Housing easy to clean. The device is equipped with a quiet-running and energy-efficient EC motor. With 5 possible exhaust air connections (3 x DN 125, 1 x DN 125/DN 160) and 1 x DN 160 = predetermined breaking point), with an exhaust air connection DN 125. Motor and electronics are integrated. A maximum of 28 speed levels are possible. Preset as standard to levels 1(a*) = Low, 3(a*) = Normal and 11 (a*) = High. The preset speed levels can be easily changed using DIP switches. With integrated humidity sensor for automatic humidity-dependent control. Wireless remote control ZEG2 EC-FB included in the scope of delivery. = there is characteristic curve a and characteristic curve b, depending on the setting of DIP switch 7, Control: ZEG2 EC-FB wireless remote control with humidity sensor control and 6 setting buttons (humidity sensor is included in the ZEG2 EC). Radio frequency 868.3 MHz. Dimensions (HxWxD): 83x80x28 mm. Protection class: IP 30. LED status indicators. Settings, absence mode (energy-saving mode), automatic mode regulates ventilation level according to the humidity sensor readings, timer mode (15/30/60 minutes) in high level - then last selected level again, 1. low speed - standard position at night, 2. normal speed - standard position during the day, 3. high speed - when cooking and showering, for automatic mode: In this position, the exhaust air appliance runs at low speed until a significant increase in the relative humidity in the exhaust air is measured within 3 minutes (adjustable 5 % or 10 % with DIP switch 7). The appliance then switches from Low (1) to Normal (2) or High (3) depending on the setting of DIP switch 7. If a drop in humidity is detected, the ZEG2 EC runs for 15 or 30 minutes at Normal or High level (run-on time can be set with DIP switch 8). The appliance then switches back to the Low level. For absence mode: The ZEG2 EC runs in energy-saving mode and does not react to the humidity sensor. Installation instructions: The ZEG2 EC-FB remote control can be installed in damp rooms, but not directly in the shower cubicle.
