Dimensions and technical data: 100-240 V ~ 50/60 Hz; Housing color: black; Housing material: UV-resistant plastic; Nominal diameter: 100 mm; Bearings: ball bearings; Speed ​​settings: 5; Power consumption: 0.4 / 0.6 / 0.8 / 1.6 / 2.7 W; Current consumption: 0.018 / 0.019 / 0.021 / 0.029 / 0.038 A; Airflow: 20 / 40 / 60 / 90 / 115 m³/h; Sound pressure level Lp-3m: 9 / 13 / 18 / 22 / 27 dB(A); Protection class: IP44; Housing diameter: 193 mm; Connection diameter: 100 mm; Depth: 55 mm; Overall depth: 81 mm; Weight: 0.5 kg; Integrated Overheating protection. Mounting options: wall, ceiling. Intermittent or permanent ventilation of bathrooms, showers, kitchens, and other living spaces. Operating mode 1: Continuous ventilation at speed 1; changes to speed 3 when the motion/light sensor is triggered; changes to speed 4 when the humidity sensor is triggered. Operating mode 2: Continuous ventilation at speed 2; changes to speed 3 when the motion/light sensor is triggered; changes to speed 4 when the humidity sensor is triggered. Operating mode 3: Continuous ventilation at speed 2; changes to speed 5 when the humidity sensor is triggered. Operating mode 4: Continuous ventilation at speed 3; changes to speed 5 when the humidity sensor is triggered. Operating mode 5: Standby operation; changes to speed 3 when the motion/light sensor is triggered; changes to speed 4 when the humidity sensor is triggered. Operating mode 6: Intermittent ventilation (30 minutes every 12 hours) at speed 1; When the motion/light sensor is triggered, the speed changes to 3; when the humidity sensor is triggered, it changes to 4. Operating mode 7: Standby mode; when the temperature sensor is triggered, it changes to speed 4. It switches on at 28°C in the room and off at 24°C. Operating mode 8: Standby mode; when the humidity sensor is triggered, it changes to speed 5. If one or more sensors are triggered, the fan switches to high speed and runs until the sensor signal disappears. After the sensor signal disappears, the fan continues to run at high speed for 15 minutes and then switches to standard operation. If a motion or light sensor is triggered, the fan switches to high speed with a 30-second delay to prevent it from switching on during a brief stay in the room.
