230V filter control unit with solar control
Item No.: 310.000.0530
Function
The PC-30 filter control unit allows time-dependent switching on and off of a 30 V
alternating current filter pump in accordance with a freely-programmable switching
program.
heater of the swimming pool is controlled by the electronic temperature regulation system
while the filter pump is running. The heater is automatically switched off by the internal
interlock during filter pauses. The required swimming pool water temperature can be
selected on the front panel, or the heater can be switched off. A floating contact (terminals
+ 3) and a 30 V output (terminals U and N) are available for connecting the
heating. Terminals for a solar actuating drive are available for operation with solar
absorbers through which the swimming pool water flows directly.
The integrated frost protection function makes the swimming pool winter break easier to
deal with.
Terminals for electronic level regulation NR-1 -TRS- (Art. No. 30300750 0) enable
convenient automatic regulation of the swimming pool water level. The filter pump is also
additionally protected against damage which could be caused by filter unit operation
without water.
Bar valves for backflushing and rinsing can be connected directly to the PC-30 so that
separate backflushing control units are not necessary. If a 6-way valve is to be used for
backflushing, additional terminals for an EUROTRONIK-10 enable extension of the
filter control unit to an automatic filter and backflushing control unit for 6-way valves.
Extra terminals enable the connection of additional devices such as a dosing system.
Terminals 0 + 1 are floating, and can therefore be used individually. The relay contact
between terminals 0 and 1 remains closed during the filter periods, the relay contact is
opened outside these periods. This contact can be loaded with a voltage of maximum 30
V and a current of maximum 4 A.
Operation of filter pump and heater is displayed by indicator lamps in the front panel,
which means that checks can be made at any time.

The bridge fitted in the works between terminals 13 and 14 must be removed if level
regulation system NR-1 -TRS- is connected. The bridge can remain between these
terminals if no level regulation system is connected. Terminals 11 and 12 remain unused
in this case. These terminals carry mains voltage!
The bridge fitted in the works between terminals 3 and 5 must be removed if a
EUROTRONIK-10 system is connected. The bridge can remain between these terminals
if no EUROTRONIK-10 system is connected. Terminals 2 and 4 remain unused in this
case. These terminals carry mains voltage!
Opening any of the contacts between terminals 13 and 14 or 3 and 5 causes filter pump,
dosing systems and heater to be turned off immediately.
Closing any of the contacts between terminals and 4 or 11 and 1 causes forced
switching on of the filter pump, whereas heater and dosing systems are switched off.

- Submerged
sleeve
The swimming pool temperature sensor is connected to terminals 30 and 31. The
temperature sensor is supplied with a cable length of 1.5 m as standard. If required, this
can be lengthened to maximum 0 m (cross-section minimum 0.5 mm²) with a -core
cable. You should avoid routing the sensor cable near power cables to prevent possible
interference.
Since precise temperature control can only be achieved with good heat transfer between
temperature sensor and swimming pool water, an immersed sleeve R ½" (Art. No.
3 00 00003) should be built into the piping system. The sensor polarity is as required.
A solar temperature sensor (Art. No. 3100000030) can additionally be connected to
terminals 3 and 33 (optional). The temperature sensor is supplied with a cable length of
0 m as standard. If required, this can be lengthened to maximum 50 m (cross-section
minimum 0.5mm²) with a -core cable. You should avoid routing the sensor cable near
power cables to prevent possible interference. The solar temperature sensor should be
connected at the solar collector output and must have good heat contact to the returning
water flow. The temperature at the temperature sensor installation site may not exceed 80
°C.
Frost protection
If the frost protection function has been switched on, a temperature sensor connected to
terminals 3 and 33 serves as the air temperature sensor for frost protection. The solar
temperature regulation is switched off during frost protection operation. If the swimming
bath does not have solar heating, this sensor is also installed in a suitable location
outside. As soon as the temperature at the temperature sensor falls below 0 °C, the filter
unit is activated. The temperature regulation system then controls the heater with a set
temperature of 3°C.

Balancing the temperature controller
The electronic temperature regulator and the temperature
centre are balanced with one another in the works. If one of
the sensors is replaced, or if a sensor cable is extended, a
new balance must be carried out if necessary using the
potentiometers in the controller. Turning the water
temperature sensor potentiometer clockwise causes an
increase in the water temperature displayed. If the solar
sensor potentiometer is turned clockwise, a higher collector
temperature is displayed. Since the solar temperature

PC-30 Filter control unit operating manual Page: 10
regulation only works correctly with precisely balanced
sensors, this balance should only be carried out by a trained
service technician.
Fuses
The electronic control system is protected by a 0. 5A fine-wire
fuse on the PCB in the inside of the device. The short-circuit
protection for the filter pump must be provided by a backup
fuse of maximum 16A on site.
Service terminal
An osf service terminal (Art. No. 3010000900) can be
connected to this control system for optimum control system
settings for a wide range of swimming pool equipment and for
assisting in initial startup and fault diagnosis. The socket for
this is located on the PCB inside the device. Before opening
the housing and plugging in the service terminal, you
must ensure that the control system has been isolated
from the mains! Once the control system has been switched
on, the service terminal display shows the first 4 lines of the
diagnosis text, e.g.:

Water temperature
The current water temperature is displayed in this line. If the display does not
agree with the actual temperature, it can be readjusted using the adjuster on the
printed circuit board (see temperature regulation section). Turn the adjuster in a
clockwise direction to increase the displayed value. "Sensor break" will be
displayed if the temperature sensor is defective. Caution If both temperature
sensors are at the same temperature, the solar sensor must never display a
higher value than the water temperature sensor otherwise the solar heater
will not switch off.
