The Condensation Sensor Plus is the next generation in moisture control and healthy indoor air technology. Condensation Sensor Plus works with any single speed vent fan, automatically turning the fan 'on' before condensation forms, and off when the room returns to the optimum dryness level. Unlike competitive units that only monitor humidity levels, the Condensation Sensor Plus features advanced, built-in intelligence that monitors both temperature and humidity - actually anticipating the dew point - making it the most effective, proactive solution on the market. Additional features include a blue LED light to indicate when the fan is on and a matching wall plate for a decora style design. Can be used to comply with ASHRAE 62.2, LEED, CALGreen and ENERGY STAR 3.0.
