Essential Info

Automate your hot water heating system to work when you want it to, no matter what day it is! Unlike other thermostats that limit you to one weekday schedule and one weekend schedule, this versatile thermostat allows you to choose a different schedule for every day of the week. Select times and temperatures that best suit your family and you won't need to run the heater all day long when no one's home!


What's Included

  • 1x - Thermostat
  • 1x - Manual

  • More Info

    Program the thermostat to leave the heat on for your housekeeper on Thursdays, or turn the heat off from 10 a.m. to 2 p.m. on Sundays while you're visiting Grandma. Simply program two different temperatures: comfort and economy. Then choose four different program times each day, and your house will set itself to the comfort or economy temperature for waking up, leaving the house in the morning, returning home, and going to sleep. Simple push-button programming gets you going in just a few minutes. Plus, you'll still have full manual control any time you decide to make an adjustment! There's also a vacation mode setting for when the house will be unoccupied for an extended period, and when it's time to leave for vacation, a single press of a button will set your heating system to vacation mode. Once you're back home another single button press will put your system back on its normal schedule.

    The Hot Water Heating Systems Thermostat is loaded with features, including 12- or 24-hour display, temperature display in Celsius or Fahrenheit, and adjustable regulation cycles from 5 to 20 minutes. During warmer months, the thermostat will start the system once a day to keep the water pump from seizing. It also reduces wear and tear on your heating equipment by preventing short-run cycles and forcing the system to rest for 10% of the last run time before starting up again.

    For remote activation, add a telephone controller (sold separately), and you can warm your vacation home just hours before you arrive! You can also program the system to switch into or out of vacation mode automatically with any home automation controller or security system that can provide 12 volts DC.

    This thermostat is compatible with all hot water heating systems, hot air systems with no ventilation control, MilliVolt systems, and electrical heating systems with relay.

    We use these thermostats on our three zone hot water heat system. They are fantastic! Even heat throughout the 3000 sq' two story home.
    RICK -- farmington, NM   4/11/2013
    Fantastic product. We use these thermostats on our three zone baseboard hot water system and our home now has even heat throughout. Great price too. Thanks SMARTHOME.
    KENNETH G. -- moab, UT   1/8/2013
    Works very well with radiant hot water heating. The control circuit learns the characteristics of your particular system and heats accordingly. No more wild temperature swings like happened with the standard thermostat. Also love the pump saver feature that exercises the circulation pump one minute a day to keep it from freezing up.
    FRANK -- prairie village, KS   1/23/2012
    Totally resolved temperature control issues with circulating hot water heating system. Excellent system.
    Russ B -- chesterton, Indiana   12/22/2011
    I replaced a basic generic thermostat for my hot water system. The improvement was dramatic. No more too hot then too cold. HVAC contractor had circulating pumps running 24/7. I especially like the pump on each dat during the summary since I previously had a pump seize. Replacement cost was greater than the Aube TH-140. I could not find anything else in the US short of a PLC that could do what this does.
    BRUCE -- fort erie, ON   11/13/2011
    Specific for hot water systems, all the other high tech thermostat just dont work as well
    ALAN -- loveland, CO   6/22/2011
    Seem to function properly. Haven't used the thermostats that much yet since it is summer. I like the thermostat a lot. Thanks!
    MICHAEL -- boxborough, MA   6/9/2011
    this is the second one I bought. It is great an allows me to call my home and turn up the heat. I love it
    KAAS -- ashland, WI   11/26/2010
    We liked the first five we bought so much we ordered an extra one afterward so we could use the same one when we add a zone next year.
    KAAS -- ashland, WI   11/1/2010
    We really love our five new Aube TH140-28-01 units. We are pretty technical and installed them ourselves, so the sale price made them a great investment especially as our old thermostats were neither programmable nor hot-water-heat specific! The thermostat does make a loud CLICK when switching that some people might not like. Not really an issue for us. We plan to buy 1 more unit to hold onto for a future additional heating zone.
    ROBERT -- rochester, MN   1/15/2010
    easy to install and works as advertised
    RJC -- coeur d'alene, ID   10/29/2009
    The Thermostat works fine but the LCD fails in less than 2 years. With just parts of the LCD working it is a guess on what you are setting the temperature at. I bought 6 and 5 of the units provide a great guessing game around the house.
    SERGIO -- miami, FL   5/15/2009
    Excellent product. It was very easy to install and I have it working in no time.
    DOUGLAS -- wethersfield, CT   1/31/2009
    This is an incredible thermostat. We have ancient Victorian radiators in our home. This thermostat keeps the temperature steady. The only negative comment I have is the type on the thermostat on how to reset it is too small to read and the paper with instructions on it is easy to lose.
    PHILIP -- sudbury, MA   12/1/2008
    The vacation mode and the ability to turn it off by flashing it with a 12v signal makes this an excellent vacation home thermostat at a fraction of insteon thermostat price.
    JAY -- east northport, NY   11/28/2008
    Worst product ever - clock keeps resetting so programming is unusuable
    DONALD S. -- glen cove, ME   11/7/2008
    Great for gas fireplaces that use the MV system. I have three of these in my home (2 for 4 years) and each works great and are easy to program and easy to change the batteries too.
    CHARLES -- foster city, CA   11/6/2008
    Easy to install. Good instructions. Only shortcoming is that thermostat does not have an "off" setting. Therefore the system is always "on" in one of three programmed modes(comfort, economy, or vacation)
    FERNANDO -- west newton, MA   3/23/2008
    A good basic thermostat. Somewhat audible click when it switches.
    ARNIE -- pecatonica, IL   1/5/2008
    Works great. Had trouble programing. Hard to understand directions. After I figured it out, works fine.
