Description - 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 - Together with the BL220F or BL220Fi exhaust air safety switch, forms a safety system for monitoring the differential pressure between the installation room of the fireplace and the connecting piece (chimney) or outside atmosphere during the simultaneous operation of a ventilation system such as an extractor bonnet, hob extractor or living room ventilation system with an open fireplace. Due to possible problematic weather conditions, it is recommended to use an additional BL220Temp (temperature sensor). - Operating voltage: 230 V / 50 Hz - Incl. silicone hose Ø 6 mm, length 2 m Technical data
