## 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: 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.
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.
