1. INTRODUCTION
CSE2 MIX-BP F W6 1F twin-line pump station is designed for mixed heating circuits. It
provides flow through the heating system, mixes to the outlet temperature. Since the mixing
valve is not fitted with an actuator, any actuator may be used that will meet the needs of the
particular system and control. The pump station includes a filter with magnet, so it is also
suitable for older steel pipe systems.
It can be easily mounted on a wall or on a manifold.

Description of Pump Frofiles
a) Proportional pressure
• This mode is suitable for use in heating systems with radiators to reduce noise caused
by liquid flow through thermostatic valves.
• Head (pressure) is reduced with sinking flow rate (growing system pressure drop).
• Pump operating point: moves up or down on the selected proportional pressure curve
depending on the current system pressure drop.
PROFILE DESCRIPTION

pressure
I The lowest curve of proportional pressure
II The middle curve of proportional pressure
III The highest curve of proportional pressure
AUTOADAPT
Automatically controls performance in the range
from the highest to the lowest proportional
pressure curve
b) Constant pressure
• This mode is suitable for use with underoor heating or larger pipe sizes. It is also
suitable for all applications without variable characteristic (e.g. pumps for hot water
storage tanks or for a circuit with a heat exchanger).
• Head (pressure) is kept constant in the whole ow rate range (does not change with
the system pressure drop).
• Pump operating point: moves on the selected constant pressure curve depending on
the current system pressure drop.

c) Constant speed
• This mode is suitable for utilising the maximum pump output or for use in systems
with constant resistance that require constant pumping capacity.
• Head (pressure) is growing with sinking ow rate (growing system pressure drop).
• Pump operating point: moves on the selected constant pressure curve depending on
the current system pressure drop.

3.2. MIXING VALVE
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 should be checked regularly and cleaned if necessary. Switch off the circulation
pump, close the ball valve upstream of the filter. The water inlet downstream of of the filter is
shut off by a check valve. The filter 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.

3.5. 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 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.

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
6.4 stainless steel washer, DIN 9021/A2 2 pcs
Wall plug 8mm TX 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 fixing 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 firmly wrapped around by the lock.
