Wireless extractor fan controller, fitted version
When using the FDS 100 wireless extractor fan controller, an extraction system can only be used when the window is open and the required supply of air can flow into the room. A contact system monitors the position of the window sash and wirelessly sends the status to the receiver.

The receiver is installed in the extraction system and only operates the extractor fan. The lighting also works with the window closed.
The FeuV (Feuerungsverordnung — German fire precautions regulation) (§ 4, Installing heat-producing appliances) stipulates: If a heat-producing appliance dependent on ambient air (e.g. gas-fired boiler, a firewood stove) and an extractor fan (e.g. extractor hood) are operated simultaneously, it must be ensured in a place of residence/house that no carbon monoxide is extracted from the heat-producing appliance. As soon as an extractor system is switched on, a vacuum is created in a closed room. The pressure must only be equalised via the flow of fresh air from the outside and not via the heat-producing appliance.
