Please note: the DFM-1000 is a wireless transmitter. For operation, you need a suitable receiver.
The wireless window contact switch is versatile and can wirelessly switch an optional wireless receiver on and off when approaching the magnet and transmitter part (= window on or close). Freely selectable whether the window is switched OFF or ON and vice versa.
As an exhaust air control, for example, operation of a haze extractor hood is only possible when a window is open, for energy saving with heating and air conditioning systems, operation is only adjustable when the window is closed.
Ideal: with the additional connection option, the radio pulse ON/OFF can also be triggered by external switches.
