Operation:
The PC-30-Vario filter control unit is
designed for timed on/off control of a 230V
AC filter pump or speed-controlled filter
pump (see wiring diagrams) according to a
user-programmable control program.
Backwashing can be performed using a 6-
way multiport valve and installed
EUROTRONIK-10 controller or using slide
valves and launched either manually or at
a specific time or pressure.
While the filter pump is running, the
swimming pool heater is controlled by the
electronic temperature controller. During
breaks in filter operation, the heater is
automatically switched off by the internal
interlock. The required water temperature
for the swimming pool can be set on the
front panel. The heater can also be
switched off from here. A floating contact
(terminals 26+27) and live contact
(terminal U2) are provided for the heater
connection.
The microprocessor automatically enables
the solar temperature controller when a
solar temperature sensor is connected
(part no. 3100000030). The free solar
energy is then used as the preferred
source for heating the swimming pool. The
auxiliary heating is switched on
automatically only when there is no energy
being supplied by the solar heating system.
If solar energy is available outside the filter
operating periods (timer off), the solar
heater will still start up along with the filter
pump. The solar temperature sensor is
suitable for use with direct flow solar
collectors in which the swimming pool
water flows directly through the absorbers.
This control unit is not intended for use
with other types of solar collectors. The

Operating instructions PC-30-Vario filter control unit Page: 4
absorber temperature must not exceed
80°C at the temperature sensor.
Connecting terminals are provided for an
NR-12-TRS-2 electronic water level control
unit (part no. 3030075020) for convenient
automatic control of the water level in the
swimming pool. This also protects the filter
pump from any damage which might arise
from running the filter installation without
water.
The INFO button on the front panel can be
used to change the user language and to
retrieve various operating parameters.
Spare terminals are available for
connecting additional devices such as
chemical dosing equipment. Terminals
24+25 are floating contacts for custom use.
The relay contact between terminals 24
and 25 is closed during the filter operating
times and open outside the filter operating
times. This contact is rated for a maximum
voltage of 230V and a maximum current of
3A.
The connecting terminals for the winding
protection switch are designed for
connecting a thermal winding protection
switch built into the filter-pump motor
winding. If this switch opens, e.g. as a
result of the motor winding getting too hot,
the filter pump is switched off automatically
along with the heater and dosing
equipment. Once the winding protection
switch closes after the motor winding has
cooled down, the units are automatically
switched back on. There is no need for a
manual reset. The connecting terminals for
the winding protection switch carry 230V.
Indicator lights in the front panel show
when the filterpump and heater are
running, allowing easy checking of the
status.
ECO mode can be started automatically on
closure of the swimming pool cover (limit-
switch terminals 28 + 29).
Installation
The swimming pool must be designed to
prevent consequential damage resulting
from a potential technical fault, power
failure or faulty controller.
Electrical connection
The control unit must be mounted such
that it is protected from moisture in
accordance with its degree of protection.
The power supply for the unit must be
provided via an all-pole disconnection
switch with minimum contact gap of 3mm
and via a residual-current circuit breaker
with a fault current IFN of 30mA. When
using variable-frequency drives and speed-
controlled pumps, the residual-current
circuit breakers stipulated for these devices
must be used and the relevant regulations
observed.
Always disconnect the unit from the
power supply before opening the case.
All electrical wiring and calibration and
servicing work must be performed
solely by an approved electrician. The
attached wiring diagrams and all
applicable safety regulations must be
observed.
The switching outputs of the PC-30-Vario
are not intended as a voltage supply for
variable frequency drives. Please refer to
the relevant wiring diagrams in these
operating instructions.
Low-voltage lines
Low-voltage lines must not be laid along
with three-phase or AC power cables in the
same cable conduit. In general, always
avoid routing low-voltage lines close to
three-phase or AC power cables.
Connecting the filter pump
Note that it is permitted to connect only
one pump. Connections must be made in
accordance with the following wiring
diagrams.

thermowell
Connect the swimming-pool temperature
sensor to terminals 30 and 31. The
temperature sensor is supplied as standard
with a cable length of 1.5m. If required, this
can be extended to a maximum length of 20m
using a twin-core cable (min. cross-section
0.5mm²). Avoid running the sensor lead close
to mains cables to prevent potential
interference. The sensors can be connected
either way round (polarity not important).
Since precise temperature control can only be
achieved with good heat transfer between the
temperature sensor and swimming pool water,
an R ½" thermowell (part no.
3200200003) must be fitted in the piping
system.
In addition, a solar temperature sensor (part
no. 3100000033) can be connected to
terminals 32 and 33 (option). The temperature
sensor is supplied as standard with a cable
length of 20m. If required, this can be
extended to a maximum length of 50m using a
twin-core cable (min. cross-section 0.5mm²).
Avoid running the sensor lead close to mains

Operating instructions PC-30-Vario filter control unit Page: 10
cables to prevent potential interference. The
solar temperature sensor should be fitted at
the solar collector output in good thermal
contact with the returning water flow. The
temperature at the installation position for the
temperature sensor must not exceed 80°C.
Frost protection
When the frost protection function is enabled,
the temperature sensor connected to terminals
32 and 33 is used as the air temperature
sensor for frost protection. Solar temperature
control is disabled when frost protection is in
use. In installations without solar heating, the
frost-protection sensor should be installed in a
suitable position outdoors. Once the
temperature at the temperature sensor drops
below 0°C (factory setting), the filter system is
activated. In this case, the temperature
controller regulates the heater to a target
temperature of 3°C.
Fuses
The electronic controller is protected by a 0.5A
microfuse located on the printed circuit board inside
the control unit. A separate 3.15A microfuse is
provided for each of the following devices: heater,
backwash valve, rinsing valve and solar actuator. The
customer must fit mains fuses of maximum rating 16A
to provide short-circuit protection for the filter pump.
ECO mode (energy saving mode)
In this operating mode, the filter pump runs at
minimum speed. ECO mode can only be used
during the programmed filter operating periods.
It is activated by the ECO timer (during the
filter operating period), by the operating-mode
selector switch or by the cover limit-switch
(with the cover closed the pump runs at ECO
speed during the filter operating period).

Service Terminal
An osf Service Terminal (part no. 3010000900) can be connected
to the control unit. This terminal can be used to set the optimum
control unit configuration for a particular swimming pool installation,
for commissioning the control unit and for fault diagnosis. The
connector for the Service Terminal is located on the printed circuit
board inside the control unit. Always disconnect the control unit
from the power supply before opening the case and plugging
in the Service Terminal. After switching on the control unit, the
display on the Service Terminal shows the first 4 lines of the
diagnostic text, e.g.:
Filtersystem off
Temp. reached
Water: 23.0°
Solar: 38.4°

outside the set filter operating times because the temperature
controller is operating in priority mode.
Pump disabled
The filter pump has been temporarily switched off by the
EUROTRONIK-10 controller or the NR-12-TRS-2 water level
controller.
