Essential Info

Control the temperature from anywhere in the house! This Venstar Thermostat allows you to recall stored set point/mode settings from any INSTEON-compatible controller. Faster than grabbing a blanket, you can use your coffee table RemoteLinc to recall "comfort mode," bringing the room to the perfect temperature. When turning off your lights for the night from your bedside KeypadLinc, you can also save some energy and money by recalling "energy-savings mode," which minimizes the activity of your HVAC system while you're sleeping. Because you can program any button on an INSTEON controller to any temperature and mode on the thermostat, the possibilities are endless.

This product contains the Venstar T1800 thermostat along with an embedded INSTEON Thermostat Adapter; this thermostat requires power to function. If you do not have a "common" wire running to your thermostat from your heating/cooling equipment, you may need either to run a new wire or to install a thermostat Add-A-Wire kit.

Set up different heating/cooling programs to best fit your schedule. A program can be set up for each day of the week, so you can completely customize your climate control, even if it varies from one day to the next. If your daily schedule tends to stay the same, simply the programming process with the
1-day programmable version.

Note: Because the thermostat is an RF-only INSTEON product, at least one dual-band INSTEON device is required to communicate with your other INSTEON devices. This thermostat is not compatible with Venstar accessories that connect via the jack (located at the bottom of the unit).

    Smarthome is always on time and as advertised
    JAMES -- pittsburgh, PA   12/16/2012
    While I have had issues this this thermostat, Smarthome and Ventstar have continually resolved the issues. I'm very happy with the service that Smarthome has provided and will continue to patronize them in the future.

    I purchased 2 of these thermostats, as part of a whole home automation project. Unfortunately, once a read the manual, I discovered that they are not remotely programmable. That is, I expected to be able to program all my temperatures and 7-day scheduling via the Houselinc software - or at least some other means. However, from what I read, it appears that you can only manually change the temperatures, one increment at a time. I saw no means of programming the devices remotely. For that, you still have to be at the devise, pressing buttons in confusing and complicated patterns, like a teenager playing World of Warcraft. The thermostat is, otherwise, a very clean and nice looking device. Obviously, I would just like to see Insteon make it more user-friendly - fully remote programmable.
    Chad E -- atlanta, GA   10/30/2012
    After installing this thermostat I thought it worked great. Then I started noticing wide swings in the room temperature. I placed a traditional thermometer beside the thermostat and noticed the thermostat is often off by 1-2 degrees. In the summer, this means the house would get very warm before the air conditioner came on. In the winter, it gets very cold before the heater turns on. I calibrated the thermostat, but still have the problem. Sometimes the temperature is displayed correctly, but often times it is 1-2 degrees off. The wide swings in room temperature may cause me to find a different thermostat. I've never had this problem before.

    Was difficult to get working with ISY99i out of the box as the instuctions that came with it are poor and the online ones aren't much better. Once it was configured it only worked for about a week before it lost communications with the controller. Also, it would sometimes shutoff no power completely for seconds to hours at a time? Smarthome sent me a newer version after repeated attemps to getting working properly. The new one no longer shuts off but it still doesn't function properly!

    Worked for a short period, now it doesn't only a month or two later. Very disappointing when u consider the work to get it running.
    Michael -- blue springs, MO   4/18/2012
    Bought two of these and got them wired in fairly quickly. They are really easy to setup and so far work great! Insteon is sweet!
    ERIC VAN -- oregon, WI   3/14/2012
    Worked well for the first week, then the Insteon functionality stopped working altogether (would not communicate with Houselinc and the set button no longer functioned). Tried resetting to factory defaults but no success.
    MATT G -- carthage, IL   3/11/2012
    I only wish the integrated INSTEON was available the FIRST time I bought one of these. Nice!
    CHRISTOPHER -- poughkeepsie, NY   2/29/2012
    INSTEON integration and usage is not well documented.
    WENDY -- modesto, CA   1/25/2012
    Great to have in the house since I can now use my iPhone to adjust the room temperature of turn of the AC when I forget (often from the road using 3G and the ISY99i). Only issue is that the iPhone app always shows the humidity reading which is a false number since I don't have the humidity module. There is no way to turn this off so I have just adjusted to live with this fact :-(
    DAVE -- bloomington, IL   1/22/2012
    The new integrated Insteon interface combined with Mobilinc HD is a substantial improvement. Great for remote access and monitoring your HVAC system.
    Peter Von -- Freeport/ Bah   1/6/2012
    Of the six T1800 I had purchased in 2009 - 5 failed over a period of 18 months. First the displays where not lit anymore and shortly after they totally failed. Other then this they worked good with the remote. I did replace them with the less costly T1700 and had no failure within the last 18 month. However, Smarthome refused to replace the defective products on the base I had reordered the model T1700 !!!
    ssiemer -- scotts valley, CA   1/5/2012
    Very nice unit. Works flawlessly with my ISY99i. Be warned that this device does not support microvolt appliances! You have to get a seperate power supply and relay - kit is available through Smarthome. I like the extremely flexible time-zone programing.
    ARLEDGSC -- bay area, CA   12/31/2011
    Performs well in my ISY-99i controlled home system. The T18000 is an extremely versatile t'stat on its own without Insteon capability. Add the ability to monitor temperature and adjust via Insteon network is a real luxury that I would not like to give up. Had to pull new t'stat wire but knew that before I purchased. I would rate it 5+ stars if it had battery backup to keep the clock up-to-date and previous mode after a short term power outage.

    No battery backup in case of powerfailures.
