Quiet bathroom fan | with humidity sensor / overrun function | Ø 100mm | with exhaust air

T - with follow-up function **
Follow-up time adjustable from approx. 0 min to approx. 30 min.

The off delay can be adjusted using the potentiometer mounted on the electronic system. The minimum delay value is 0 minutes when you turn the potentiometer counterclockwise. To increase the delay time, turn the potentiometer clockwise. The maximum delay value is 30 minutes. The off delay is adjustable continuously. The fan off delay is calculated from the moment the light/separate switch to which the device is connected is turned off.

TH - with humidity sensor and run-on function **
Switch-on humidity adjustable from approx. 60% to 90% relative humidity
Follow-up time adjustable from approx. 0 min to approx. 30 min.

The humidity sensor detects humidity in the range between 60% and 90%. The system is also equipped with a timer. The device's operation depends on how it is connected to the network. In the first case, the fan starts automatically when the humidity level exceeds a set value. It shuts off when the humidity level falls below the set value, as well as after a time specified by the potentiometer, counting from the moment the humidity level decreases. In the second case, in addition to automatic start-up, it is also possible to manually start the fan using the light switch or a dedicated fan switch. After the light or switch is turned off, the device shuts off, as in the first case, after a time specified by the potentiometer.
