Side by Side Comparison of: Radio Thermostat Company of America vs Honeywell

Mounting the thermostat was easy, the top and bottom pop off to allow easy access to the screw mounting holes and batteries.The on screen interface more or less easy to use, but honestly I almost never actually touch the physical thermostat as explained below.Setup of the WiFi connection was relatively painless, but it does require connecting to the thermostat directly with a WiFi enabled device to select the correct WiFi access point and enter the password. I have never had any issues with the thermostat dropping the connection or not receiving commands.I selected this particular model because in addition to the official mobile app (which I have not used personally) it also offers a REST API that can accessed directly on the device without a connection to the public Internet. In short, this allowed me to write a small web page that runs on a Raspberry Pi computer and I can access from my phone or computer to control the thermostat. They did a good job designing an easy to use API for programmers and the DIY minded, and I'm pleased that because it does not rely on a third-party "cloud" server, I never have to worry about a service out of my control getting hacked or shutdown after a period of time.Overall, I would recommend this thermostat to anyone who is interested in do-it-yourself home automation.

I gave this all 5 stars because it is working well after being installed. I did have a problem installing apparently because Windows 10 will not connect to the thermostat for setup. I think this is because Windows 10 does not support ad-hoc WiFi connections like some older versions of Windows would have. To get setup to work I had to connect to the thermostat's WiFi from my iPhone, then switch my iPhone's WiFi connection back to my home network when the setup completed. All is well after doing that. The thermostat is doing a good job of regulating temperature and the Internet features are working nicely. It's nice to have a home thermostat that I can control from my smartphone.

We have a vacation home and this is the best purchase I have made. Really easy to install and gives you piece of mind, as it monitors temperature and will send an alert if it drops below XX. Best thing is it controlled from your smartphone so you can raise the temp when you leave and by the time you get there its toasty warm. This is the second one I have purchased, the first one stopped working (not sure why)

Great thermostat -- I got it to implement the geofencing (or Radius) feature but liked the fact that I could just copy the program from my old thermostat rather than hoping it would learn to do what I wanted.Wifi is difficult to connect with Windows newer than XP due to the way Windows identifies networks. The company recommends an iPad or Mac and does not support Windows 8.1 or Android phones. After some frustration in an unsuccessful attempt to follow the Windows directions, I used a Linux LiveCD and got it connected in under 2 minutes.It does need a C wire to run the wifi. You can use a transformer to supply the 24V for the wifi. However, I discovered that the Ecom 2 terminal on the oil primary controller on the furnace works as a terminal for a C wire, so I did not have to add a transformer.

I have two of these, 100 miles apart, and 200 miles from where I usually live.One is in a group ski club rental.Installed for 4 months now, and I frequently check them via internet. Always connect great - they are very good at keeping(or re-establishing if local connection is dropped) connected - never have not been able to connect.Ipad app is great for controlling/setting the programmed temps. Iphone app is great for both checking the setting, and also for turnng the furnaceup an hour before we arrive.I really like the history on usage. It is great. Nest and other "high end" thermostats can't do usage/runtime history but this unit can and it works great.It also can save big $$$ if someone at the group ski rental leaves the furnace on a high temp when unoccupied - I can easily turn it down remotely.

It's a fairly basic programmable thermostat, with wi-fi. During setup, you register it with my.radiothermostat.com, which allows you to use the web interface or mobile apps to configure/program/change current settings on your thermostat. The operation appears to be that the thermostat unit keeps the program internally. Thus, if you lose your internet connection, the thermostat will continue to do whatever it was programmed to. The benefit of having it internet-connected is (1) so you can change the temperature when you're away, (2) because it's more intuitive to set programs in a web browser than on the actual thermostat (though you can do it there too), and (3) it shows you usage logs of when your heat / AC were in operation throughout the day.The unit itself is of good quality, though nothing spectacular. The touch screen works fine, though I'd have preferred actual buttons. I preferred the way my previous thermostat mounted -- one piece screwed into the wall, and connected to the wires, and then the actual unit snapped on to that. This one is basically one piece, that screws into the wall. The wires connect at the top, with a small removable plastic panel to cover them from view.The real reason I chose this is because of the API. You can connect directly to the thermostat via the API whether you've registered with my.radiothermostat.com or not. API commands are issued directly to the thermostat's IP, and it's all simple JSON messages. The only disappointment is that there's no authentication, so you probably won't want to expose it publicly.Like just about all wi-fi thermostats, you'll need to have a "C" wire for power. I didn't, so I used the trick of jumpering my "G" (fan) to "Y" at the furnace, and then using the wire that previously connected "G" to the thermostat to instead connect "C". This means I can no longer control my fan independently -- it's on when the furnace/ac is on, and off otherwise.

