    Excellent unit Review by Health Highway
    Excellent unit

    I installed this unit a year ago. This needs a common wire and fortunately I used a spare wire coming to thermostst and connected to common on the furnace. It has been working great bi an access and control temp from my iPhone from anywhere.

    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.
