3.1. Wilo-Para 25/8 SC PUMP
Wilo Para 25/8 SC circulation pump is a wet-running circulation pump permitting to
set speed control to Δp-v, Δp-c or n=constant. The operating status and possible faults
of the pump are displayed by means of LEDs directly on the pump display. It is used
exclusively for the circulation of liquids in hot water heating systems. Operating the
pump in other systems or in systems lacking water, containing air bubbles or not
pressurized can lead to its rapid destruction.

TROUBLESHOOTING, RESTART, FACTORY SETTINGS
If air is present in the pump:
Activate the pump venting function by pressing and holding the
operating button for 3 sec. The upper and lower rows of LEDs will
ash in 1sec interval, see Fig.
Pump venting takes 10 minutes, after that the pump returns to
current mode. In order to cancel pump venting, press and hold the
operating button for 3 sec.
Operating button locking/unlocking
To lock the operating button, press it for 8 seconds.
The selected setting then starts ashing and cannot be changed.
To unlock, hold down the operating button again for 8 seconds
and the LEDs will stop ashing.
Manual restart
If the pump has been inactive for a long time or is blocked, activate
the manual restart by holding the operating button for 5 seconds.
The LEDs ash sequentially clockwise. The manual restart takes
max. 10 minutes before the pump returns to normal operation.
To cancel the manual restart, hold down the operating button for
5 seconds.
If the pump does not get unblocked, contact a qualied technician.
Factory settings
To return to the factory settings, press and hold the operating button for at least
4 seconds (all LEDs ash for 1 second) and turn off the pump by unplugging. When
switched on again, the pump will run at the factory settings.

PUMP CONTROL
Constant speed operating mode and pump performance curve III are preset as
factory settings for the PARA SC pump. After switching on, the pump runs at the
factory setting or at the last setting. The settings can
be changed using the operating button, see below.
Briey press the control button to:
select the pump operating mode: constant speed, Δp-v
or Δp-c and the pump performance curve (I,II,III).
Press and hold the operating button for the specied time to activate:
- Pump venting function - hold the control button for 3 seconds.
- Manual restart - hold the operating button for 5 seconds.
- Locking/unlocking the operating button - hold the button for 8 seconds.
- Factory setting - hold the control button for at least 4 seconds and switch off the
pump by disconnecting it from the mains.
SETTING THE PUMP SPEED CONTROL MANNER
Briey press the operating button for 1 second to select the pump speed control manner
and pump performance curve. LEDs show pump settings (operating mode Δp-v / Δp-c
/ n=const and the respective performance curve).

PUMP SPEED CONTROL
The following speed control can be selected:
Variable differential pressure ∆p-v
Constant differential pressure ∆p-c
Constant speed n=const.
Variable differential pressure (∆p-v)
This prole is suitable for use with two-
line radiator heating systems to reduce
the noise caused by the ow of liquid
through thermostatic valves. If the ow
in the pipe network decreases, the
pump reduces the head in half. This
saves electrical energy by adapting
the head to the pumping capacity
requirement and lower ow velocities.
Constant differential pressure (∆p-c)
This prole is suitable for use in
underoor heating or for piping of
bigger diameters. It is also suitable
for all applications without variable
characteristics (e.g. pumps for HW
storage tank heating) and for single-
line heating systems with radiators.
The pump maintains a constant set
delivery head regardless of pumping
capacity.

Constant speed (n=const.)
This prole is suitable for use in
constant resistance systems that
require constant pumping capacity. The
pump runs uncontrolled in three preset
constant speed stages.

The actuator is factory set to motorized control and ready for operation.
Should it be inevitable to remove it or replace, please follow the instructions
in the appendix.
230 V, 50 Hz
3.2. MIXING VALVE W. ACTUATOR
The LK 840 mixing valve is equipped with a 3-point control actuator. The current valve member
position is obvious from the position of the line in the sightglass of the control knob. The slide
switch on the actuator housing can be used to switch between motorized and manual control.
When the manual control is set, the actuator is controlled by turning the knob.
3.3. CHECK VALVE
The check valve downstream of the filter prevents natural circulation in the heating circuit.
3.4. FILTER WITH MAGNET
The filter located in the return line of the pump station is designed to collect particles from
heating water. It consists of a brass housing, removable stainless-steel strainer collecting
coarse dirt, and a brass lid with a magnet that attracts magnetic particles.
The filter needs to be checked regularly, and cleaned when needed. Turn off the circulation
pump, close the ball valve upstream of the filter. Water inlet downstream of the magnet is
closed by the check valve. Unscrew the filter lid, remove the stainless steel strainer and flush
thoroughly. Wipe the impurities on the magnet and re-assemble the filter by inserting the
strainer, screwing in and tightening the lid.
3.5. BALL VALVES
Ball valves are intended to isolate the pump station from the heating circuit. Then it is not
necessary to drain the heating circuit for servicing (incl. cleaning the filter). In order to have
a more solid hydraulic section of the pump station, they are fixed to the rear mounting plate.
The ball valves are controlled by a lever that is placed inside the pump station insulation. The
valve is closed or opened by turning the lever by 90°. The state of the valve is indicated by
the groove on the control hexagon of the valve. The ball valve can be accesses only after the
front section of the insulation is removed. As a result, unintentional closure of the system by
an unauthorized person is not possible.

5. PUMP STATION INSTALLATION
The pump station is designed to be mounted on a wall or a manifold with 125 mm connection
pitch. In the rear section of the insulation there are two mounting holes for fixing the metal
plate to the wall. Mounting holes pitch is 80 mm.
The package includes a mounting kit that is used to fix the pump station to the
intended place. The mounting kit includes:
Screw 5x50, round head 2 pcs

6. TEMPERATURE SENSOR INSTALLATION
The ball valve housings are equipped with a sheath for the temperature sensor, where the
sensor can be inserted and secured by a xing screw against being pulled out. In the top
and bottom section of the insulation there are passages to run the cables through, then it is
necessary to cut the appropriate part of the passage lock from the front part of the insulation
with a knife, so that the exiting cables are rmly wrapped around by the lock.
