Wireless exhaust air safety switch BL220Fi, built-in version

- Modular radio control system for exhaust air devices
- Enables various customised applications by combining different modules
- Control signals are transmitted in the house by radio - the complex cable routing to individual exhaust air systems (extractor bonnet, living room ventilation system, bathroom fan, etc.) does not need to be installed
- Existing installations can also be easily expanded
- High level of safety thanks to DiBt-certified 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 adapter plug versions.
- Radio frequency: 868 MHz

- For exhaust air systems (extractor bonnets, domestic ventilation systems, fans) that are connected directly to the domestic power supply and where the radio receiver is covered with a metal casing, as is the case with so-called island bonnets, for example.
- With the built-in version, the fan motor can be controlled separately so that, for example, the bonnet lighting can also be used when the window is closed.
- Function:
The BL220FTX radio transmitter monitors the position of the window sash. If the window is open or tilted, the transmitter sends release signals to the radio receiver every 10 seconds and the exhaust air system can run. If the window is closed, no more release signals are sent and the exhaust air system is switched off after approx. 30 seconds.
