Humidity Detection This humidity wall switch works by detecting the levels of moisture in the air and turning the fan on when humidity is high. The fan will turn off again after 30 minutes or when humidity levels return to normal, whichever comes first.

Manual Operation Don’t want to wait for the humidity sensor switch to activate? The TDHS5-N also features a manual ON/OFF button that allows you to bypass the humidity sensor whenever you like. Simply press the button to turn the ventilation fan on or off at any time.

Prevent Mold Stagnant humidity causes mold and mildew to develop. This is not just a problem for bathrooms, but for spas, laundry rooms, fitness centers, locker rooms, and more! A humidity wall switch keeps the moisture levels in check to prevent such microbial nuisances.

Promote Safety Ventilation fans can overheat when left on, especially if they are clogged with lint and dust, and this can cause fires if left unattended. An automatic humidity switch ensures that the bathroom fan is only used when needed and that it is never left on by mistake.
