I) Deleting door/window contact sensors
Door/window contact sensors that are no longer required or are no longer in operation should
be deleted in order to avoid repeated error messages from being displayed (‘reception failure’).
The power consumption also increases as attempts are regularly made to receive signals from
the door/window contact sensors.
Proceed as follows to delete a door/window contact sensor:
• Press the ‘