I wanted to review this to hopefully illustrate why this worked for me. This is not internet dependent like those other big brands. That is a big deal. If this cloud service goes out I cannot access it from outside my home network. But this was one of the very few brands that allow wifi only access. Imagine you get a device that depends on the company's cloud service and if it disconnects you can't access your device at home. That's nonsense. The cloud is not the only way I would need to access it. The device is simple no frills by the way so that sucks. Interface via android works but you have to press several times for it to catch you syncing. Its basic and works but offline (internet) access is what I needed.

Works well now but installing it was a pain. Guide not well written. My problem was only solved by calling tech support. Solution was to unplug internet module and re plug it in. It must have come loose in shipping. App is easy to use and well thought out. I bought a second unit for our main house. The concept is very useful for us.

This was a replacement of an Intwine thermostat for my vacation home. This thermostat is used to adjust the heat and AC while we are away and to prepare for arrival. The prior Intwine model is apparently a private label of an earlier RT model. While the prior thermostat worked fine, the remote access from Intwine was terrible with multiple outages and zero customer service. I elected to replace with this model directly from the supplier RT. The new thermostat works perfectly and the RT remote control website and app is outstanding.I would have given 5 stars, but the RT customer support was not up to the quality of the thermostat. My install site is an evolution of several heating systems and wiring. RT customer support were not very helpful with the complexity of a separate transformer and the heater wiring. While it is mentioned in the install manual, it was not helpful and they were not either. It took a service call with my HVAC supplier to figure it out in an hour. RT customer service said it was the HVAC. Turns out it was the instructions from RT.That said, Intwine and RT should rescue the apparently few remaining Intwine users with a program to migrate them over to the RT website and app.All in all - an excellent piece of equipment and I highly recommend.

As others have said, this device is difficult to program. It's easiest to just install the app, hook the thermostat to your wifi, and program it with your phone. The touchscreen of the device leaves a lot to be desired; you have to press a couple times, most of the time, to make a selection, and the menus are a bit confusingInstallation was easy enough, and connecting it to the wifi was fairly straightforwardOne thing I really don't like is that the Radius feature, which is why we chose this device over similar ones that didn't cost as much, requires that the app be actively running on every device it's installed on, or it won't work. It's not enough to have it installed, it has to be running. Basically, you have to choose between saving on heat and saving your cell phone battery.Overall, it's good once you get used to it; it's really nice to be able to change your heat settings when you aren't home or aren't near it, but you almost need to use the app for most features on the thermostat. It's too complicated not to.

It's no NEST, but it will control a millivolt system (simple gas or propane furnace that operates without outside power). I have that in a pair of vacation cabins. I installed the CT50 in one, and after a few weeks of shakedown, installed the second. Looks like they reduced my heating bill substantially--perhaps enough to pay for themselves the first year. These are mountain cabins and if nothing else, these thermostats will hold the temperature just above freezing, 10-15 degrees colder than the manual ones they replaced. After the second installation, both thermostats show up on the Radio Thermostat app on all family iPhones, where they can be easily monitored, adjusted and programmed. Since these are vacation cabins, the "Away" setting is much appreciated. Same functionality, different interface is on the website. Indeed, it's far, far easier to control these with an app because the panel on the thermostat itself is hard to read and hard to use.Setup is not plug-and-play. While the box includes hardware installation instructions (and that part is very easy), the networking instructions are online only. Those steps are complicated enough that I recommend you set aside at least an hour for programming.And, since I mentioned the millivolt capacity, rare among WiFi thermostats: If you have a millivolt system (or no "C-wire") you'll have to buy a separate A/C power supply (about $20) and wire it in. WiFi won't run on batteries alone. A bad power supply was my biggest initial obstacle. Fortunately, their customer support is very good, and a tech quickly helped me troubleshoot the problem.I could've gone with NEST, but would have needed an electrician to rewire the system to a higher voltage. This works fine.

