Radio shutter (window) contact 1 8250 03
Intended use
This window contact is used to detect when a window is opened. If the window contact is taught-in to a radio energy- saving
controller (see 6), these devices will automatically reduce the temperature in the room during ventilation. Using the automa-
tic temperature reduction function whilst windows are open enables heating costs to be lowered.
The device may only be operated indoors and must be protected from the effects of damp and dust, as well as solar or other
methods of heat radiation. Using the device for any purpose other than what is described in this operating manual does
not fall within the scope of intended use and shall invalidate any warranty or liability. This also applies to any conversion or
modification work. This device is intended for domestic use only.

Preparing for mounting
The window contact consists of two fundamental elem-ents: a magnet (1) and an electronic unit (2).
One of the elements must be mounted on the frame, the other on the window. This ensures that,
when the window is opened, the electronic unit registers that the magnet is no longer in the imme-
diate vicinity and a “window open” signal is transmitted.
Installation location:
• First select the window • that is frequently used for ventilation and which the window contact is to be
attached to.
• The magnet (1) can be installed on the left or right of the electronic unit (2).
• The electronic unit (2) must be attached upright with the release clip (3) at the top.
• The magnet (1) and electronic unit (2) may not be any more than 8 mm (A) apart.
• The magnet (1) and electronic unit (2) must be attached next to one another so that they are level (B).
• The magnet (1) and electronic unit (2) must be positioned so that they are in alignment next to one ano
ther (C).
Mounting
• The magnet (1) and electronic unit (2) may not be any more than 8 mm (A) apart.
• The magnet (1) and electronic unit (2) must be attached next to one another so that they are level (B).
• If necessary, use a pen to mark the bore hole positions (a) for the magnet (1) and electronic unit (2) on
the frame and window.
The magnet (1) and electronic unit (2) can be fastened in two ways:
