    Z-Wave Compatibility
    Z-Wave can help you economize your energy usage by controlling this thermostat, as well as many other devices throughout your home. You could create automated heating or cooling routines based on occupancy or other conditions. For example, when noon sunlight warms up your home, Z-Wave can automatically lower your motorized window shades, which in turn will tell the thermostat to adjust itself to a correspondingly economical setting. Z-Wave can monitor your entire home's energy usage in just this way, 24/7, which provides you with maximum savings and makes your home greener.

    Convenient and Efficient for At-Home Comfort
    You know that turning down your heat at night saves you money, but you hate waking up and making breakfast in a freezing cold kitchen. You also don't want to run your AC all day while you're at work, but you want your home to be cool and comfortable when you get home. These issues, and more, are solved with a programmable thermostat; simply set schedules for when the thermostat should operate that are convenient to your schedule. The customized settings add luxury to your home while affording you valuable savings on your energy bill.

    An Easy Way to Save Energy and Money
    If programmed as directed, this thermostat offers you the ability to save up to 33% on annual heating and cooling costs (savings may depend on the geographic region you live in and your energy usage).

    Convenient, Intelligent Features and Broad Compatibility
    This thermostat delivers permanent day and time settings that are even maintained during power outages, and it offers the option of automatically adjusting for Daylight Savings Time, as well as a filter change reminder function that can help you keep your heating/cooling system operating at optimum efficiency.

    This thermostat is compatible with a broad range of 24-volt heating and air conditioning systems, including both single-stage and multi-stage heating and cooling systems, heat pumps with and without auxiliary (back-up) heat, gas fireplaces, steam or gravity, hot water, and heating only or cooling only systems. It is not compatible with electric baseboard heat (120-240 Volts) or 750 millivolt systems.

    Some homes, perhaps yours among them, have the existing thermostat wired with 4-conductor cable. This intelligent thermostat is capable of sending separate commands to the AC compressor and to the circulating fan, but this requires a "common" wire. In case your existing installation does not have a common, use the included Wiresaver module to install this thermostat. The Wiresaver acts as a splitter and carries both compressor and fan commands over one of your existing conductors. It's simple to install and is mounted next to your HVAC system.

    There is some type of Z-Wave Firmware bug that does not allow this thermostat to work on a 2GIG Go!Control panel. Tried multiple version of software of the 2GIG panel and it will learn into the network, but does not allow the thermostat to function properly. In talking to 2GIG and Sigma Designs (the Z-Wave folks) I found out that HW used a different version of the Thermostat command class, making it incompatible with 2GIG panels and as Sigma said probably most other Z-Wave controllers.

    Received my Honeywell thermostat very fast from Smarthome, packed well and undamaged. I already owned the equivalent style unit (Vision Pro TH8000) that I had installed several years ago with my A/C-heat pump. I was used to the layout and touch screen UI and found it comfortably familiar in operation to the old Honeywell model. The new unit used the identical wire connections, so that part of the install went quicker than the original very involved learning curve. The myriad of option choices in the complex setup is paid back however by allowing for a wide range of HVAC configurations. Very comprehensive. The Zwave model, though very similar in appearance is larger in every dimension. Make sure there is enough room between trim moldings for this larger "wall print." One other note: On the old tstat I had the optional external temperature probe and there is no provision for that option in the ZWave model. Initially I chose to not use the thermostat's programmable schedule as I was anxious to get the new unit into my Zwave network and check it out. The inclusion went flawlessly and my Vera saw it immediately and the response is near-immediate on temp or mode changes. I've since decided to use the Vera controller exclusively to operate the scheduling, I also have a mini-split that is controlled with the Remotec Zwave IR controller and several fans that I don't wish to be running during the day when we are away and the A/C is essentially off. Such unnecessary air movement tends to warm the house by convecting currents around less energy efficient windows. The Vera scene allows those ancillary devices to be turned on and the evening temp set all from the same scene programming. That schedule is easily disabled (or modified) when we will be late or away for a few days. The temp can be adjusted and monitored remotely by smart phone for a return to a comfy home. All and all this has been an excellent addition to my home automation project/hobby.

