1. INTRODUCTION
CSE2 MIX F W 1F twin-line pump station is designed for mixed heating circuits.
It provides ow through the heating system, mixes to the outlet temperature
using a motorized mixing valve (controlled by an external controller). 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.

PUMP SETTINGS
The circulation pump can be controlled by an external PWM signal (prole for use in heating
systems) or without a PWM signal by selecting a pump performance curve. The maximum
operating curve of the pump can be dened.
With PWM signal the pump speed changes with the signal value up to the
maximum of the selected curve.
Without PWM signal the pump runs at maximum speed according to the
selected curve.
When switched on, the pump runs at factory settings or the last setting. The display shows the
momentary pump performance that is shown by LEDs according to the table below.
DISPLAY STATE PERFORMANCE in % of P1max
1 ashing green LED standby mode
(external control only) 0
1 green + 1 yellow LED low performance 0–25
1 green + 2 yellow LEDs medium-low performance 25–50
1 green + 3 yellow LEDs medium-high performance 50–75
1 green + 4 yellow LEDs high performance 75–100
SETTINGS DISPLAY AND SETTINGS CHANGE
The selected setting is displayed by pressing the grey button on the pump display. The
individual performance curves are indicated by the light signal as shown below. WARNING:
LEDs may be turned by 180°, depending on the specic pump type.
If you need to set a different performance curve, follow these steps:
• Press and hold the grey pushbutton until the LEDs start ashing. The pump will switch to
adjustment selection mode.
• To select your desired setting, press the button repeatedly until you nd the setting you
need (see the gures below). If you pass the desired setting, you have to go one more
round until it appears again – there is no way back in the loop.
• Release the button for more than 10 s and the LEDs will return to “performance view“,
while the last setting is saved.

3.2. AVC ACTUATOR FOR MIXING VALVE
LK 840 mixing valve is controlled by an AVC actuator with three-point control. The current
position of the valve member can be read from the sight glass on the actuator housing. The
control mode switch is used to set automatic or manual control. If manual control is set, the
actuator is controlled by turning the control knob.

3.4. CHECK VALVE
The check valve downstream of the lter prevents natural circulation in the heating circuit.
Check Valve Pressure Drop Diagram
3.5. FILTER WITH MAGNET
The lter located on the return line of the pump station is designed to collect solid particles
from the working uid. It consists of a brass housing, a removable metal strainer collecting
coarse impurities and a brass cap with magnet that collects magnetic impurities.
The lter should be checked regularly and cleaned if necessary. The lter shall be cleaned
with the circulation pump switched off and the section where the lter is installed shut
off. In the section upstream of the lter, shutting off is done by a ball valve, in the section
downstream of the lter the piping 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.

3.6. BALL VALVES
Technical Data
Kv value 20,2 m3/h
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 not present on the valve during operation.
The valve is closed by turning the lever clockwise by 90°. The open / closed position on the
ball valve is indicated by a groove on the control wheel. The groove is perpendicular to the
direction of ow when the ball valve is closed. The ball valve opens by turning the lever anti-
clockwise by 90°, the groove is then in the ow direction. Before closing / opening the ball
valve, the top section of the insulation shall be removed rst. As a result, unintentional closure
of the system by an unauthorized person is not possible.
