire, so no issues there) and worked immediately. Instructions are clear, it was easy to set up for different HVAC types (such as heat pump), and connecting to WiFi was easy.Neutral:The box was missing the stickers to label the wires for installation, so I had to label them myself. Not a big deal, but annoying.Bad:First is the performance of the unit itself. Configured to run with the fan "on" (instead of "auto") - the system didn't cycle enough or as much as the previous thermostat to keep the house temperature even on different floors.Second is that programming the schedule is cumbersome at best - configuring 7 days, 2 modes (heat/cool temps), and 4 times per day means that I have to manually select and save 56 different numbers.Maybe the online system makes it easier, but I wouldn't know because of the third issue: the Honeywell Privacy Statement and End User License Agreement (which is mandatory for Wi-Fi access). This thing is truly scary - by accepting, you allow Honeywell (and third parties) access to an insane amount of information about you - GPS location, photos stored in the system, video or audio clips of activities in the home or business, arm/disarm or other usage schedules (to name a few). You also allow them to "use personally identifiable Usage Information" for many purposes. Don't just think of this as a thermometer, you're allowing them to use whatever device you access their apps and system with - computers, tablets, phones - I don't want them to have permission for any of this. This thermostat is being returned.

Straightforward design and simple mobile app, as expected. But the installation was a miserable experience (and I've installed many thermostats.) I was replacing a similar (non-wifi) Honeywell thermostat so it was easy to match-up where the wires went. But then I fired it up and 2 things happened. First, it just flashed A/C but wouldn't fire up. After getting wildly frustrated, I re-installed the old thermostat and it worked fine again. Turns out, there's a 5-6 minute safety delay after installing before anything works. After installing a 2nd time, I figured this out and it fired up. But then it started heating the house (while on the A/C setting). I called Honeywell support and they were just rude. First they kept insisting that the model # I was providing wasn't a real model #. (It was printed on both the box and the thermostat.) After the tech finally figured out which one it was, he had me work through a bunch of weird menu combinations (push the up arrow while pressing the run button!?). As it turns out, if you have a heat pump, you needed to go through this very complicated menu exercise that was covered on pages 51-55 of the 65-page(!) manual. The Honeywell technician acted as if I should have intuitively known this obscure point and was incredibly dismissive. I went with the Honeywell because this is a rental house and I needed the thermostat to be painfully simple to use (which it is). But in my main home I have 5 NEST thermostats which are a wildly superior product in almost every way. And the NEST thermostat support folks could not possibly have been nicer. I'll keep this thermostat but will never buy another Honeywell.

This was to replace a battery operated thermostat, and to utilize the WiFi function.1) Installation and wiring was easy.2) No way to connect to our WPA router. Web browser DOES NOT automatically open. The IP address given to access the configuration is the home network router page. Anyone that has accessed a WPA protected router knows that you have to enter the password to connect. No key pad on this thermostat, or manual connection through my router configuration.3) FEW features. Manual programming is painful. No "Weekday" or Weekend" configuration...day by day only. No filter monitor. No indicators if fan is running, or if system is active. No operation hours tracking.4) Our cheap battery powered thermostat has all these functions and is back on the wall. This thing is going back.

does everything a good programmable thermostat should do, AND it's wifi! first unit i bought made an extremely loud snapping (intermittent) noise when turning on, returned it and got a replacement through honeywell that so far is working good

Admittedly, the user interface, setup and installation were pretty straight forward. It's just a basic thermostat with a schedule and wifi remote capabilities.The problem is, this thing is constantly short cycling the heat or AC. I've counted it coming on for 5 minutes, shutting off for 5 minutes, coming on for 5 minutes, over and over. This will kill your HVAC system by wearing it out. Also every time the AC starts up it pulls massive power, until it gets going. There is no way to adjust this on the thermostat.This thing is junk. I had it for about a year and i just ripped it out of the wall and installed my older thermostat for now. Until I find a model with WIFI that isnt cycling so often.

Honeywell does not support this model for retail sales. I called Honeywell "support", which was anything but. Very rude and unprofessional. They definitely are not "technical" at all either. The first time I called Latoya told me that they do not support this model and I need to call the contractor. The problem was that no schedule ever loaded on the website. I could control everything just could not load a schedule. I don't think the contractors know anything about the software in the unit and the website user interface to troubleshoot this. I would think that Honeywell would. Apparently not. We have 2 other thermostats of the retail models installed(RTH models) and they work fine with the website.I called back a few minutes later and guess what, got Laytoya again. She put me on hold and never came back. Called a third time, this time I pressed the prompt for Contractors. Guess who answered again, Latoya. I asked for a supervisor. She told me they do not have a supervisor available. I asked when will they be in so I can call back. She would not say. Great customer support for your product Honeywell, NEST is going to put you to shame.

I could not get the 1st unit to work. Honeywell support suggested I replace it. The 2nd unit had the same no power problem. Honeywell no-support offered no other options but to replace the unit again. While the write-up says compatible with most systems, a list of the compatible or non-compatible systems would help. Since this unit is for a recreational property, I have wasted way too much timed on this to purchase another Honeywell product.

I emailed and called Honeywell Tech support a few times. Never a return email, never got any answers when I called. The tech support guy I reached by phone actually told me this model does not support internet connectivity. I read the applicable page in the product manual and he said the manual was wrong. He even asked me to send him a copy of the page out of the manual I was quoting and he would get back with an answer. I did that but never heard back. So, I don't know if this unit meets my needs or not. I can assure you tech support doesn't!!!

Ordered one for the ease of installation and configuration (up to which it lived, I will admit).However, after a week of use in very cold weather, I recalled why I had thrown several previous honeywell programmable thermostats in the trash in the past. CPH - cycles per hourHoneywell insists this is the "smart" way to control the furnace for maximum comfort rather than the traditional temperature differential method (1-2 degrees programmable difference before heat/air comes on). In my experience, in two separate houses with two different honeywell models (AC/gas units), this means constant short cycling. This is very bad for the lifetime of the unit, for it's economy, and, with forced air heat, comfort (in the form of noise). No matter what CPH setting I configured, the thing would come on constantly for a very short amount of time. If this is such a superior way to control temperature, give me the option to try the simple differential method and pick which one makes ME, the customer, more comfortable.On top of this longstanding honeywell design issue, it began to be unable to properly measure the ambient temperature after about 2 weeks of operation (more than 2 degrees off from the old thermostat which I kept as a reference).Replaced it with a radio thermostat CT30 and could't be happier. Programmable delta in 0.5 degree increments, better software, more reliable installation method (no "push pins" to lose contact). Oh, and a few bucks cheaper. Save your $$ and stay away from any of the honeywell programmable units.