It works great. The app is useful and makes programming it easy. It's somewhat non-intuitive to program without the app. It was also a little tricky to setup. I misrembered my wifi password. It failed to set up without giving me a clue why.On nice feature of the app is that it keeps track of when your heater has run. It also graphs the tempersture. The only problem is that the temperature range is fixed and doesn't go low enough for my minimum temperature. I'm using it to control the heat in a workshop. I allow the temperature to go to 45 at night just to keep the pipes from freezing. It is also handy that you can override the setting remotely and prevent the heater from coming on. I didn't use the shop today, so I didn't need to heat it above the minimum.I am using it just as an on/off control for a heater. It can control an air conditioning unit as well. All in all I find it to be a useful gadget for my application.

This thermostat has one fatal flaw...why have a smart thermostat if you can't control it remotely and locally both? This thermostat allows one or the other but not both! I confirmed with the manufacturer that if I turn on the Z-wave control I can no longer modify the programming locally...UGLY.

I've owned one of these for several years. I'm so frustrated that I'm taking the time to write this review. YOU'D BETTER HAVE APPLE PRODUCTS!!! They snub Android and now I find it doesn't / can't work with Windows 10. No development apparently for anything past Windows 7. Configuring WiFi is a real pain even with Windows 7 or below. What should be simple is outrageously difficult. This thing should self configure by using DHCP. How hard could that be? Instead configuration requires that it set up its own Wireless Access Point and is only usable by Windows < 8 or Apple Products. If you have Android or Anything more modern than Windows 7 good luck! Let me know if anyone can configure this for WiFi by using Windows 10. You then need to connect to its configuration network and setup the actual WiFi setting that you want. There is NO WAY TO DO THIS ON THE THERMOSTAT ITSELF which is RIDICULOUS for such a sophisticated little device with touchscreen. Once configured (assuming you can get past that hurdle) it will work pretty well until some kind of glitch scrambles the WiFi settings at which point you'll need to re-embark on the highly frustrating and arduous process of re configuring WiFi all over again. Another thing is that if the temperature is in the automatic mode (Hot / Cool to a temperature range), One cannot perform a temporary override. One must set it to Cool or Heat and take it out of automatic mode first. Another issue is the time it takes to sync with the cloud. What I do like (hence > 1 star) is the History that it provides concerning run time and also temperature setup. Another downside is that I've noticed that temperature must be at least a few degrees outside of tolerance before it will activate heating or cooling. So the range of variance ends up being larger than what one specifies. I really wanted to like this product. I spent a lot for it. So close to greatness but just misses it on configuration and tolerance. I look forward to replacing it as soon as I have the chance. Perhaps with something that works with all WiFi products and not just Apple. And perhaps one that can anticipate time to ramp up or down to a temperature. -- Another FYI: It DOES have an Android App. But this can only be used to control the temperature. It DOES NOT allow for configuration of WiFi which needs to be done with Windows < 8 or Apples Products.

While I like the concept of this programmable thermostat a lot, I am going to downgrade it to two stars for a couple of reasons. First let me say I own 2 of these and have had similar experiences with both of them. And second, I am speaking as a professional software engineer who knows a LOT about how to design good user interfaces. First of all, the touch screen on the unit itself is very problematic. Many times when I go to touch a control icon it does not respond. Trying to change the temperature up or down requires many touches of the up or down arrow before it responds. Much of the interface is non-intuitive and indicates there was a lack of use case studies, with real users, before the layout of the controls and menus were designed. Same thing can be said about the app that goes with my Android phone. There is no clear way to discover how to navigate around and get to the various setups and menus. I have two thermostats for example, and though I know it is possible and have done so, I still have a great deal of difficulty just figuring out how to switch between the controls to interact with either one or the other. Much of the user interface is simply NON-INTUITIVE! Third, many of the links and features of the app are actually broken and do not work. Try to send the company feedback for example, they do provide a "link" but it is useless. In the 2 years that I have owned these, I have not seen any updates or notification that a new version of firmware is available. That strongly indicates that this company simply does not care about it's customer experiences with their product and is making no effort to ensure that it is a high quality device. So overall I would have to say my user experience with this device has been extremely poor. On the plus side, once you do manage to get it set up and working, then it seems to work fairly reliably, so I am giving it 2 stars, because it at least does work...

Good thermostat once installed. NOT USER FRIENDLY IN THE LEAST TO INSTALL!!!!! Im an engineer with a masters degree. Short of enilating this unit i called customer service twice. Each time I was treated as if it was a major imposition tohave too speak with me. Two different representatives. After a half hour the unit worked well. Using it with vera edge was effortless and i like the unit now that its installed. I would not ever inconvenience the company again with any additional purchases however.

