Installation
With the EUROMATIK.net you have purchased a high-class swimming pool controller. It is an accurate
and sensitive system that needs to be treated gently at all times. The membrane at the front should not
come into contact with chemicals. The controller is cleaned with a soft cloth and some water, if required.
At the time of installation, the regulations and provisions applicable at the place of installation must be
complied with.
Mounting
The housing is fixed vertically and permanently to a solid wall with adequate load-bearing capacity. The
place of installation must be dust-free and protected against water in order to ensure that the device works
properly. The ambient temperature should lie between 0° C and + 40° C and should be as constant as
possible. The relative humidity must not exceed 95% and no condensation may occur. Direct incidence of
heat or sunlight on the device must be avoided. The control unit and the external touch panel are not
suitable for outdoor installation.
Installation when using a swimming pool cover
The display of the EUROMATIK.net contains, among others, switches for operating the swimming pool
cover. These switches are inactive or off at the time of delivery. The switches can be activated or enabled
while the controller is being commissioned by selecting a swimming pool cover in the relevant menu. The
EUROMATIK.net with the switches for the swimming pool cover enabled should be installed only at
a place from where it is possible to have an unrestricted view of the entire swimming pool. The
switches meant for the "Swimming pool cover" should not be activated at locations from which
unrestricted view of the entire pool is not available! The emergency stop switch must be installed
on-site.
Electrical Connection
The control device must be fixed at a location where it is protected against moisture in accordance with its
class of protection. The power supply to the device must be fed via an all-pin main switch with contact
opening width of at least 3 mm and a residual current circuit breaker (RCCB) with IFN30 mA. When using
frequency inverters and pumps having speed control, the residual current circuit breakers specified for this
must be used and appropriate regulations must be observed and followed. Before opening the housing, it
is absolutely necessary to de-energize the device electrically. The electrical connection as well as
the work of adjustment and servicing should be carried out only by an approved electrician! The

equipment and heater to be shut down immediately.
Closing the contact between the terminals 3and 4switches the filtration system on.
Additional input signals
Flow monitor
Instead of the jumper connected across the terminals 25 and 26 at the
factory, a flow rate monitor or a pressure monitor can be connected in order
to protect the pump additionally against dry running. Its contact must be
closed at the latest 10 seconds after the filter pump has started up, otherwise
the filter pump gets switched off and the fault indication lamp lights up. This
contact is not sensed in the backwashing mode of operation.
Pressure switch
A pressure switch that is installed in the pressure gauge connection of the
central valve can be connected to the terminals 27 and 28. The back-
flushing operation commences if the potential-free contact of the pressure
switch is closed for at least 10 seconds.
End position switch for the cover
A potential-free end position switch can be connected to the terminals 29 and 30, with which the system
switches to ECO mode automatically when the cover is closed.
External touch-screen operating panel
An external touch-screen operating panel (Item no. 212.070.0520) can be connected

0.8, item no. 102.000.1012) with a maximum length of 50 m is used for this
connection.
Laying the connecting cable near power cables must be avoided in order to rule
out the possibility of interferences.

Installation and Operation Manual of the EUROMATIK.net Page 13 (40)
-Bus system
An “Color Control" and an “Attraction Control" can be connected to the terminals 61 and 62. A 2-
core cable, 2 x 0.5 mm² with a maximum length of 50 m is used for connection to the EUROMATIK.
An WATERFRIEND MRD-1, MRD-2, or MRD-3 can be also connected to the terminals 61 and 62. A 2-
core cable, 2 x 0.5 mm² with a maximum length of 50 m is used for this connection, too.
RGB colour light
With the help of the additional "Colour
Control.net" (Item no.: 330.083.0000) the
EUROMATIK.net can also control the RGB
floodlight using the DMX bus. The controller of
the colour light is operated off the external
touch operating panel of the EUROMATIK.net,
which is mandatory in this case. The RGB
colour light cannot be controlled on the
internal display of the EUROMATIK.net.
Additional attractions
With the help of the additional "Attraction
Control.net" (Item no.: 310.610.0000) up to 6
additional attractions can be controlled, using the external touch operating panel of the EUROMATIK.net,
which is mandatory in this case. The attractions cannot be controlled on the internal display of the
EUROMATIK.net.
WATERFRIEND dosing system
The measurement, control and dosing systems WATERFRIEND MRD-1, MRD-2, MRD-3 can be
connected with the help of the bus system to the EUROMATIK.net. The dosing system can optionally
be operated off the external operating panel of EUROMATIK.net. The WATERFRIEND cannot be controlled
on the internal display of the EUROMATIK.net.
Level control
The integrated level control is suitable for swimming pools with an overflow gutter as well as those with a
skimmer basin. The variant that is being used must be specified at the time of commissioning the controller.
Swimming pools with overflow gutter
Immersion electrodes must be used as sensors. The tensile strength of the cable is adequate to
suspend the electrodes with the help of this special cable in the overflow
collection container, whereby the individual electrodes may touch one
another completely. The electrodes are fastened above the container
with the help of the electrode holder. The special cables are routed
together in a junction box to be installed on-site. One cable (e.g. NYM-0
5 x 1.5 mm2) is laid from this junction box up to the control device. The
cable length should not exceed 50 m.
When connecting the immersion electrodes, special attention must be
paid to ensure that the sequence is not interchanged, since doing so
inevitably lead to malfunctions of the system.
Use for outdoor pools
Depending on the design of the swimming pool facility, it may happen in
open-air pools that rainwater raises the water level and then activates
the "Overflow protection (Forced run)" feature. If this response is not
desirable, the electrode "Overflow protection" (Terminal 47) can be disconnected from the terminal. All other
immersion electrodes are necessary for the controller to work and cannot be omitted, or should not be
bypassed. Other options for the settings are given under: "Configuring the level controller".

