Customer Questions & Answers

will honeywell model Model # TH8320ZW work for model TH8320U1008

Asked by: Anonymous
They are almost identical, but the one with the Z on the end of the model number means it works with z-wave technology, which is very handy if you like automation. the model TH8320U1008 is basically the same thing without z-wave.

Nexia Home

Will this thermostat work with Nexia Home system?
Asked by: drKAT
Yes, absolutely! One of the really great things about Z-wave is that any Z-wave certified device should (in theory) work with any Z-wave controller, such as Nexia.

Does this work with the VeraLite z-wave controller by micasa verde?

Asked by: FollyBeachCondoRental
In theory, any Z-wave certified device will work with any Z-wave controller...browsing through the various home automation forums largely confirms broad compatibility across various devices & controllers. There are occasional hiccups or cases where only a subset of device features may be accessible through a given controller, so it's worth a quick Google search to learn what others are experiencing with setups similar to yours. In general, I would say that you should not expect to have any major terms of z-wave thermostats, Honeywell seems to be the reference standard from what I can tell.

Will I be able to lock-in the temperature settings so my kids can't change them?

Asked by: Anonymous
Yes, there is a 'screen lock' advanced function (accessible via System Setup) that includes 2 options: 1) all keys are locked except temp controls & Cancel key, or 2) screen is fully locked.

I did have some issues with the install, but to no fault of the design of the T-stat. I was able to install quickly with the existing wiring from the old thermostat. I would definitely suggest turning off the power before uninstalling the old T-Stat and installing the new one. I ended up blowing a fuse in my furnace (in the attic in the summer.) That took some troubleshooting and I tried to call the Honeywell tech support, which was frustrating. The support is outsourced and they kept telling me there should be AA batteries but this T-Stat uses only a button battery. The touch screen is easy to use. I purchased the Samsung SmartThings Hub and downloaded the app to remotely access the thermostat and apply automation. So far I love the ability.

Six months after purchase this thermostat quit a-wave communication with my home hub. Followed directions to reconnect but nothing worked. I phoned Honeywell customer support who offered none. They stated I was required to call a local Honeywell servicing HVAC contractor to service the unit at my cost. Other programmable features work well but that is not why I purchased this thermostat.

Rated 5 out of 5 by from A rock-solid programmable Z-wave! I wanted to upgrade our thermostat after installing a Z-wave home automation network, but didn't want to have to hassle with wi-fi, network security, & multiple control apps. Since our last thermostat was also a Honeywell programmable, this model seemed like the best solution. Installation was a 'no-brainer' (<15 mins) thanks to the included 'add-a-wire' device (a 'common' wire is required). Adding into our Z-wave network was also a snap and I LOVE the ability to remotely monitor or set the temperature while we are away from home (or even just upstairs). Have been running for 2+ months and this unit has performed flawlessly- I would not hesitate to recommend this unit.

Rated 5 out of 5 by from Excellent and Easy I purchased this to connect to my Honeywell Smart Home Security system and it rocks. I have a 4 wire bus from my air handler to my thermostat location and it worked great and was easy to install with the wire saver module provided. I have linked it with the zwave technology to my Honeywell Tuxedo Home Controller and now my thermostat knows what to do when I arrive home or leave. I would recommend this to any and all. Excellent product, Excellent functionality, and Easy to install.

Rated 5 out of 5 by from Awesome Z-Wave Thermostat I purchased two of these and have them tied to my security system. I can control them both from my phone, the alarm panel, the web and the actual thermostats themselves. If you aren't familiar with Z-Wave recognize that you do need to have additional controllers if you want to fully utilize all the features available. Even as a stand alone thermostat this thing is amazing. I love Honeywell thermostats!

Rated 2 out of 5 by from Great T-Stat, Horrible customer service and Z-wave functions I bought this as a replacement for my 14 year old 9000 series Honey stat that I have loved and worked flawlessly over the years. I purchased this specifically for the z-wave radio, to integrate into my home automation system, SmartThings. The thermostat itself is very simple to operate and while you do need the manual to setup the advanced features under the initial programming (all of the features are simply numbers, so you need to use the manual to identify the settings options), it works as expected and very similar to my previous 9000 stat. It does not have the option to add an outdoor temperature sensor as previous versions of the 9000 had, bummer. The stat has many options to allow for just about any kind of setup or model furnace/AC you can imagine. The display can be set to be always illuminated and gets brighter when you touch it- a nice feature to at-a-glance check settings and temp. The bad news.. the Z-wave radio is notorious for having stack communication issues. The unit links to the hub easily, but within a short time (in my case sometimes less than an hour), the message "communication lost" appears on the screen. I wish I had done more research on this model before I purchased it, because googling "Honeywell communication lost" brings up page after page of forums from a multitude of hub vendors about this very issue. I tried three different units (returning each one claiming a defect) and each and every one caused the exact same problem on not only Smart Things, but MiCasaVerde and also Wink (I have been experimenting with home automation so I have several different systems to play with). I did notice that the stat seems to work better in a zwave environment with very few devices. I believe the problem is with the stats ability to receive and pass zwave commands properly, and when it gets confused, it simply drops off the zwave grid. In order to reset the stat, you must physically remove it from the wall and then wait a few minutes and attach it again. Don't bother though, because you will only get the same problem to occur at some point very soon in the future. Obviously, this is a major deal breaker for this product, or why else would you even bother to purchase a Z-Wave enabled stat? Contacting Honeywell, that is an even bigger communication problem, as they couldn't care less about you unless you are a professional contractor. Fine, my neighbor (who also helped me install the stat) IS a licensed, professional HVAC contractor, and they gave him just as much of a run around as I did- reluctantly suggesting that it might not be compatible with z-wave systems unless they were Honeywell... so there you have it folks. Steer clear, your mileage may vary, but do yourself a favor and research this before going through the hassles of installing and wasting time trying to get this to work.

I purchased this thermostat for the Z-Wave technology and have it synced with Front Point, my Home Monitoring Company. I confirmed with Front Point before purchasing that this was in fact compatible. Unfortunately after paying an electrician several hundred dollars to install 2 thermostats, I now find out from Front Point that this Honeywell product is NOT compatible with their control unit. So I call Honeywell directly to find out my options. After 55 minutes on the phone with multiple customer service reps, they tell me they don't know who is compatible and recommend I call a few security companies in my area to find out. I should have just kept the original two in place which didn't have z-wave but worked perfectly fine as a thermostat and saved $800 in equipment and electrician costs.

Rated 4 out of 5 by from Good product but not what I thought The unit itself is fine - programming is relatively easy to follow. Only problem is that (and this is my fault) I thought that I would be able to program it remotely, rather than punching it out on the screen, but it seems that I need to have other Z-wave hardware/software that I don't have in order to do that.