This is the first of two Radio Thermostats I've purchased, the second being the CT80. Both are fantastic at what they do when they're working but you definitely get more value out of the CT80 than you do with the CT50. First, here are a few things they're both good at:- WiFi control: It's a glorious thing to be able to turn on your A/C or Heat from work if you know you're getting home early or to set your thermostat to "away" from the airport if you forgot to do it before leaving for a trip. This translates into dollars saved by not conditioning an unoccupied house. The initial setup can be daunting but once it's up and running, using this via WiFi is a breeze. If you have the App (I use Android) and you're hooked into the same WiFi network as the thermostat, you can communicate directly with the unit for near-instant changes. This is magic on cold mornings that you wake up early and want to warm the house before experiencing the world... The only times I've ever had problems are when my WiFi network goes down at no fault to the unit. It'll continue with whatever program it was running with so it's not that big of a deal- Web analytics: Using their website, you can track when your thermostat turns on and see what your usage habits are. If you're a nerd like me, you can download months of data to an excel file and crunch numbers for whatever purpose you want, hoo-ray! If you're only moderately nerdy, you'll still enjoy the visually appealing and understandable graphs that the website provides showing your usage statistics and how you rank in efficiency compared to other house around you- Program customization: You get to set 4 temperature changes for every day of the week rather than a "weekday" and "weekend" schedule. Also, the App is VERY intuitive and perhaps easier to use than the website. It's well designed for touchscreen control****There are several things that the CT80 has going for it over the CT50:- Buttons! The touchscreen on the CT50 is a pain in the ass. Thankfully, I rarely used it but it's WAY easier using the actual buttons on the CT80 to change temperature. I literally used to pull out my phone while standing eye-to-screen with the CT50 rather than have to deal with touching it...- Circulation: To my knowledge, the CT50 does NOT have a "circulate" option. With the CT80, you can turn on "circulate" and it will activate just your HVAC fan about once per hour. This comes in handy if you want to try and keep the house a uniform temperature or, during seasons where the HVAC is rarely used, to keep rooms from getting musky.- Way more options: The CT80 seems to be able to control just about everything in the house. I'm a little worried it'll go sentient and suck all the air out of the house while we sleep. But seriously, it can control active ducts, multiple heat pump stages and other "auxiliary" unmentioned things in case you find an unusual need to expand. It's actually more than I need but it's nice to know I have this capability if the desire arises.- And even more options: The CT80 allows you to set how big of a difference the temperature should be before initiating a heating or cooling cycle, unlike the CT50 that is defaulted to 1 degree and cannot be changed (to my knowledge). If you want to decrease the number of daily cycles of your HVAC system (thereby extending the life of your equipment), this can be a very useful feature!*****There are a few things they're both poor at:- Wiring: Make sure you've got some tiny needle nosed pliers and a lot patience. Both units inevitably hide wires quite well if done correctly but "correct" means snaking itty bitty wires through itty bitty slots without breaking them... I almost gave up and just let the CT80 dangle from the wall- Unit mounting: Make sure you've got a skinny phillips head screw driver and don't forget to limber up your wrist before using it here. The screws used to mount these units to the wall are about 2 or 2.5 inches long and must be slipped into a hole just wide enough to fit the screw. Once mounted, these things are sturdy but getting there, especially after having to wire it, will test your nerves.- WiFi setup: The CT80 seems to have gotten a bit easier to setup but this is a review for the CT50, isn't it? FAIL. It was a device designed for use with iOS devices and IS NOT SUPPORTED on Windows 10 computers or Android. AFTER its setup, you can control it with a web based application or with an android app... good luck getting it to that point.I used to recommend this brand but the WiFi setup has pushed my patience too far. Do not buy the CT50 if you're looking for an easy wireless thermostat

