## Description

The Thermo Cube is a unique, patented electrical device that plugs into a standard 15 amp electrical outlet and turns power on automatically according to ambient air temperature, saving money by using power only when temperatures require heating or cooling. There are five models available with different temperature ranges to choose from. Each unit has two receptacles for use with more than one electrical dev ice. Cold weather model TC-3 turns on at approximately 35°F, and turns off as temperature rises above 45°F. It is ideal for home and farm applications such as pond de-icers, unheated rooms, pump houses, greenhouses, boats and RV's. One year limited warranty.

Review: Excellent for a heat lamp - Works great for the heat lamp in my exterior well house in the back yard. It saves me from having to keep up with the temp drops in the weather and having to turn the heat lamp on and off. Great quality and price.
Review: Did the job of protecting - Plug it in and be protected. I used this to regulate the heat tape on the hose and main connection point on our RV. It worked as advertised. Having 2 outlets was a real benefit for me.

### ⭐⭐⭐⭐⭐ love it
*by G***Y on January 8, 2011*

when i bought this i was a tad shy because of all the bad reviews and i was also entangled in a bitterness towards seller when i ordered it took several days for them to ship said in stock but it wasnt, after i received the product i realize takes a little gray matter to use it properly, i originally placed it an old style lamp holder you know like grandma used to have thats got a screw in socket with two outlets on the side, but the bulbs heat kept the unit from ever coming on at all, puzzled i finally figured that one out, i put the unit well away from any sources of heat inside my well house and used the 2 outlets one going to a small ceramic heater blowing on my well pump, the other to an extension cord ran outside with a mere childs night light attached, i also purchased a cheap digital thermometer the kind that transmits 100 feet and put receiver inside my home, the week i bought this we had record low temps here well into the low teens, i would check my remote thermometer inside and could see it maintained temp inside well house between 33 and 4o just as advertised , i could also peer out my window and see exactly when unit was operating via the night light placed outside on the extension cord, took me awhile to gain trust in the unit because of all the negative reviews but it works fantastically , i trust the unit has more than paid for itself in less than a month in saved power by maintaining just enough to prevent freezing without having to constantly run a bulb or heater, plus the peace of mind that my well doesnt freeze, i still check my remote thermometer and yep always between 33 and 40 and on really cold nights i can see the little night light come on assuring me its doing its job, i think the people giving the unit bad reviews either got a lemon or maybe not bright enough to use it properly as i did myself originally lol, but i give it A+ works great for me, if mine breaks ill be buying another great product ;-) Adam
