Essential Info

Want to control your home's thermostat from another room? How about being able to cool (or heat) the house while you're at work, or check the temperature when you're on the road? With the INSTEON Thermostat, you can control your home's temperature whether you're at home or miles away, saving energy (and money) and maximizing comfort.

Simply replace your existing thermostat* and link it to any INSTEON controller such as a Mini Remote, KeypadLinc** or your smartphone using the INSTEON Hub.**

*Replaces most standard wired in-wall thermostats. Not compatible with heat pumps or millivolt systems. Not sure if it will work for you? Call us! 800-762-7845
**Requires at least one INSTEON dual-band device (sold separately)

The INSTEON Thermostat also works like a standard thermostat with local control, four automatic modes and 7-day programmable settings--allowing independent settings for individual days, weekdays, weekends and every day--so there's no hassles with training your family on how to use it.

In addition to remote control, program the thermostat as an INSTEON controller to activate other appliances in your home based on temperature, humidity or mode changes. Here are just a few of the limitless scenarios:
  • When the A/C kicks in, turn on your ceiling fans to help cool down your home faster and more efficiently
  • Add INSTEON-compatible software such as HouseLinc and receive text messages if the temperature or humidity drops above or below your defined safe levels
  • If the humidity level climbs too high, turn on a dehumidifier with an ApplianceLinc.
  • Program a daily "Return" mode that turns on your A/C and switches on your outside lights so you come home to a relaxing, welcoming house

  • Add a Wireless Thermostat
    Did you ever wish that you could keep the temperature exactly right in a specific area of your home? Now you can by adding an INSTEON Wireless Thermostat to your INSTEON Thermostat. Put it in the master bedroom, in the basement, in the guest room--anywhere you want room-specific, customized temperature control. Up to two INSTEON Wireless Thermostats can be added.

    Room-Specific Climate Zones

    Much of the heating or cooling energy in a forced air system is wasted on rooms that are unused. Installing duct dampers can help to direct air conditioning to only the rooms that are actually needed. Dampers work by blocking the flow of air in the ductwork and can be installed to close off sections of a house or individual rooms, depending on the level of control desired. When wired to an INSTEON I/O Linc, a damper becomes a device on your INSTEON network that can be addressed directly by INSTEON devices and managed by an INSTEON central controller.

    Without a central controller, an INSTEON Motion Sensor can be added to rooms with dampers and linked to the I/O Linc. When motion is detected, the duct damper will open, providing heating or cooling to the room and when the room becomes unoccupied, the damper will close.

    Using a central controller like HouseLinc or Perceptive Automation's Indigo, the exact temperature in each room can be monitored and controlled. Adding an INSTEON Wireless Thermostat in each room that is configured with a duct damper can provide amazingly accurate and granular temperature control on a room-specific level. If the temperature in the master bedroom falls at night, the Wireless Thermostat will report back to the INSTEON Thermostat controlling your heating and cooling system, heating just the bedroom while keeping all of the other dampers closed to minimize the energy used. The same system can keep a living room walled with windows cool in the summer.

    Sensory Input

    Available for installation on every INSTEON Wireless Thermostat, a Waterproof Temperature Sensor can be added to provide monitoring of environments that are less than ideal for the thermostat itself. The small sensor bulb can be installed in hard-to-reach areas that are still critical to monitor.

    The temperature in a home's attic can greatly influence the temperature of the entire home. Using a Wireless Thermostat with the Waterproof Temperature Sensor mounting in the attic space, your home can monitor this often-ignored area and trigger heating and cooling events based on the attic temperature. Installing an attic-mounted circulation fan and On/Off Micro Module, your thermostat can exhaust hot air building up in the attic before your air condition system needs to work overtime to displace the heat.

    Just as much as the attic influences cooling costs, a frigid basement in winter means longer heater runs and the potential for disastrous water damage if temperatures approach freezing. Installing a Wireless Temperature Sensor with Waterproof Temperature Sensor in a basement can help keep the rest of your home warm in the winter by maintaining a minimum heat temperature and monitoring for freeze conditions that might cause poorly insulated water pipes to burst.

    Placing the temperature bulb in a pool or spa lets your home monitor areas not traditionally controlled by a thermostat. Configure an INSTEON Keypad button to turn on your spa pump and heater with an INSTEON 220V Load Controller and maintain the perfect temperature. The Wireless Thermostat will regulate the spa heater, turning it on to heat the water and turning it off when it reaches the desired temperature.

    System Interaction
    By far the most powerful aspect of the INSTEON Thermostat is the fact that it is a single component of an entire home control and automation system. Homeowners who have invested in an INSTEON system will likely find the nearly limitless options for expansion the biggest boon. INSTEON has always been a system that has only been limited by the imagination of the installer; a do-it-yourselfer's dream, INSTEON can be modified to work into any home and any set of conditions. There may be more legwork involved and the more you know about your home, the more you can achieve, but for those with the will, a multi-zoned, individually controlled, attic and basement monitoring HVAC system is an achievable reality.

    This thermostat requires power from the furnace or A/C unit to function. If you do not have a "common" wire running between your thermostat and heating/cooling equipment, you may need either to run a new wire or to install an Add-A-Wire kit.

    Because the INSTEON thermostat is an RF-only INSTEON product, at least one dual-band INSTEON device is required for it to communicate with your other INSTEON devices.

    Works as promised, but I wish I had checked the dimensions. Our house has standard sized outlet boxes for the thermostats wiring like a light switch would be held in, this unit does not fit and we now have a ugly gap and will need to put mounts in the walls to hold it. Now looking for a back cover to go behind to hide the gap.

