1. INTRODUCTION
CSE2 MIX-BP F W8 1F twin-line pump station is designed for mixed heating circuits.
It provides ow through the heating system, mixes to the outlet temperature by a
manually controlled mixing valve (any actuator may be used that will meet the needs
of the particular system and control). The pump station includes a lter with magnet,
so it is also suitable for older steel pipe systems. It can be easily mounted on a wall or
on a manifold for multiple heating circuits.

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 if needed, also 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.

3.4. FILTER WITH MAGNET
The lter should be checked regularly and cleaned if necessary. Switch off the circulation
pump, close the ball valve upstream of the lter. The water inlet downstream of of the lter is
shut off by a check valve. The lter cap needs to be unscrewed, the metal strainer removed
and rinsed thoroughly from any dirt. Dirt trapped on the magnet must be wiped off and then
reassembled by inserting the strainer, screwing in and tightening the cap.
3.2. MIXING VALVE
valve member

D-shaft
knob arrow
The knob arrow points always to the middle
of the valve member. In this direction, the
valve is closed.
3.3. CHECK VALVE
The check valve downstream of the lter prevents natural circulation in the heating circuit.

Regulus CSE2 MIX-BP F W8 1F - www.regulus.eu
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 lter). In order to have
a more solid hydraulic section of the pump station, they are xed to the rear mounting plate.
The ball valves are controlled by a lever that is placed inside the insulation. The valve is
closed / opened by turning the lever by 90°. The open / closed position on the ball valve is
indicated by a groove on the valve‘s control hexagon. For access to the ball valve, the top
section of the insulation shall be removed. As a result, unintentional closure of the system by
an unauthorized person is not possible.

pitch. In the rear section of the insulation there are two mounting holes for xing the metal
plate to the wall. Mounting holes pitch is 80 mm.
Installation dimensions are shown in the gure below.
The package includes a mounting kit that is used to x the pump station to the
intended place. The mounting kit includes:

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.