Installation and Operation Manual of the EUROMATIK.net Page 14 (40)
Functional information for the level controller for the collection tank
The level controller for the collection tank has the following functions:
a) Controlling the water level.
If, as a result of loss of water in the swimming pool, for example, by evaporation or back-flushing,
the water level drops to below the immersion electrode "Solenoid valve OPEN" (Terminal 45), the
solenoid valve (Terminal U9) opens and the fresh water flowing in leads to the water level being
raised. As soon as the rising water level reaches the position of the immersion electrode "Solenoid
valve CLOSED" (Terminal 46) and touches the appropriate electrode, the solenoid valve closed the
supply of fresh water.
b) Dry running protection of the filter pump.
If the loss of water in the collection tank, for example, by back-flushing, drops the water level down
to below the immersion electrode "Dry run protection, pump OFF" (Terminal 44), the level
controller switches the filter pump off so that it does not get damaged as a result of water
shortage. As soon as the water level once again rises to the height of the electrode "Dry run
protection, pump ON" (Terminal 45) and touches the said electrode, the level controller switches
the filter controller on automatically.
c) Overflow protection (forced run operation).
If as a result of water penetration in the swimming pool the water level in the collection tank rises
and touches the immersion electrode "Overflow protection ON" (Terminal 47), the level controller
switches the filter pump on automatically. Now, the water is pumped back into the swimming pool
and thus, unnecessary loss of precious water is avoided. The immersion electrode "Overflow
protection ON" should be placed a few cm below the overflow level.
Other options for the settings are given under: "Configuring the level controller".
Swimming pools with skimmer
A mini float switch must be used as the sensor. The cable of the float switch
can be extended to a maximum length of 50 m with a cable provided on-site (2 x
0.75 mm²). Please note that the connection must be made so that it is water-
tight. The connecting cable of the float switch should not be laid along with other
power lines.
In this operating mode, time monitoring is automatically active in conjunction
with the mini float switch. This adjustable minimum time interval prevents
frequent switching operations as a consequence of wave movements in the
swimming pool water. Other options for the settings are given under:
"Configuring the level controller".
In normal mode of
operation, the water level
oscillates between the
electrodes "Solenoid valve
CLOSED" and "Solenoid
valve OPEN"
The difference in height
depends on the specific
conditions in the pool. In
order to achieve adequate
time gaps between the
switching operations, a
minimum of 5 cm must be
ensured.

The mini float switch is installed on the sliding bracket. Next, the
fixing rail is fastened on the skimmer wall vertically at about the
height of the desired water level.
You can choose the water level by pushing the sliding bracket in
the rail. The sliding bracket is fixed by turning the clamping screw.
All parts fit into one another easily so that it is not necessary to
use any force.
Solenoid valve for replenishing water
A normally closed solenoid valve must be used for the water supply. This is connected to the U9 terminal of
the controller. A solenoid valve (R½") with damped closure can be purchased under the item no.
109.000.5804 from the product range.
Temperature sensors
Swimming pool temperature sensor
The temperature sensor for the swimming pool is connected to the terminals
51 and 52. The temperature sensor is supplied with a default cable length of
1.5 m. If needed, this can be extended with the help of 2-core wire (minimum
cross-section 0.5 mm²) up to a maximum length of 20 m. The polarity of the
sensor is irrelevant. Laying the sensor cable near power cables must be
avoided in order to rule out the possibility of interferences.
Since accurate temperature control takes place only with proper heat transfer
between the temperature sensor and the water in the swimming pool, an
immersion casing R 1/2 " (Item no. 320.020.0003) should be installed in the
pipe system.
Solar temperature sensor
A solar temperature sensor (Item no. 3100000033) can also be connected to the terminals 53 and 54. The
temperature sensor is supplied with a default cable length of 20m. If needed, this can be extended with the
help of 2-core wire (minimum cross-section 0.5 mm²) up to a maximum length of 50m. The polarity of the
sensor is irrelevant. Laying the sensor cable near power cables must be avoided in order to rule out
the possibility of interferences. The solar temperature sensor must be fixed at the output of the solar
absorber and must have good thermal contact to the water flowing back. The temperature at the place of
installation of the temperature sensor must not exceed 80°C.

Atmospheric temperature sensor
An atmospheric temperature sensor can continue to be connected to the terminals 55 and 56. This sensor is
used to control the automatic frost protection feature. Moreover, this sensor can be used when operating a
swimming pool air heat pump to shut the heat pump down if the air temperature is too low. Either a water
temperature sensor (Item. no. 310.000.0001 (1,5m) or 310.000.0005 (5m), rsp.) or a solar sensor (item no.
310.000.0033) can be used for this purpose.
Connecting to the computer network
Connection to the Internet is carried out by the communication server. The WATERFRIEND MRD-3 is
connected using a standard Ethernet patch cable into the network wall outlet, the powerline adapter, the
wireless LAN access point or other suitable facilities.
After the EUROMATIK was connected to an active network outlet, the power supply can be turned on. The
web server in EUROMATIK now searches autonomously for the communication server and logs on to the
database.
If the "OSF" icon in the monitor is visible (see chart), the EUROMATIK has logged on to the
communication server.
