The DewStop FS-100 Condensation Sentry Fan Switch is ideal for preventing the growth of mold and mildew created by condensation from baths and showers. The switch features a clever sensor that constantly monitors temperature, humidity, and dew point and automatically turns on your fan when the air becomes too heavy. Once a room's condensation level is brought down, the sensor will trigger the fan to turn off. You can rely on the sensor to work automatically, or you can manually control your fan with the button located on the switch. For those times when you choose to turn the fan on yourself, a 30-minute fan timer will automatically turn it off to help you save money and electricity.

Save on Energy and Maintenance Costs
Using an exhaust fan to rid a bathroom of humidity can be a tricky balancing act. Turn it off too soon, and you may leave behind damaging moisture. Leave it on too long, and you waste energy by sending heated or cooled air outside unnecessarily. Because the DewStop only comes on when needed and stops after 30 minutes, it helps you save on home maintenance and energy costs.

Make Your Fan a Smart Fan
With the DewStop Condensation Sentry Fan Switch, you can transform your bathroom from ordinary to intelligent. This clever switch features a "Condensation Sentry", which constantly monitor's temperature, humidity, and dew point to determine a room's condensation level. If the sensor detects rising condensation levels, it will automatically turn on your fan and keep it on until the condensation is no longer a concern and your room is dry.

Automatic or Manual Fan Control
You can rely on the DewStop Condensation Sentry Fan Switch's sensor to control condensation for you, or you can manually turn on your fan when needed--a built-in timer will turn the fan off after 30 minutes, or you can turn the fan off yourself before the time is up.

Perfect for Bathrooms, Laundry Rooms, and Home Spas
The DewStop Condensation Sentry Fan Switch is great for use in bathrooms, laundry rooms, sun rooms, spa rooms, and all condensation-prone areas of the home. Packaged as a single fan switch that's easy to install, this unique device can be connected with any residential fan you care to use.

NOTE: A closed room and quality fan properly sized for the room is essential to the successful removal of moisture. DewStop only detects condensation, it cannot stop it.

Easy Installation
Whether your fan is controlled by a timer or toggle, you'll have no trouble removing its switch and replacing it with DewStop. DewStop's size and shape are the same as a rocker switch, so it will fit right into your existing single-switch position. DewStop comes with a decor/rocker single-position color-matching faceplate, but it can be used with a faceplate of any color or configuration designed for a rocker-type light switch.

Prevents Mold, Mildew, and Expensive Repairs
Mold needs moisture and time to grow. If left unchecked, it can get into walls and cause costly cosmetic, health, and structural problems. That's why the DewStop Condensation Sentry Fan Switch ensures your room is never left damp, so mold has little chance to grow. DewStop does this by detecting moisture and running your fan long enough to dry out a damp environment. This greatly reduces the formation of mold, mildew, and harmful bacteria and saves you from expensive repairs.

The DewStop Condensation Sentry Fan Switch is UL certified. It has an electrical input of 120 volts and a maximum fan load of 3 amps.

From the Manufacturer

DewStop is intended for use in condensation problem areas of a home, such as near the shower or bath. If condensation is a problem or suspected to be a problem, simply replace your existing fan switch with the DewStop Fan Switch. For DewStop to sense dew (condensation), the room will need to show visible signs of wetness attaching to the surfaces, such as steam on walls, mirrors or fixtures. Visible steam in the air is not the problem, the problem occurs when moisture in the air becomes too heavy and the air cannot support the moisture. The moisture then moves to surfaces (this is the dew point), triggering the DewStop sensors. The remarkable DewStop fan switch is constantly checking the air for condensation. At the right time, DewStop will turn on your fan and run the fan to clear the room. After the room is clear of moisture, DewStop turns off your fan. Your fan can also be manually operated at any time. This model is for use with any residential fan. The Patent Pending sensor "Condensation Sentry" is at the top. The middle button turns on the fan and the bottom button turns off the fan manually. The sensor needs no maintenance and provides a lifetime of use. The DewStop Fan Switch helps prevent costly repairs due to the growth of mold or bacteria by monitoring and controlling condensation. The DewStop Fan Switch is UL certified. The electrical input is 120 volts and the maximum fan load is 3 amps. The DewStop Fan Switch is great for use in bathrooms, laundry rooms, sun rooms, spa rooms and all condensation areas of the home.
