Need an inexpensive and simple thermostat? Thermo Cube thermostatic outlets are the answer. These unique devices plug into a standard electrical outlet and have an internal preset thermostat. Outlets come in two models. The Cooling outlet (Model TC-21) supplies power at 78° and cuts off at 70° and works great for all types of fans including exhaust, circulation, window, attic, and ceiling fans. The Heating outlet (Model TC-3) supplies power at 35° and cuts off at 45° and is great for automating heaters to keep room temperatures above freezing. Each outlet has two receptacles and can be used with 110/120 volt outlets and appliances. The maximum load for both receptacles combined is 15 amps.
