Leviton's Combination Single Pole Humidity Sensor and Fan Controller with Light
Switch senses the humidity of your bathroom and turns your bath fan or fan/light ON
when the humidity gets too high. This reduces condensation in your bathroom and
increases ventilation when used in other household spaces.
• Compatible with Incandescent, LED, CFL, and ELV/MLV loads
• Sensitivity adjustment.
• Built-in countdown timer feature for manual operation.
• Automatic ventilation/air circulate mode for continuous operation, with hourly
preset time-outs.
• With Zero Cross turn-ON technology to extend the life of switching relays.
• Advanced sensing enhances detection when the room is occupied and minimizes
false triggers when unoccupied.
• Color change kits available in white, light almond, ivory, black, brown, and gray.
For bathroom applications, the device should be placed at a level that can detect
steam. Placing the detector directly above a heater or near drafts is
NOT recommended.
NOTE: DO NOT use to control a fan/light combination where the fan/light is the only
means of illumination.
NOTE: The Humidity Sensor and Fan Control will not eliminate condensation and
must be used with a properly sized ventilation fan in an enclosed space.
