Extractor hood and window contact. May only be switched on when the window is open.
A window contact is required if you have an extractor hood and a fireplace or other fireplace in your apartment or house. The use of a fireplace and an extractor hood in exhaust air mode at the same time is not permitted without a window contact. The door and window contact prevents the hood motor from starting up when the window is closed. The extractor hood only works when the window is open. This prevents negative pressure from building up and spreading toxic gases or carbon monoxide in the room.
For this application, you need a Smart door and window contact and a Smart plug
Plug the extractor hood into the smart adapter plug and then register the door/window contact on the adapter plug.
That was all. When the window is open or tilted, the adapter plug and thus the extractor hood switches on. When the window is closed, the voltage is or remains switched off.
