    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.

    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.
    JOHN -- littleton, CO   11/6/2011
    Easy to install and configure for Z Wave, easy to use graphics on the screen.
