Wireless exhaust air safety switch set BL220FiT, built-in version

• Modular wireless control system for exhaust air units
• Enables various desired applications through the combination of different modules.
• Control signals are transmitted wirelessly within the house – the complex cable routing to individual exhaust systems (range hood, living room ventilation system, bathroom fan, etc.) does not need to be installed.
• Even existing installations can be easily expanded.
• High security 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 plug-in versions.
• Radio frequency: 868 MHz

• For exhaust air systems (cooker hoods, residential ventilation systems, fans) that are directly connected to the house network and where the radio receiver is covered with a metal casing, as is the case, for example, with so-called island hoods.
• The combination with the additional exhaust gas sensor allows the extractor hood to be operated without opening the window when the wood-burning stove is not in operation.
• This helps save energy by preventing the window from being opened unnecessarily, thus keeping heat inside the room.
• With the built-in version, the fan motor can be controlled separately, so that, for example, the hood lighting can be used even when the window is closed.
• Function:

However, if the measured temperature in the oven's flue pipe exceeds 40°C, the BL220TEMP will stop sending activation signals. To use the extractor hood again, the window must then be opened so that it can send activation signals again.

• Scope of delivery:
• BL220FiRX radio receiver
• Wireless window contact switch BL220FTX
