  • What's Included
  • Place a thermostat anywhere you want with the INSTEON Wireless Thermostat linked 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. You can add up to two INSTEON Wireless Thermostats to your INSTEON Thermostat.

    Additionally, you can use INSTEON Wireless Thermostat as a standalone controller, activating scenes to turn on heaters and fans based on the room's temperature and/or humidity status.

    The INSTEON Wireless Thermostat also works like a standard thermostat with local control, four automatic modes and 1-day programmable settings, 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


    • *You must have an INSTEON dual-band device or Access Point installed for INSTEON Wireless Thermostat to communicate with single-band INSTEON devices.

      Increase INSTEON Wireless Thermostat's utility by attaching a Waterproof Temperature Sensor. This weather-resistant external sensor wires into INSTEON Wireless Thermostat and allows you to monitor the temperature of environments such as pools, spas, aquariums and ponds.

    You can link up to two INSTEON Wireless Thermostats to INSTEON Thermostat, allowing you to control the HVAC system from anywhere in the house. When linked to an INSTEON Thermostat, INSTEON Wireless Thermostat can serve as the master thermostat over the HVAC system; just press and hold the Master button, wait for the beep and release. When "Master" appears below the large temperature display, Wireless Thermostat is now the primary thermostat.

    Temperatures from the linked INSTEON Thermostat, Wireless Thermostat and/or Waterproof Temperature Sensor are displayed in smaller digits centered above the main temperature display in positions 2 and 3, with the master thermostat featuring "Master" below its temperature reading. The display information updates every time the temperature sensed changes by 2&deg.

    INSTEON Wireless Thermostat features a bright blue LED backlight for easy programming. By default, the backlight turns on when a button is pressed and turns off 10 seconds after button is released-this helps to conserve Wireless Thermostat's battery life. You can change this setting with the Program button to 60 seconds, always on or always off.

    If the INSTEON device you intend to control from the INSTEON Wireless Thermostat does not receive RF signals (i.e., it's powerline only), you will need at least one dual-band INSTEON device to convert the RF signals to powerline signals.

    Received mine this week. I want it to communicate with home control software so I need to go the external power route as on batteries it goes to sleep and won't take external commands.

    Similar to what Smarthome sells, I tried a 6VDC/800mA but the humidity was jumping all over the place. This has been documented in other online forums. I tried several more adapters rated as 5V. If they produce less than 5.09V then the external sensor doesn't appear to work correctly.

    The solution that finally worked for me was the genuine Apple iphone square wall plug rated 5VDC/1A and a usb cable stripped at one end for +/- power. That produced 5.19V and now the humidity is stable and the external sensor is also stable. Hopefully this can help others facing this same problem.

    Very nice unit. I'm using it as a remote sensor for the 2441TH unit. Not only does it function as a remote sensor - but the unit is totally in synch with the main unit. I can program from either one and the other one gets the update immediately! Nice!!!

    Fantastic product. I have it controlling heat and humidity to our nursery room with the use of plug in on/off modules connected to independent devices.

    This is an update to my previous review.

    Tried to have my thermostats, wireless and wired to the factory reset state, then connected them to each other.

    Since the wired thermostat has default pre-programmed modes for wake, leave, return and sleep, which cannot be disabled, I used to set the wireless thermostat as MASTER and confirmed that HOLD was set ON.

    Since then, both wired and wireless thermostat are stable, and do not change their current mode as they used to do.

    I believe preprogramming should have an ON/OFF toggle for people who do not run on a schedule, and the default must be OFF. In addition, once a wireless thermostat is connected and set as MASTER it should have the ability to access programming button.

    I highly recommend using this with the AC adapter. Understandably due to power consumption concerns when operating on battery, when it goes to sleep I could not seem to figure out how to make changes remotely.
    I'll be honest I still have not figured out how to use this as a simeultaneous secondary thermostat.
    Here is an example: If it gets to cold where this thermostat is located, turn on the heat, OR if it gets to cold where the primary is located turn on the heat. I can only seem to figure out how to have one or the other act as the "active" thermostat, if you will.
