Radio shutter (window) contact
ETH comfort
Operating Manual
1. Intended use
This window contact is used to detect when a window is
opened. If the window contact is taught-in to radio electronic
thermostats (see 6), these devices will automatically reduce
the temperature in the room during ventilation. Using the au-
tomatic temperature reduction function whilst windows are
open enables heating costs to be lowered.
The device may only be operated indoors and must be pro-
tected 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 man-
ual 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.
2. Overview
3. Preparing for installation
The window contact consists of two fun-
damental 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 immediate vicinity and a “window
open” signal is transmitted.
Installation location:
First select the window that is frequently
•
used for ventilation and which the win-
dow 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 at-
•
tached upright with the release clip
(3) at the top.
Distances:
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 another (C).
4. Installation
Use the wall brackets for the elec-
•
tronic unit (2) and magnet (1) to
align them.
If necessary, use a pen to mark the
•
bore hole positions (a) for the mag-
net (1) and electronic unit (2) on the
frame and window.
•
The magnet (1) and electronic unit (2) can be fastened in
two ways:
Adhesive strip method
This does not damage the door or
•
window in any way.
Use the adhesive strips supplied.
•
Stick the strips on the rear sides of
•
the brackets (1 and 2).
Then press the brackets onto the
•
frame and window.
Screw method
If you are working with a hard surface, you should drill
•
the holes marked (a) using a 1.5 mm drill.
Use the countersunk head screws supplied to fasten
•
the electronic unit (2).
Once fastened, the magnet (3) can be inserted in the mag-
•
net bracket (1). Then place the cap on the magnet.
Using screws will damage the frame and/or window.
For those living in rented accommodation, this could
lead to a landlord making a claim for compensation
or holding back a tenant’s deposit.
5. Inserting (replacing) batteries
The window contact is operated with 2 LR03 (Micro/AAA)
batteries.
Push the release clip (1) backwards.
•
Pull the upper part of the device up
•
and at an angle (2), and remove it
from the bracket.
Insert 2 new micro batteries (LR03/
•
AAA) in the battery compartment (3)
of the upper part (making sure they
are the right way round).
Place the upper part back onto the
•
bracket, allowing it to latch into
place.
The service life of new alkaline batter-
ies is approximately 5 years, based on
opening the window twice a day for two hours at a time.
If the LED flashes three times when the window is opened
or closed, this indicates that the batteries need to be
replaced.
Never recharge standard batteries. Doing so will
present a risk of explosion.
Do not throw the batteries into a fire.
Do not short-circuit batteries.
Used batteries should not be disposed
of with regular domestic waste. Instead,
they should be taken to your local battery
disposal point.
6. Teaching-in to radio components
To enable radio components to communicate with one
another, they need to be taught-in to one another. The window
contact can be taught-in to system components such as a
radio electronic thermostat.
The first step is to switch the receiver) to teach-in mode.
•
For information on how to do this, please refer to the ope-
rating manual for the relevant device.
Following this, the window contact needs to transmit a
•
signal for teaching-in purposes. To initiate this, open or
close the window.
If the window contact has not yet been installed, you
•
can simply separate the magnet and electronic unit or
rest them against one another. However, please note
that the batteries must already have been inserted in
order to do this.
When a signal is transmitted, the window contact LED
•
lights up.
A window contact can be taught-in to any number of ac-
tuators.
7. LED flashing sequences & transmission behaviour
The LED’s flashing sequences have different meanings:
Flashing sequence
Meaning
1x flash
Contact/window closed
2x flashes
Contact/window open
3x flashes
Replace batteries
If, whilst a signal is being transmitted (after the win-
dow has been opened or closed), the window contact
detects that the battery power is too low, the LED will
emit the “replace batteries” flashing sequence once the
signal has finished transmitting.
After a window has opened or closed, the window con-
tact transmits a signal for 5 seconds. Any further chan-
ges that are attempted while the signal is being transmit-
ted will not provoke a response. However, if the position
has been changed during this time, the new status will be
transmitted directly afterwards and indicated by an LED
flashing sequence.
8. Information on radio operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possibility
of interference occurring. Switching operations, electric
motors or faulty electric devices are some of the reasons
why interference may occur.
The range of transmission within buildings can deviate
greatly from open air distances. Besides the transmitting
power and the reception characteristics of the receiver,
environmental influences such as humidity in the vicinity
and structures also play an important role.
ELV Elektronik AG hereby declares that this device con-
forms with the essential requirements and other relevant
regulations of Directive 1999/5/EC. The full declaration of
conformity is provided at www.elv.de.
9. Safety instructions
These devices are not toys: do not allow children to play
with them. Do not leave packaging material lying around,
as this can be dangerous in the hands of a child.
Do not open the device: it does not contain any compon-
ents that need to be serviced by the user. In the event of
an error, please return the device to the service department.
10. Disposal instructions
Do not dispose of the device with regular domestic
waste.
Electronic devices must be disposed of in ac-
cordance with the Waste Electrical and Electronic
Equipment Directive via local disposal points for
electronic waste.
The CE sign is a free trade sign addressed exclu-
sively to the authorities and does not warrant any
properties.
