Overview
2018-04-11 Page 3 of 18
The Enertex®-ProxyTouch KNX is a capacitive touch sensor that can be installed behind
surfaces such as ceramic, wood and glass. It has three sensor areas (see Figure 7) that can be
flexibly adapted to the preferences of the user:
Basic features
•The sensors can be addressed together,
•individually,
•or by slide gestures.
•For individual sensors also a double click is applicable for each sensor area.
•If the slide gesture is set, the 3 sensor areas can be additionally addressed by a double
click and as a single common button.
Feedback
If you touch the tile, behind which the device was mounted, at the desired sensor area (A, B or
C), so a message is written to the bus. After contact (parametrizable) an audible feedback is
given, which at each panel has a different pitch (A=high, B=medium, C=low). If the back of the
device is available, a light up of orange LEDs below the respective sensor area can be seen
when touching the control panel. If the device is in programming mode, a red LED is visible and
an acoustic signal is given. The volume of the acoustic signal can be changed in three stages.
Cleaning operation
In the device a cleaning operation mode can be activated via the group object (KNX message).
When this is active and an operation/trigger of the sensors is done by the user, so no messages
are triggered and parametrizable an acoustic signal is generated. The cleaning operation mode
can be canceled by itself parametrized via a time constant up to max. 3h.
Application
Since the sensors react to changes in the surrounding electric field, the functionality of the
ProxyTouch KNX is better given at a rapid approach than at a slow. In addition, the surface of
the material has to be really touched to excite the sensor. Wiping or approaching without contact
does not lead to tripping. By using double click it has to be ensured that the complete gesture
was really led away from the sensor and back to it again. A simple quick tap with your finger, as
usual from the computer mouse operation, is not sufficient.
Commissioning
Supply
For the operation of the Enertex® ProxyTouch KNX an external voltage supply is not needed.
The device gets the supply voltage from the bus.

the KNX connection cable of the sensor may be connected to the protective earth of the
building to increase the sensitivity. Thereby, the KNX bus is capacitively coupled to the
protective earth.
Application
•The magnetic switch button at the bottom right sets the ProxyTouch into the
programming mode.
The Enertex® ProxyTouch KNX can be mounted behind several materials with different
thicknesses.
MaterialMax. recommended material thickness
Tile25 mm
Wood 20 mm
Glass25 mm
To ensure the functionality completely, the maximum material thicknesses must be noted. It may
be also necessary to connect the white conductor in the KNX connection cable of the sensor to
the protective ground of the building. Thereby, the KNX bus is capacitively coupled to the
protective earth.
The Enertex®-ProxyTouch can be installed in wet rooms. Direct water jet is to be avoided. It is
recommended that the mounting position in wet rooms is so configured that splash from the
biggest person hits the sensors as little as possible. In the next Figure 2, the shower head is at
height of 1.95 meters, thus the striped area due to the angle of radiation is not recommended
for mounting:

2018-04-11 Page 5 of 18
Figure 2: Installing position in wet rooms
The robustness of the ProxyTouch decreases with increasing water amount reacting on the
surface. In contrast to the direct reaction of a water jet, low splashing and water vapor do not
result to false tripping. The robustness of the ProxyTouch is substantially increased when in wet
rooms the button partitioning “Slide gestures” is applied and the sensor areas are only
configured as double click.
At this point it is again referenced to the application described above:
Since the sensors react to changes in the surrounding electric field, the functionality of the
ProxyTouch is better at a rapid approach than at a slow. Furthermore the surface of the material
has to be really touched to excite the sensor. Wiping without contact does not lead to tripping. At
double click it has to be ensured that the complete gesture was led away from the sensor and
back to it again. A simple quick tap with your finger, as usual from the computer mouse
operation, is not sufficient.
Fitting & installing instructions
A correct installation is fundamental for Enertex® ProxyTouch KNX to work as designed, and
depends on its operation area. It must also be ensured that the ProxyTouch KNX lies as flat as
possible on the back, that is it should be avoided, that an “air” distance is formed between the
back of the desired surface and the ProxyTouch KNX. A possible distance between the
mounting material and the sensor reduce the sensor range. In particular, “air” between the two
dampens the range by factor by factor 3 to 4 which means that 2mm air between sensor and
back side of mounting location corresponds to a 6 to 8 mm range shortening.
During installation, pay attention to maintenance access. Claims for damages for
consequential damages due to dismounting is not granted and is excluded.
Default No waterproofing
The Enertex® ProxyTouch KNX is each aligned and fixed on the back of the desired surface. In
case of tiles, plastic and glass the housing is glued to the edges using the enclosed adhesive.
For wood the housing has additional holes at the corners, through which the housing can be
screwed together with screws. With the use of the mounting adhesive the housing must be
placed and fixed on the intended place of the material to prevent slippage during the bonding
operation (Figure 3). It must be ensured that the adhesive surface is clean, dry and free of dust
and grease.