(See update at bottom!)I work for an automation company, and have been automating my home a little at a time. I thought about making my own thermostat, but the CT50 changed my mind. By itself, it's a fairly easy-to-use programmable thermostat, but in back, it has not one, but TWO slots where wireless cards can be plugged in. It comes with a Radio Thermostats of America Wifi module already plugged in, with room for another module; there are a number of modules available, (Zigbee, for instance). Here's the score, (IMHO):Cons:First, as noted by several other reviewers, the wifi requires a strong signal. Even a 10-foot increase in the distance between my Airport Extreme and the thermostat resulted in a significant drop in signal strength. Worse, if the connection is lost for any reason, the CT50 almost never reconnects, requiring a complete reconfiguration as though you had just installed it. I don’t understand why that is, when even a cheap $40 tablet is smart enough to automatically reconnect to a network it recognizes, and I chopped off a star for that utterly mystifying shortcoming. Even a tiny power glitch to my router would cause the connection to drop; I solved that by putting the router on an UPS, but that shouldn’t be necessary!Second, the touch screen isn’t the greatest; sometimes you really have to crunch it to get a response, while other times, I was able to accidentally trigger an item on the screen.Third, the manual is not always accurate. In some cases, the screens shown are somewhat different from those on the thermostat; in another case, the manual says when you want the Program screen, “Press PROG for to access it.[sic]” The picture they show, however, is of the Manual screen; it took me a while to find where the pictured screen was actually located.Fourth, it has a filter reminder, complete with a little red LED that lights up, but the reminder seems to be nothing but a dumb timer that triggers after a pre-set number of days or hours have passed, regardless of whether the fan has been off or has been running 24 hours a day. My previous thermostat had a timer that kept a total of the hours the fan had actually run, and reminded you accordingly; I had to roll my own timer to get this seemingly obvious functionality.Pros:Now for the good. First, I don’t even know how difficult the thermostat is to set up on-screen, because I used the recommended method of connecting my iPad to the thermostat’s built-in Wifi network and using a browser to configure it. It’s quite simple, and uses a 5-digit security code, displayed on the thermostat, that you must enter before it will connect to your network; this is a simple but effective way to prevent an outsider from hijacking your thermostat. When configuration is successfully completed, you’ll see a blinking green LED and hear three beeps, at which time the thermostat displays the last “quad” of its address on your network so you know how to access it, (most home networks use an address scheme like 192.168.1.xx, where the “xx” is a number from 0 to 255; each value is a “quad”, so if the thermostat shows “22", its address is 192.168.1.22).Second, you have four time zones per day, times seven days, each with its own start time and temperature, with separate setting for heating and cooling. You also have “Hold” and “Holiday” for those out-of-the-ordinary days.Third, it is cloud-capable, but not cloud-dependent, so you don’t have to worry about it becoming a brick if the cloud site is ever gone.Fourth, (geek alert!), it has a REST interface, with a very well-documented API so you can program it with JSON strings...which is what I’m doing, via an automation controller. It is sooo flexible! I have screens to read it, program it, turn it on and off...anything I can do from home, I can do from anywhere I have internet access, even from my smart phone. In other words, the future I heard about while growing up is finally here.Summary (with update):This device definitely has some quirks, and has room for improvement, but for me, those were at first offset by its capabilities and price. After months of living with its constant disconnects, however, I've changed my mind. It's not worth the hassle, and I can't recommend buying it, unless you happen to have a wireless g router just for this device.Update (06-15-2016):This is a bit sad. The thermostat has so much going for it, but the radio module has absolutely gotten under my skin. After countless disconnects from my very capable WiFi network, I have grown weary of its quirks, and have started replying to all of the "Your thermostat is offline!" emails I get as a result, (and there are plenty of them). I heard back from the radio module manufacturer, who basically gave me instructions to turn off any feature of my router that involved any improvement made to Wifi in the past decade, setting its capabilities back to about 2005. To me, this is absolutely unacceptable. Why should I have to cripple my wireless to accommodate a single device that itself should have been updated years ago, especially when it costs the same as a modern device does? I hate to say it, because I loved this thermostat's capabilities, but the radio module is an absolute deal killer. I'm leaving two stars for its promising design, but deducting 3 stars for its unforgivable outdated radio module. I can only hope that some day there will be a radio module worthy of the thermostat.

Research this carefully! I bought the first over two years ago and after a struggle with a bad radio module got it working despite poor technical support, this has worked fine since. I bought a second last November and once again after a struggle getting it set up it worked fine. My gmail account was compromised last week and I started changing all passwords, the Filtrete site was one of them.I changed the password online but afterwards could not log in. I requested a password reset but the email I received said the reset failed because the email address they had just sent an email to did not exist in the system. A phone call to customer support tells me I must now pay for support as the product, and apparently web site support are discontinued.The only reason I bought these were to control them remotely but I assume that is no longer, these look cool but apparently no more functional than a $20 generic thermostat from the hardware store if I can't get a hint on how to "reconnect" to the Filtrete "cloud". 3M needs to stick with paint and tape and leave the new fangled internet stuff to someone else.

This is the 2nd CT32 that I ordered - both are missing the z wave module. Returning again

Nearly impossible to set up and development is dead. I wish I would have read the comments section a little bit more. Could not connect with windows 10 pc or an android phone on marshmallow or an android tablet with jelly bean. In fact the thermostat wouldn't even show up.

