Please note that this is only the window contact. The wireless window contact transmits window open or window closed information to the INSTAT 868-a1Up wireless receiver. When a window is opened, the output is switched off immediately. When all windows are closed again, the relay is switched on again with the next on signal. After 30 minutes at the latest, the control continues as normal, even if windows are still open. (Window was forgotten to be closed, the room must be protected from frost). Up to 10 window contacts can be taught.
