About This Product

The Thermo Cube is a patented, temperature-sensitive electrical device that plugs into a standard 15-amp outlet and automatically powers connected devices based on outdoor air temperature. Designed to conserve energy, it activates only when heating or cooling is necessary. This model, TC-3, is specifically built for cold weather conditions—it switches on at 35°F and off at 45°F.

With two built-in receptacles, the Thermo Cube allows you to connect multiple electrical devices at once. It’s ideal for both residential and agricultural use, including applications like pond de-icers, pump houses, greenhouses, unheated rooms, boats, and RVs.
