  • What's Included
  • 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 for me Review by Timmcd1
    Works for me

    I've had this thermostat installed for well over a year now, with no real problems. It's been under ISY control the last six months. My only complaint is that in order to get the display backlight to turn on,one must press a button, changing a setting. The firmware should be updated so that the first button press only turns on the backlight.

    Energy mode issue not resolved Review by Perry
    Energy mode issue not resolved

    This is a great thermostat, except for one bug that Smarthome refuses to acknowledge. The unit goes in and out of "energy mode" on its own when called to heat the furnace. From reading the comments here and other places, I believe the problem comes from signal interference generated by furnace igniter and conducted to thermostat. It is odd that thermostat can behave the way it does without a formal command to put energy mode on or off. But the problem has gone on for 2 years and Smarthome does not acknowledge. I have now read 12 or more different people's account of same issue.

    Disappointed Review by Frank

    This device stopped work after 3 days. During the 3 days it kept rebooting and displaying a two digit number and beep into the morning. Very disappointed in this product.

    only works with some wiring Review by cstork
    only works with some wiring

    You need to have 5 live wires for this thermostat to work. Doesn't work with older furnaces. Check your thermostat before buying.

    Works GREAT Review by Sully
    Works GREAT

    Thermostat itself, great, 5 star. Integration with Hub, eh, seems to only change temp and let you connect to scenes. All other settings only accessible on the stat itself, -1 star.

    My install, terrible. 40 year old HVAC system, no Common wire. Fortunately, the existing thermostat wiring had a spare wire in it. Had to tear into Air Handler to find the Transformer and connect the spare wire to it's Common. Installing on my ancient system was a pain, but now its working, it rocks, and already using it to adjust temps when away.

    Review of 2441TH

    This thermostat is easy to install and it works great with the ISY994i. I have two, one is direct wired to my furnace and A/C and the other is programmed through the ISY to control the temp in my master bedroom. Both work have worked great without any problems. I just wish Smarthome would develop one has a basic one day program and is cheaper. All program can and is done through the ISY so why pay for a seven day thermostat.

    Review of 2441TH Review by ar26pt2
    Review of 2441TH

    This unit is in my house working well for over a year now. It was very finicky at first. I use Indigo to control it, and with some scripting I got it working well. The problem is that There are five modes that can be selected from the unit: OFF-AUTO-AUTO*-HEAT-COOL. The first AUTO mode is the one that allows control thru insteon, the rest are for local device only and do not accept insteon. AUTO* is only distinguishable by the panel displaying a daypart on the right like sleep, wake, whatever and it the panel's own internal program. The problem is that many times the panel will revert back to this AUTO* mode, I think as a result of adjusting the temp up or down on the panel so local adjustments tend to abort the insteon conrol. Furthermore there was a problem with the thermostat not actually changing temp settings despite the insteon feedback saying it did, resulting in no actual change in settings. Anyway, I wrote a script that first resets the mode on the thermostat to the first AUTO mode indigo.thermostat.setHvacMode'devicename', value=indigo.kHvacMode.HeatCool then wait a couple secs then send the temp adjustments. THEN I have the script repeat itself in about 10 seconds just incase it didnt correctly actuate the first signal. It has basically been working without issue since then. Maybe the newer ones have updated firmware that fixes these issues- I dont know. The humidity was about 15% off but seems to trend correctly. The temp was about 2-deg off but I was able to recalibrate.

    Review of 2441TH

    Excellent Thermostat. I have it linked with the Insteon Hub.
    Just one suggestion: We use Centigrades in Canada where settings of half degree are common within other programmable thermostats.
    It would be great to the half degree setting available in future software updates for the 2441TH

    Review of 2441TH

    This was an easy install and programming. I have been using it about two months and it works well from my windows phone while traveling. It did need calibrating when it arrived. Very easy to do.

    Review of 2441TH

    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.
