    Control your thermostat from anywhere - in your home from an Insteon Keypad or on the road from your Smartphone with the Insteon Hub.

    System Support

    Our range of thermostat offerings ensures that even the most custom HVAC installation can be controlled.


    Insteon Thermostats fully integrate with your Insteon automation system. Automatically control duct dampers, ceiling fans and more.


    When one thermostat isn't enough, add Insteon Wireless Thermostats for additional temperature monitoring and throughout-the-home control.

    Smartphone Remote.

    Because carrying the thermostat around is just silly.

    When you install an Insteon Thermostat in your home and link it to the Insteon Hub, every smartphone and tablet you own becomes a remote control. It doesn't matter if you're hiding under the covers on a cold winter morning or running late out of the office on a sweltering summer evening, you can adjust the temperature from anywhere and ensure that your home is comfortable all the time.

    Winter Weather Watch

    Keep the blizzard outside and ensure your home is toasty warm by turning up the heat remotely.

    Summer Sun

    Cool down the house when you're on your way home on a blistering summer afternoon.

    Bon Voyage

    Turn off the AC even after you've left. Especially helpful for impromptu expeditions.

    Control on Apple Watch

    With the Insteon App on Apple Watch, you don't even need to reach for your iPhone to adjust the Thermostat. Change your Thermostat mode right on your wrist. (Disclaimer "Mode control only. Set point and fan currently unavailable from Apple Watch. Feature will be added in a future software update.”)

    Supported Systems

    A wide range of heating and cooling devices.

    Insteon Thermostat works with most heating and cooling systems found in homes and many businesses. With the exception of heat pumps and sophisticated triple-stage systems, your home's heating and cooling system is most likely compatible with Insteon Thermostat. In addition, Insteon Wireless Thermostat gives you control over line-voltage and millivolt heaters.

    Multi-zone ready.

    You don't need to have a mansion to benefit from a multi-zone thermostat system. With the Insteon Thermostat, you can connected up to two additional Insteon Wireless Thermostats for remote temperature monitoring in your home. Place one in the hottest room in the house and use it as a basis for cooling your home. Add one to your guest bedroom and let the in-laws have a say in household temperature. Or simply move the temperature sensing from a dark and deserted hallway to the center of your home.

    Venstar Adapter

    Extend the functionality of your existing thermostat.

    The Venstar Thermostat Adapter connects to the accessory port on the bottom of select Venstar and Totaline thermostats³. With the Vesntar Adapter installed, your Insteon home can read the temperature, change modes and adjust the heat and cool set points. And if you have a heat pump or advanced dual-fuel system, the Insteon Venstar Adapter inherits the capabilites of your thermostat, give you Insteon control over sophisticated HVAC systems.

    Convenient Review by jmight

    I found I was able to program these units to lock out the face buttons, basically removed the A/C vs Heat wars going on in the office. Great feature.

    Not all option available on app Review by Salar
    Not all option available on app

    Good piece of equipment but needs some improvements.
    - It's hard to read the LCD from angle compare to the old digital ones.
    - All options are not available in app and most of the settings need to be done on Thermostat - Like day Modes, Time and Day setting (Which is a default features in all WiFi thermostats)

    Beware This Thermostat In Some Situations Review by Kevin
    Beware This Thermostat In Some Situations

    This thermostat is apparently susceptible to voltage regulations issues, e.g., if the furnace control board provides more or less than the specified 24 volts AC, this unit will not work reliably. The unit completely froze (would not accept any button inputs, even factory reset) with the heat off and there was no way to turn on the heat without replacing the thermostat. it also has the screen go blank when the heat comes on, to return the display and the backlight a few minutes later. My original Honeywell programmable thermostats had no such issues.

    Works but not quite as resposive as I'd like. Review by XrXca
    Works but not quite as resposive as I'd like.

    When I installed it it kept losing power, turns out that was some bad solder connections on the furnace fan control board, after replacing that everything is working fine.
    It seems to have a wider range for cut in/out than the old one, so I see peaks and valleys on a temperature graph that weren't there before, although I do wonder if going back to Fahrenheit from Celsius would help a bit.
    I do have to say that the "Need 5 Wires" mantra is only applicable IF you are using both Heating and Cooling, with just one or the other (usually Heating) you can just drop the other connection from the equation, and four wires is all you need.
    And I'd second the complaint about needing to press a button to turn on the back light, and that changing the settings rather than ignoring the first button press.

    Mandatory accessory warning! Review by macsrwe
    Mandatory accessory warning!

    Before you buy this thermostat, check the wiring to your current thermostat. If it has four wires (most older homes do), you WILL need to add the Venstar Add-a-Wire unit to your order, or you will not be able to install it. Once you have all the needed equipment on hand, installation goes smoothly.

    Works well with Universal Devices ISY994 Review by John
    Works well with Universal Devices ISY994

    The information indicates this works with the Insteon Hub, but I use the Universal Devices ISy994. This thermostat is supported by ISY and works very well!

    Half the price of a Nest Review by serg
    Half the price of a Nest

    This might not have the bells and whistles that the Nest touts but for half the price I get to remotely control my thermostat. I've heard that most Nest users end up not liking Nest's inability to learn. I should clarify that while the Insteon thermostat is $149 (vs Nest at $249), you do need an Insteon hub ($39 at the time I write this). That's still less than the Nest AND I can add Insteon wall switches and outlets to remotely control other lights and appliances around the house.

    Wonderful device Review by George the architect
    Wonderful device

    I have installed these thermostats in two of my homes and I can monitor and adjust the temperature and monitor the humidity from my I phone anywhere in the world. If you gave a five wire system great. If not use the add a wire adapter to make a four wire system compatible. Also works great as a programmable thermostat for two day plus five day or seven day programmable options.

    Review 24441Th Review by Mark
    Review 24441Th

    Have installed a number of these units both using 5 wire and 4 wire (using add a wire) and all have worked as advertised. Some units need to be calibrated but most are very close. I use universal devices to control and really appreciate the humidity readout here in Michigan.

    Works well; but make sure you have 5+ wires to your thermostat Review by Luke
    Works well; but make sure you have 5+ wires to your thermostat

    - Looks nice
    - Temperature and humidity readings are accurate (I cross-checked it with some other sensors)
    - Clear labeling to make install easy

    - Requires 5 wires to your HVAC system (need to run new wire or get an adapter to make it work)
    - Doesn't have a good way to turn on the backlight. It comes on when you press a button on the thermostat (such as the temperature up button) but that means you have to increase the temperature to get the backlight on. I believe newer ones have fixed this by making the set button accessible without opening the cover.
