Essential Info

Plug your appliance into the cold weather Thermo Cube and plug it into the wall. When the temperature drops below 20° the Thermo Cube will turn your appliance ON. When the temperatures 30° or greater it will turn your appliance OFF. Each unit has two receptacles for use with more than one device to operate loads up to 1800 Watts, 15 Amps, 120VAC. The Thermo Cube is also available with different temperature ranges to suit your specific needs. It is recommended that the Thermo Cube is used with GFCI outlets.


What's Included

  • 1x - Thermo Cube - 20° ON/30° OFF
  • More Info

    Use this Thermo Cube to automate self-regulating heat tape, heat lamps, stock tank heaters, pond de-icers, engine-block heaters. If it gets too cold in the attic because the pilot light blew out when gas service was interrupted, you can have it turn on a space heater. You can even use the Thermo Cube with a strobe light to create a "Freeze Warning" system that can be seen by neighboring homes or buildings.

    BYRON -- mount airy, MD   1/10/2013
    Works as advertised. Would prefer weatherproof and sightly higher range (on at 28 off at 35) for heat lamps.
    CHARLES -- moriarty, NM   12/30/2012
    Love this item. Just a note: cube shuts off at 30 degrees, otherwise if temp is lower it is on...even below 20. I use this with a 250W heat lamp.
    BILL -- spring valley, CA   3/7/2012
    This is an excellent product at a reasonable cost that will save me a lot of money on electrical bills. Thank you, Bill Saumier
    DENNIS -- landis, SK   3/1/2012
    Product is as advertised, works satisfactorily and was a good value (sale item). Would have preferred a weatherproof unit since the it is controlling an outdoor water trough heater. Particularly happy with the prompt service.
    DONALD -- gainesville, VA   1/14/2012
    Works well, I used it on the bubbler for my boat. When the tempreture goes below 20 the bubbler comes on and keeps the water moving around the boat. Above freezing it turns off saving electricity.
    ALLAN -- manorville, NY   2/24/2011
    on time and what I needed.
    PAUL -- bowmanville, ON   1/15/2011
    Just started using these cubes. Simply plug into your extension cord and they manage the rest. Currently keeping my water pipes from freezing as I have a trouble light plugged into the cube.
    JILL -- winnemucca, NV   1/3/2011
    The cube blew the breaker in our house every time we tried to use it. My Mom has one and it works fine so I am not sure why ours does what it does.
    HOWARD -- massapequa, NY   1/22/2010
    does not always go on @ 20. stays off too much
    PETER D -- burlington, ON   1/5/2010

    I have not used it yet. But plan on implementing later this year.
    ARTHUR -- rapid city, SD   2/15/2007
    Great product - simple, intuitive, easy to use. But needs label with both off and on temps.
    SCOTT -- wheeling, WV   12/11/2006
