Essential Info

If you use a Venstar or Totaline programmable thermostat, you can monitor and control your home temperature via telephone using Venstar's ACC0433 Comfort Call Wireless Thermostat Telephone Controller. The included radio frequency (RF) receiver simply snaps into the RJ-11 port of the thermostat. The base unit connects to your phone line. When you call in from any remote phone or cell phone you will be prompted to enter a Security Access Code. Once confirmed, the base unit wirelessly sends and collects information to and from the thermostat. You can use touchtone buttons or voice commands to check the temperature or adjust the temperature settings. The controller accommodates up to four thermostats and additional RF receivers (SKU 30417) are available.

    CARL -- los altos, CA   2/10/2014
    I am using this in conjunction with the Venstar T1700 thermostat in a second home in a high elevation location. I it very useful to warm the home in advance of arrival as well as maintaining a minimum temperature so the pipes won't freeze. The manual is a bit cryptic and takes some interpreting. Plus the unit doesn't actually operate exactly as described in the manual. It took a bit of trail and error to figure out how it actually worked. However it does work and is a perfect solution for a location without any internet connection and only a phone land line.
    Bruce -- Ontario Canada   11/26/2013
    This simple device is amazing. We call the cottage and hear the inside temperature and then turn the furnace on. The cottage is warm when we walk in. It allows us to run the cottage just above freezing inside, with minimal propane used and still be warm when we arrive. We just turn down the temp as we walk out the door, till the next weekend.
    ALLEN -- cohoes, NY   11/1/2013
    The wireless controller we purchased along with the venstar T1700 thermostat to monitor another property would not pair, we quit after 2hours and sent it back. Customer service was great with the return.
    MICHAEL -- longview, TX   9/27/2012
    A snap to install and setup.
    LEO -- sacramento, CA   5/7/2012
    Easy to install.
    Johnny D -- collingwood, Ontario, Canada   3/31/2012

    SUSAN -- maple grove, MN   8/15/2011
    very easy to use
    JOE -- germantown, TN   7/16/2011
    The controller is easy to program and very easy to use. This product, along with the Thermostat is savings me about $200.00 per month. This is a wonderful conbination.

    G SCOTT -- toronto, ON   10/28/2010
    Works well. Don't have internet at the summer home so needed telephone based control. Voice menus are read very fast. Note that this will only allow you to have two "Settings", which you need to program at the site. You can't just increase or degrease the temperature. You need to set a heat "ENERGY SAVINGS" setting eg. 55F and "COMFORT" setting eg. 72F and choose between the two over the phone.
    JULIANE -- clovis, CA   10/14/2010
    This is fabulous! Once the thermostat is installed, the installation and setup of the controller takes less than 5 minutes. Being able to control temp at our vacation home remotely means we're able to use the home much more.
    RONALD -- reading, MA   3/5/2010
    Setting this up was really easy it only took 5 minutes. It works great and even if you loose power the unit remembers your program settings even when the power is restored. No need to re-program
    MICHAEL -- westchester, IL   1/31/2010
    It works great. We can call from any telephone and increase/decrease the temperature in our vacation home.
    RICHARD -- bellevue, WA   1/4/2010
    I have not yet been able to solve conflict with answering machine
    TOM -- fountain hills, AZ   11/16/2009
    I really like being able to call and turn on the heat hours before getting to our cold cabin.
    TOM -- austin, TX   6/1/2009
    Works fine.
    DARIN -- long beach, CA   4/27/2009
    Very simple to install basically plug it in and your ready to go. The instructions are easy to follow and works great. I can call with any phone and the controller tells you the current inside temp and gives you your choice of comfort or energy setting
