don't have to rely on everyone to use fan anymore

13 years ago

I purchased this moisture-sensing switch for our bathroom because my wife and kids weren't bothering to use the fan when they showered, and mold was getting to be a concern. I like that it has the option of turning the fan on and off or relying on the sensor, so the fan isn't going whenever the light is on as some commercial bathroom fans are wired. Testing the unit after the simple installation is very easy, you just breathe on it a few times as if you're trying to fog up a mirror. And when I showered after installing the Dew Stop, its LED indicator light and the fan automatically came on about 30 seconds after I turned the water off as the condensation began to visibly settle on the mirror. The fan automatically shuts itself off after 30 minutes.

Yes, I recommend this product.

Questions

Q: Says discontinued. Is there a replacement on the way? Great product but my store is sold out and it's the only one shown online.

10 years ago

1 Answer

A: Unfortunately, there is not a replacement sku as the manufacture is not manufacturing this product anymore. A product that can be used which has some of the same features (not humidity sensing) in that you can set it for a certain time and it will turn off after this time. The product numbers are 52-8841, 52-8858, 52-8860 which have varying set times.

Q: Is this a 3-way switch, compatible with a secondary power wire for the emergency whole-house ventilation

10 years ago

1 Answer

A: The Dew Stop switch can be wired in a 3way application. The stated design, is for Dew Stop to replace the switch that currently operates the existing exhaust fan. Replace that switch with Dew Stop, and your fan will automatically turn on once the room has an increased level of humidity.

Q: If you manually turn off the dew stop while it is running due to high levels of humidity, will it stay off? I need it to stay off for five minutes. After this, I want to be able to manually turn the fan back on. Thanks

11 years ago

1 Answer

A: You can manually turn the Dew Stop switch off during a cycle when it has sensed excess humility. But, if moisture is still detected the unit will turn on again. If moisture is not detected it will remain off.

Q: Est-ce qu'il est ajustable ? J'ai besoin de savoir si ce dispositif comporte des ajustements tel que : - Le % d'humidité auquel il va démarrer. - Le temps de fonctionnement. Merci !

A: Un peu tard mais bon peut-être que d'autre personne se pose les même questions.. Non il n'est pas ajustable mais est quand même relativement sensible. Le temp de fonctionnement est de 30 minutes, pas ajustable non plu mais on peut l'arrêter manuellement au besoin. Beaucoup de renseignement sur leur site web: http://www.dewstop.com
