    Works well; but try to use it with the newer 6v power supply Review by Luke
    Works well; but try to use it with the newer 6v power supply
    Rating

    I'm using this to control a HVAC duct booster fan in order to pump air to my finished attic. It works very well for me. It has been reliable though it has failed to turn off the booster fan a couple of times (rare though). The device is far away from the relay (2 floors away) so I suspect this would work better if closer or if I had more devices.

    Pros:
    - Looks nice
    - Temperature and humidity readings are accurate (I cross-checked it with some other sensors)

    Cons:
    - 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.

    Other thoughts:
    - I am using this with the 6v power supply so that I can query the temperature remotely. The device seemed to intermittently respond. However, Insteon sent me an newly designed power supply (without my asking) and the device works more reliably now.

    Works perfect Review by GeorgeG

    Rating

    I use this as a wireless controller for 2 space heaters which are plugged into 2 Insteon outlet modules. Works perfect and is like having central heat with very precise control. If you want this to control your central HVAC system you need to start with the wired controller and use this as a remote sensor/controller.

    Not Good for Standalone Use Review by Heavy Insteon User
    Not Good for Standalone Use
    Rating

    This thermostat does not work as described as a stand-alone thermostat/temp sensor device controller. I purchased 3 with very high hopes -- none worked and with many tests were conducted. I've got a couple hundred Insteon devices in normal scenes and/or controlled by ISY so I'm not a novice.

    It may work fantastic when linked to the wired version but is worthless stand-alone.

    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.
