Advanced Features for Ultimate Moisture Control
Smart Humidistat
Upgrading to an extractor fan with humidity sensor means automatic protection. When the humidistat detects high humidity in the room, this will trigger the fan to start automatically, regardless of whether the fan is switched on at the wall. This is highly useful where the bathroom might remain humid for a period of time after use.
Adjustable Overrun Timer
A fan with a timer can be set to run after it has been switched off. The adjustable time is from 2 minutes to 30 minutes, meaning that humid air from a bathroom will continue to be extracted after someone has left the room. This design serves both convenience for the user and protection for the bathroom against moisture damage.
Interval Operation Function
For continuous air quality control, the extractor fan runs for 1 hour every 4/8/12/24 hours (adjustment), ensuring efficient ventilation.
