The Enerlites DWHS is a humidity sensor wall switch that can automatically operate a ventilation fan based on the moisture levels in the air. When humidity is high, the fan will automatically turn ON, and it will turn OFF again when moisture levels have returned to normal. This feature is designed to eliminate condensation and prevent the development of mildew and mold in damp areas such as bathrooms, spas, or locker rooms. Monitoring moisture levels with a humidity sensor helps to maintain a clean, safe and comfortable space. This switch is compatible with incandescent, fluorescent, halogen, and LED lights. 

This device also features an interchangeable face cover that can be replaced with alternative colors (sold separately). DWHS-L (Black and Light Almond).