Figure 3: Fixing the housing
If so, the mounting adhesive can laterally be applied 5mm high in the corner between housing
and material.
Figure 4: Applying the adhesive mounting
To obtain a clean glue line, the applied mounting adhesive is spread.
Figure 5: Spreading the mounting adhesive
After the three easily accessible sides have been glued, the fixing can be untightened and the
last side can be bonded. While curing, the mounting should be weighted down to ensure a very
dense contact pressure at the surface. After about 6-8 hours the adhesive is so far cured that
the tile can be plugged. After 24 hours the adhesive is fully cured.

With waterproofing e.g. in showers
If the operation area is regularily exposed to water, waterproofing may be required. Please
consult IBC chapter 27 or Tile Council of North America (TCNA) publications, e.g., TCNA
Handbook for Ceramic, Glass, and Stone Tile Installation for detailed instructions. To maintain a
waterproof sealing of the underground construction, Figure 6 recommends two installation
options. The ProxyTouch KNX may be installed on or below the waterproof membrane. It
depends on the detailed conditions, which one is better suited. Please note the recommended
material thicknesses mentioned above is 25mm for tiles.

Software description
Programming
The device is programmed via the ETS. By the enclosed magnet the device can be set, even
after installation, into the programming mode. For this purpose the magnet is swept over the
surface behind which the device is located. The activation switch is located in the upper left
corner of the device and thus in the upper right corner of the surface. Once the device is in
programming mode an audible signal (buzz) can be clearly heard. If the device has not yet been
installed, a visual feedback (red LED) is also visible besides the audible signal.
Button partitioning
According to the parameterization up to four different messages can be transmitted to the KNX
bus via the touch panels. Each panel gives an audible feedback when touched. Thereby the
sound output varies from high (A) to deep (C). In the button partitioning “Slide gestures” and the
function double click an even higher tone than in single button is emitted in case of successful
operation.
The panel is divided into a maximum of three different sensor areas:
2018-04-11 Page 8 of 18
Figure 7: Panels Front view
By parametrization in the ETS the following button partitionings are available:
•Merged buttons
Here, the three sensor areas (A, B, C) are combined to form a one large panel. To carry
out the action programmed in the ETS, touch by hand the surface, behind which the
Enertex®-ProxyTouch is located.
•Single buttons
Here, each sensor area (A, B, C) represents a a control panel. To carry out the action
programmed in the ETS, touch by hand the point on the surface, behind which the
corresponding control panel is located. For all sensor areas a double click is possible.
The double click is triggered by two quick consecutive touches.
•Slide gestures
Here the slide gesture is assembled by the sensor areas (A→C) and (C→A). To carry
out the action programmed in the ETS, sweep with the open hand over the surface,
behind which the Enertex®-ProxyTouch is located. To detect a slide gesture the hand
movement must not be too slow. The sensor areas have two button functions, wherein
for all sensor areas a common single button and a double click is possible. The double
Enertex® Bayern GmbH – Ebermannstädter Straße 8 - 91301 Forchheim - Deutschland - mail@enert ex.de
click is triggered by 2 quick consecutive touches.
Lock object
In each button partitioning the object function Lock object is available. With this object it is
possible to lock the sensor areas whereby no action can be carried out any more. This is
important for example for the cleaning operation to prevent unwanted triggering. If the object has
been set, it can be heard by an audible signal (buzz) during operation of the sensor.
