Due to the stove, sucks the air from the outside, we were told we do not need a toggle switch for the extractor in the new building. The chimney sweep saw that but otherwise ... what now? Saw myself aufhauen the walls, laid cable shafts. Then I came up with this device. Ordered, connected the transmitter to the window and the subject was already done! There are nearly 100 again a joke ... But even those who want to install everything I can firmly recommend the radio variant. We had several windows to choose from, where the transmitter could be fixed. The selected I can now change at any time. The unit is now running for about a year without problems! (Only the chimney sweeper no longer asked whether we have upgraded what ...)