    Fantastic Product, easy to install, and the Z-Wave was easy setup
    JAMES -- brookline, NH   1/27/2014
    Installation was a snap, even the holes on the new backing plate of the thermostat lined up with the old screw holes in the wall. Now for setup. There were two manuals with the thermostat (installation guide and operating manual). Use the **Installation Guide**. Page 6 in the installation guide shows you how to get into the installer setup which allows you to configure everything. The operating manual on page 12 shows you how to get into advanced functions which contain some of the installer functions but not all. Just use the installation guide and follow directions and it works great. Added the Thermostat to my ZWave network first try and now have remote control from my phone. This Thermostat is compatible with 2-transformer systems (separate Heat Rh and cooling Rc) leads. Just remove the jumper wire connected between Rc & Rh. It's been up and running for over a month with no issues. Great product.
    CHRIS -- annapolis, MD   1/23/2014
    Very happy with this product (I purchased 2) & SmartHomes service. The only thing that would make it perfect is some help understanding how many stages of heat or cool my system is. While this isn't necessarily Smart Home's responsibility, the nature of all these products is DIY & you need to know this about your HVAC system to properly set up your Tstats.
    GEORGE -- schertz, TX   11/10/2013
    Follow the instructions and it will work great. Its nice to control the cooling from your bet.
    Barry -- fort worth, Texas   8/17/2013
    Works great. For those of you interested in integrating in with ADT Pulse system, it works great with the system
    JAMES -- mesa, AZ   7/28/2013
    Thermotstat works well, Z-Wave integration with my Vera 3 works perfectly. I first tried using the Wiresaver module, which I could not get to work properly. It was easier to just run a new control wire with the proper connections.
    JUSTIN -- edgewater, FL   7/20/2013
    Worked great with my z wave integrated lynx 5100. Directions for application with this system could have been better but after figuring out how it worked together my thermostat and security system are working in harmony. Great price from Smarthome.
    MARK -- frankfort, KY   4/14/2013
    The thermostat works great with my Homeseer system. It was easy to install. My old thermostat only used 4 of the needed 5 wires but the wire had all 5 conductors so it was a minor change. The wire color codes on the furnace are standardized and the letters matched up with no problem on the thermostat. The touch screen is fairly intuitive to setup and to use. The only problem was a lack of documentation on Homeseer. For those who want to use it with Homeseer you need this type of call: Temp = hs.Plugin("ZWave Thermostats").GetHeatSet(1) There are a variety of functions like GetHeatSet to read the heat setting, functions to set a new setting, switch from heat to cool, etc. Homeseer will work with multiple thermostats on the same system (different zones). Highly recommended.
    DAVID -- sterling heights, MI   4/6/2013
    Excellent value, very nice thermostat, was delivered promptly and in safe packaging. The thermostat was easy to install, remove the old one, match the wires and then attach to the wall.
    JANICE -- cape coral, FL   2/23/2013
    Does exactly what we wanted it to do. Easy to install and program. A keeper.
    DAN -- oakville, ON   1/7/2013
    This product shipped on time and worked as advertised. Very happy with the service.
    Brian J -- minneapolis, MN   1/3/2013
    Works great on z-wave for our rental cottage. I can adjust fan, temp, heat, cool, etc. Not many control the fan, and thats nice to have. Easy set up to Z-wave too.
    bill m -- vancouver canada   12/3/2012
    fantastic easy set up and works great.
    SOLOMON -- hartsville, SC   10/9/2012
    Works great! I had 4 units professionally installed. I linked them to my network witout any difficulties.
    Mike -- boston, MA   6/25/2012
    Very easy to install; only took a few minutes. The setup was easy as well with a simple wizard to get going. Controls are also intuitive. I ended up not needing the wire saver as I found the wires were there, just cut so was able to strip and wire at the HVAC panel and at the tstat. Adding to Zwave network was also very easy with only a couple easy steps. Seems to be communicating fine with my Homeseer box. Just purchased another one for the other zone in the house.
    Brad -- phenix city, Alabama   6/14/2012
    Had an electrician hook it up to a heat pump. This thermo has worked great. Have it set for temperature changes in the evening and the morning, works like a charm. Love how it works with z-wave and the app for android.
    Happy Customer -- Oklahoma   6/4/2012
    This thermostat works well. Setup is somewhat involved for multistage heat pumps but the instructions are easy to follow. Z-wave was easy to setup and works well with a Micasa Verde.
    B Smith -- frankfort, Ky.   4/26/2012
    I would never buy another one of these I set temperature and the house will get hot so I check the termostat and it is on 84 would never recommend one of these wish I had my old cheap thermostat back.
