How it works

After the lighting or switch is turned off, the fan continues running for the set run-on time and reliably removes residual moisture from the room. In the TH model, humidity is also monitored continuously, and the fan is automatically activated or deactivated as needed. This effectively helps prevent mold growth and supports a consistently comfortable indoor climate.

• Run-on time is set by turning the potentiometer
• Clockwise: longer run time, counterclockwise: shorter run time
• Humidity sensor operates in the range of 60 % to 90 % relative humidity
• Suitable for installation in standardized ventilation systems
