Operating instructions for Pool control-40 filter control unit
Page: 5 (24)
Function
The
PC-40 control unit lets you time the on/off cycles of a filter pump based on a user-programmable
daily or weekly schedule. A 400V 3-phase pump, a 230V single-phase AC pump or a variable-speed filter
pump may be used as the filter pump (see wiring diagrams). When using a 3-phase filter pump, a 3-phase
electronic motor protection device protects the pump from overload (current range has continuous adjustment
up to 8A).
Backwashing can be performed using a 6-way multiport valve and installed EUROTRONIK-10 controller or
using slide valves under manual, timed or pressure-dependent control.
The built-in level control is designed for use with overflow pools with spillway (balancing tank) and for skimmer
pools.
While the filter pump is running, the swimming pool heating is controlled by the electronic temperature
controller. During pauses in filtration, the heating is automatically switched off by the internal interlock. The
required water temperature for the swimming pool can be set on the front panel. The heating can also be
switched off from here. A live contact (terminal U2) and volt-free floating contacts (terminals 17&18) are
available for connecting the heating system. Terminals are provided for connecting an
solar actuator
when operating solar absorbers that carry a direct flow of water from the pool. This control unit is not intended
for use with other types of solar collectors. The absorber temperature must not exceed 80°C at the
temperature sensor.
Terminals for connecting level sensors can be used for convenient automatic control of the water level in the
swimming pool. There are also terminals for connecting a flow sensor or a pressure switch, and a winding
thermostat contact. These provide extra protection for the filter pump against potential damage from dryrunning of the filter installation.
Spare terminals are available for connecting additional devices such as underwater lights and chemical dosing
equipment. A load (230V/max. 3A) connected to terminal U4 (auxiliary output) can be timed to switch on and
off by its own dedicated timer in the unit. Terminal U3 (dosing equipment) carries 230 V only while filtration is
running, but is de-energized outside filtration times. Terminals 15&16 (dosing equipment) are volt-free floating
contacts for custom use. The relay contact between terminals 15 and 16 is closed while filtration is running,
and open outside filtration times. This contact is rated for a maximum voltage of 230V and a maximum power
of 400W (cos ϕ=0.6).
Terminals 19&20 are volt-free floating contacts that can be used for fault indication.
The connecting terminals for the winding protection switch (WSK terminals) can be used to connect a winding
thermostat built into the filter-pump motor winding. If this thermal switch opens, e.g. as a result of the motor
winding getting too hot, the filter pump is switched off automatically along with the heating and dosing
equipment. Once the winding protection switch closes again after the motor winding has cooled down, the
units automatically switch back on. There is no need for a manual reset. The connecting terminals for the
winding protection switch carry 230V.
The motor protection device can only be used with 400V/50Hz filter pumps connected to terminals U1/V1/W1.
Motor protection is not active if you have selected a configuration using a variable speed pump or a 230V
pump.
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

Operating instructions for Pool control-40 filter control unit
Page: 10 (24)
Connecting a main drain valve (ECO valve)
A main drain valve (ECO valve) or a valve for water extraction from the pool walls can be
connected to terminals U7 and U8. Connect a 2-way valve to terminal U7 and neutral
terminal N. For a 3-way valve, use terminal U7 for "OPEN" and terminal U8 for "CLOSE".
This contact is rated for a maximum load of 230V/1A.
For overflow pools with spillway, this valve is opened in ECO mode to minimize evaporation
losses.
If this valve is also meant to be opened during backwashing, then the option Backwashing floor drain: valve open in BW must be selected in the configuration menu.
Connecting a fault indicator
An external fault indicator can be connected to volt-free floating terminals 19 and 20. This
contact is rated for a maximum load of 230V/4A.
Connecting a flow sensor
A flow sensor or a pressure sensor can be connected between terminals 21 and 22 instead
of the factory-fitted link, in order to provide additional protection for the pump against dryrunning. During filtration, a certain maximum time (factory set to 10 seconds, adjustment
range 5-60 sec) is allowed after the filter pump starts running before this contact must close.
If the contacts do not close in this time, the filter pump is switched off and the fault indicator
light comes on. This contact is not polled during backwashing.
The terminals carry a safety extra low voltage.
Connecting a pressure switch
A pressure switch fitted in the pressure line or in the gauge port of the central valve can be
connected to terminals 23 and 24. The backwash process starts if the floating contact of the
pressure switch is closed for at least 10 seconds.
The terminals carry a safety extra low voltage.
Operating instructions for Pool control-40 filter control unit
Page: 11 (24)
Connecting a cover limit-switch
A limit switch for the swimming-pool cover can be connected to terminals 25 and 26. This
switch automatically starts ECO mode when the cover is closed.
The terminals carry a safety extra low voltage.
Level control
The built-in level control is designed both for overflow pools with spillway and for skimmer pools. The version
to be used must be specified when configuring the control unit before use: in the configuration menu select
either the option Level control - type: collect. vessel or Level control - type: skimmer pool.
Overflow pools with spillway
electrode probes must be used as the level sensors.
Thanks to the strain relief provided for the cable, these probes can be
suspended by this dedicated cable in the overflow balancing tank. It
does not matter if the individual probes touch each other. The probes are
fixed above the tank using the
probe holder.
The dedicated cables must be taken to a junction box installed by the
customer. A cable must be laid from this junction box to the control unit
2
(e.g. cable NYM-0 5x1.5 mm ). The cable must not exceed 30m in
length. The cable must not be laid alongside mains power cables.
The probes operate with safety extra low voltage (SELV).
Take special care when fitting the probes to ensure they are connected
in the correct order, because the installation will not work if the probes
are mixed up.
Use with outdoor pools
Depending on the design of the pool installation, rain water in an outdoor pool can raise the water level,
triggering the "automatic actuation" function. If you don't want this to happen, you can disconnect the
"automatic actuation ON" probe (terminal 39). All the other probes are needed for the control function to work,
so must not be omitted or bypassed.