Terrible/abbismal product support. Aparent firmware upgrade killing the WiFi, no answers over email, phone calls hanging up after 20min on hold.

No warranty. I have 3 in my house, 2 have failed and had to be replaced.Good luck getting a warranty replacement, there is none. Yes they are cheap for Wifi, but they are expensive when you have to replace every 18 months.Experience...I've owned 5 of them, so quite a bit.

All my comments are "allegedly". SEE UPDATES BELOW 1/2015When these were Filtrete, they were amazing, now it appears they are junk!!!Let me preface my review by saying I've been in real estate rehab/investing and do 99% of my own remodeling work for over 30 years. We first installed a Filtrete version of this thermostat probably five years ago and it worked flawlessly until a power spike took out the outdoor unit and stat. We've put these in our primary and vacation homes to keep track of things and manage the HVAC.THE HUGE New problems with this CT50:- In less than a year, we installed two of these in a new home. One is less than responsive with the touch panel, the other stopped responding with the touch panel and had to be replaced. The HVAC units are one heat pump and one AC unit with electric heat.- Before the Filtrete version was ruined, all the sudden the online/app name we gave the thermostat changed - to Spanish - on its own!!! It was if someone else perhaps got the IP/stat address.- 12/10/14 we went to our vacation home where the Filtrete died and replace it with a new CT50e which is what was sent when I ordered a CT50 from Amazon as the seller. It worked manually, got it linked up, programmed and all was well. Until we left for ten days.THE VERY, VERY BAD !!!!!!(Using iOS 8.1.2 and the latest 4.0 Radio Stat/Energy Hub app)- We went on vacation, nowhere near either home where these stats are installed (two in one home, one in the other). We set them all on "HOLD" 55 HEAT to prevent any freezing. Then they started to all act crazy.- All of the sudden they would change status. I can't even begin to explain the changes. They would go from heat to cooling - like change to "COOL 64". They would do this independently. Once I checked and they were all set different, one heat high, one cool low, all kinds of crazy stuff. This happened almost every day so i would have to check and change them all constantly.- I contacted Radio Stat tech support and had to be called back since they were so busy. The agent had never heard of the issue, looked through my history (the code logs) and deferred the case to Energy Hub. I guess they do all their app development. Got an email back saying basically they could not resolve the issue.- I tried resetting the app schedules, changing them from "HOLD" to a 50 degree "AWAY" setting and they would still change on their own. Mostly in the early AM after midnight. The "RUNTIME" feature indicated that the units did in fact change and run for extended periods of time. I can't imagine what our power bills will be when we should have been saving tremendous amounts of energy.- THEN THE WORST HAPPENED. I checked the home with one stat and it HAD CHANGED ON ITS OWN and was set to 98 degrees "HEAT" and the app indicated it was 89 degrees in that home inside!!!! We have just returned to that home and the heat pump compressor will not work and the supplemental heat (strips) and fan are all that come on. We replaced the CT50e back to the original Carrier stat with the same results.I FEAR THIS STAT MIGHT HAVE DESTROYED OUR $9,000.00 UNIT.THE GOOD of the CT50- None.This is another example of an excellent product gone bad. This used to be an amazing product that all I told envied - and a lot purchased. I guess I'll have to switch over to the Honeywell.I'll confirm what the HVAC a people determine in a few days. I'll update this review with our findings.UPDATE 12/30/2014- The HVAC installer has confirmed that when the thermostat switched to "heat" and 98 degrees on its own, it destroyed our HVAC compressor from over use (heat pump).- The "usage logs" confirm the ALL of the stats I own (2 homes) have set themselves to heat/cold to extreme temperatures on multiple occasions by themselves. I have the screen shots to confirm this.- I have to install a new package unit HVAC/Heat Pump now at $7,900. They will use the new Carrier "top to the line" IP stat.UPDATE 1/13/2015- The two remaining stats (one home, two units) were working "BETTER" for a while and not resetting. Monday A.M. at 12:01-ish as usual they reset themselves. I found this out waking up freezing. Checked my iPad by the bed and BOTH stats set THEMSELVES sometime after midnight to "36 degrees - COOL" on their own and it was 54 degrees inside (had been 70).- Finally took them offline today by pressing "Menu" and the function under the radio antenna icon to unlink them from my router to not destroy my two other HVAC units- Will be following up with Radio Thermostat, the BBB and two state Attorney Generals.JUNK, JUNK DO NOT DO IT!!!!!!!!!
