• Modular radio control system for exhaust air devices • Enables various desired applications through the combination of different modules • Control signals are transmitted wirelessly within the house – there is no need to install complex cabling to individual exhaust air systems (extractor hood, living space ventilation system, bathroom fan, etc.). • Existing installations can also be easily expanded • High level of safety thanks to DiBt e modules • Various radio transmitters, such as window contact switches, temperature sensors and pressure monitors, can be conveniently combined with various receivers, such as built-in or plug-in versions. • Radio frequency: 868 MHz• For exhaust air systems (extractor hoods, living space ventilation systems, fans, etc.) that are connected to the domestic power supply with a Schuko plug and where the radio switch (receiver) is covered with a metal casing, as is the case with so-called island hoods, for example. • Function: The BL220FTX radio transmitter monitors the position of the window sash. When the window is open or tilted, the transmitter sends activation signals to the radio receiver every 10 seconds and the exhaust air system can run. When the window is closed, no more activation signals are sent and the exhaust air system is switched off after a run-on time of approx. 30 seconds. • Technical data: - Maximum switching capacity: 5 A / 1150 W - Operating voltage: 230 V / 50 Hz Schuko plug - Power consumption: 3 W • Scope of delivery: - BL220FRX radio receiver - BL220FTX wireless window contact switch