    4 degrees low on ambient temp
    Nathan -- Arizona   5/26/2014
    Lack of heatpump support is entirely unacceptable. What competent engineer would design a product that won't work for nearly the entire southern half of the country?! Even the most basic cheapo thermostats from any hardware store can manage to run a heat pump, which is no more difficult to program or build an extra relay for. Until that missing feature is addressed, and factoring in all of the other reliability issues this model has, it is a waste of time and money to even consider this model. Get the venstar unit with the insteon add on if you want remote control. It is built as a good thermostat to begin with, with added insteon as an option. This one seems like an insteon device with some junk thermostat features piled on top. It was not designed as a proper thermostat from the beginning.
    Smarthome response: We hear you, Nathan. Thanks for your feedback. We will pass this on to the INSTEON team. As you mentioned the Venstar with INSTEON adapter is a great solution for those with heatpump systems (#2441V).
    Josh -- ca, CA   5/3/2014
    I love this system. It's easily the most cost effective and flexible system on the market. Combined with indigo or home seer it can't be matched. However, there is no programmatic way to set or query whether the unit is set to be the master controller. A huge omission as it limits flexible programming. Hopefully it will be fixed in an updated unit soon!
    Chris -- Minnesota   4/18/2014
    Installation of thermostat is easy, but getting it to connect to the hub is now at 3 hours and still not working. Set up for remote monitoring requires an IT degree - very difficult. No where does it say you need a computer to set stuff up. Everything should be able to be done with the app.

    The product itself works great and is no doubt a quality thermostat. Their customer service people are friendly and helpful however their return system is very slow.
    Dekalbbear -- dekalb, IL   2/25/2014
    Love the thermostat, but hate that to turn on the backlight it also changes the setpoint! BUG ALERT! Now way to program the backlight on/off in the ISY. FAIL!!!
    BRANDON -- madison, WI   2/24/2014
    I tried two of these units. Both had the same problem. The units would randomly "reboot" themselves. The screen would go completely dark (not talking about the backlight - but the entire LCD) then a few seconds later they resumed operation as if they had been rebooted. Too bad, love the concept, just no reliable
    ALEXANDER -- allen, TX   2/19/2014
    Much more robust product over the Venstar thermostats. Keeps accurate temperature
    STEVEN -- rochester, MI   2/13/2014
    Works great so far. Have it as a stand alone thermostat so far since I haven't set up an Insteon network yet.
    diesel94 -- rockford, IL   2/1/2014
    I purchased a 2441TH on Ebay as a NIB item and installed it in my new Insteon home setup. I'm converting from the no longer supported X10 system. The unit worked well at first, but after I added some additional switch to the system, the thermostat stopped responding to the network still functioned as a stand-alone thermostat. I looked on-line for an answer and saw complaints of short lives for these units. Thinking I'd purchased a lemon, I wrote a negative review. Afterwards, I purchased a plug-in dual band repeater and placed it near the thermostat. This cured the problem and the unit has functioned perfectly since. The real surprise was I received an email from Smarthome offering to exchange my thought to be defective unit, even though I bought it on Ebay from a private seller. Now that's service! It also demonstrated to me the willingness of Smarthome to stand behind their products. The thermostat continues to work flawlessly and with the support shown by Smarthome, I've got to give this product 5 stars.
    JASON -- chula vista, CA   1/15/2014
    Works as advertised. The only slight annoyance is the temperature displayed in the insteon hub app doesn't always auto update every time I open the app. Sometimes it shows an old reading from a few hours ago and won't update until I open the interface to control the thermostat. Would be nice if the app synched with the thermostat every 15 minutes or so to stay updated. Otherwise there is no reason to have the temperature displayed at the bottom of the app if it isn't accurate.
    Brad Bauman -- United States   1/14/2014
    You better be an engineering if you hope to get this device to work...wait, I am an engineer. If you just want a thermostat, this works. If you want it to control anything or send alerts using HouseLinc, forget it. I wasted hours of my life, no days, trying to get this to send me a message if my house went cold. Tech support, when you can get them, suggests a few things and then says, it should work. I tried two different thermostats and got the same results; they cannot send messages based on any logic. They do send messages but you can't control when and if they will be sent. My situation has been elevated to an issue but who knows when and if they will ever contact me. A modest competitor could eat these guys' lunch; they have the worst, and I mean the worst, tech support system I have ever come across. The techs are trying but the whole system is terrible.
    JOSEPH -- palatine, IL   1/13/2014
    Did not work with my furnace.
    DAVID -- austin, TX   1/12/2014
    They really need to put in bold letters on the description that it DOESN'T WORK WITH HEAT PUMPS. I know there is a tiny mention of that right in the middle of that wall of text, but they need to make it way more obvious in bold letters so everyone knows that before they order.
    rga48 -- jupiter, FL   1/6/2014
    This product does not work with resistive heating elements in AC Systems. This fact is NOT clearly stated in the on-line advertisement or in the installation instructions provided with the thermostat. This information appears on page 11 of the instruction manual. I wasted hours finding this defect in design. When I called the help desk, the representative had no knowledge of this deficiency. This should be a simple design change to power on the fan G when power is on heat W terminal. The current design powers only W which powers the coils but not the fan G. I tried a jumper between W and G put that turns on the heater coils when the AC activates both the Y and the G terminals.
    JC3 -- clinton twp, MI   1/4/2014
    LCD is very poor, when I look at the screen it shows 168 degrees. Then I look straight on it shows the correct screen. Programming very difficult.
    LARS -- ithaca, NY   12/31/2013
    Has all the functionality of a regular 7 day programmable thermostat, but with the added functionality of being controllable from afar, together with lots of other devices. Note: not all of the on-device functionality is available through remote devices.