on
the
individual
circumstances, but must be
no less than 5 cm to ensure
sufficient switching intervals.
Dry-running protection: pump OFF
earth
How level control works for balancing tanks
Level control for balancing tanks performs the following functions:
a. Controlling the water level.
When water is lost from the swimming pool, e.g. through evaporation or backwashing, causing the
water level to drop to below the "OPEN solenoid valve" probe (terminal 37), the solenoid valve
(terminal U9) opens and the inflowing fresh water causes the water level to rise. As soon as the rising
water level reaches the position of the "CLOSE solenoid valve" probe (terminal 38) and touches this
probe, the solenoid valve closes the supply of fresh water.
b. Protecting the filter pump against dry-running.
When water is lost from the swimming pool, e.g. from backwashing, causing the water level to drop to
below the "Dry-running protection / pump OFF" probe (terminal 36), the level control system switches
off the filter pump to prevent it being damaged by running without water. As soon as the water level
has returned to the height of the "Dry-running protection / pump ON" probe (terminal 37) and touches
this probe, the level control system automatically switches the filter control unit back on.
c. Automatic actuation.
If water displacement in the swimming pool has increased the water level in the balancing tank so that
it touches the "automatic actuation ON" probe (terminal 39), the level control system automatically
switches on the filter pump. The water is then pumped back into the pool, avoiding unnecessary loss
of precious water. The "automatic actuation ON" probe must be placed a few cm lower than the
overspill.
Pools with skimmer
POOLcontrol -40

float switch
An
mini float switch must be used as the sensor for skimmer pools.
The float switch lead can be extended with a cable (2x0.75mm²) of up to
30m in length. Please note that the connection must be absolutely
watertight. The float-switch connecting cable must not be laid alongside
other current-carrying cables.
The mini float switch operates with safety extra low voltage (SELV).
In this operating mode a time delay is automatically enabled in
conjunction with the mini float switch. This adjustable time delay
prevents over-frequent switching as a result of waves moving the pool
water. The delay length can be adjusted in the configuration menu.

skimmer wall
Fit the mini float switch on the sliding bracket. Then fasten the fixing rail
vertically on the skimmer wall at the approximate height required for the
water level. You can then set the water level by moving the sliding
bracket up and down the rail. Tighten the screw to fasten the sliding
bracket in place. All the parts fit easily inside each other so no great force
is needed.

Use without level control
If you do not want to use the built-in level control, you must select the option Level control - type: skimmer pool
in the configuration menu.
Solenoid valve for topping up the water level
A normally closed solenoid valve must be used for the water intake. This valve must be
connected to terminals U9 / N of the control unit. A suitable solenoid valve (R½"), part
number 1090005804, is available from the
range.
Temperature sensors
Pool temperature sensor
Connect the swimming-pool temperature sensor to terminals 29 and 30. 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.
-thermowell
Since precise temperature control can only be achieved with good heat transfer
between the temperature sensor and swimming pool water, an
R1/2"
thermowell (part no. 320.020.0003) must be fitted in the piping system.
The sensors can be
connected either way
round (polarity not
important).

Page: 14 (24)
Solar temperature sensor
In addition, a solar temperature sensor (part no. 3100000033) can be connected to terminals 31 and 32. 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 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.
Air temperature sensor
In addition, an air temperature sensor can be connected to terminals 33 and 34. This sensor is used for
controlling the automatic frost protection function.
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 outputs: heating, dosing equipment
and auxiliary output. The customer must fit mains fuses of maximum
rating 16A to provide short-circuit protection for the filter pump.
