Frequently Asked Questions
What does a humidity switch do?
What does a humidity switch do?
A humidity switch monitors the moisture level in the air and automatically turns on a ventilation fan when it detects high humidity, then turns it off once the air has cleared.
Where should I install a humidity sensor switch?
Where should I install a humidity sensor switch?
They are most effective in bathrooms, laundry rooms, home spas, and basements—anywhere prone to condensation, dampness, or mold growth.
Will the fan turn on every time it rains?
Will the fan turn on every time it rains?
Not if you have a high-quality humidity sensor switch. Modern sensors use "rate-of-rise" technology to distinguish between the fast moisture increase of a shower and the slow, natural increase of a rainy day.
Can I manually turn the fan on?
Can I manually turn the fan on?
Yes. Every humidity switch includes a manual override button. If you need immediate ventilation for odors, you can press the button to run the fan for a set "timeout" period.
How long does the fan stay on?
How long does the fan stay on?
This is determined by your "Time Delay" setting. Most switches allow you to choose between 10, 20, 30, or 45 minutes. The fan will run for this duration or until the humidity drops below your set threshold.
