battery lid carefully, pulling back the strap
with your fingers and lifting the battery lid
towards the top.
Now carefully pull the battery carrier from
its holder and remove the old battery by
pushing it out to the side.
After that you can insert the new battery
into the empty battery carrier, making sure
the positive and negative terminals are
positioned correctly. Then put the battery
carrier back into the holder and latch the lid
of the battery case. Also ensure that the
gasket in the battery lid is in the right
position. Finally please perform a functional
test.
Check window adjustment
In the life of a window influences like wear,
heat and cold may induce a misalignment
of the window fitting. For this reason
window fittings should be controlled and
maintained on an annual basis. On this
occasion, additionally check whether the
distance between the magnet and the
wireless contact is large enough (min. 1
mm, max. 5 mm). If the distance is too small
or the two components collide, the window
fitting must be adjusted in order to avoid
damage to the wireless contact or the
magnet (see illustration
Step 5: Installing
the wireless contact
).
Cleaning
Normally cleaning of the radio contact is not
necessary. However, if you wish to clean its
surface, you can use a dry and soft cloth.
Heavy soiling can be removed by means of
a cloth dampened with lukewarm water.
Please do not use any aggressive or
solvent-containing detergents damaging
the plastic surface of the housing.
8. Possible sources of error
The following section enumerates the most
frequent sources of error of non-functioning
of the radio contact.
Check the battery
The battery can be checked by pressing the
teach-in button and the subsequent signal
via the LED. If no signal is emitted via the
LED, the battery must be replaced.
Check the radio protocol
If several attempts to teach the sensor fail,
please verify whether the subsequent
device or the smart home system is
compatible with the EnOcean radio
protocol. If the devices are compatible,
change the radio protocol and repeat the
teach-in procedure.
Check the radio range
If there is no connection between the radio
contact and the subsequent component or
smart home system, you should check
whether the distance is too big, whether
there are too many obstacles between the
radio contact and the receiver or whether
there are any interference fields. The best
way to do so is to unmount the wireless
contact and check its function in close
proximity to the receiver. If it works in
proximity to the receiver, but not in the
place where it is installed, it is
recommended to use a repeater in order to
increase the radio range.
