Dachs Pro 20 ST
Description of hydraulic integration:
The heat transfer to the heating circuit is performed via a controlled pump. This buffer discharge system is controlled by
the MSR Pro 20 ST. For the detailed connection/transfer points of the flow and return lines in the heating circuit, please
refer to the hydraulic schematic diagrams.
The length of the connection of the on site flow and return lines (SE940 buffer vessel transfer) is 1 1/4".
The dimensioning of the on site flow and return lines from the buffer vessel to the heating circuit depend on the distance.
In most cases, 1” of tubing is sufficient. For longer distances, please consult the SenerTec planning hotline on dimensioning.
All required temperature sensors (sensors
F1-F7
including the external sensor
AF
) are included in the scope of delivery.
●
Sensors F1 - F4 (assembly at the sensor lugs of the SE940 buffer vessels).
●
Sensors F5, F6 and F7 (assembly using the provided tension strap according to the positioning on the
schematic diagrams).
Dachs Pro 20 ST scope of delivery for hydraulic integration:
●
Dachs inlet connection set
(screw connection to CHP, fittings, manual vents, heating water hose and ball valve).
●
Dachs outlet connection set
(screw connection to CHP, fittings, 3 bar safety valve, manual vents, heating water hose and ball valve).
●
Magnet filter (TF1 total filter, Fernox)
●
Pressure gauge.
●
Buffer discharge pump with shut-off set and red thermometer
(to be installed in the flow from the buffer vessel to the heating circuit).
●
Shut-off set with blue thermometer
(to be installed in the return from the heating circuit to the buffer vessel).
●
Automatic vents for buffer vessels.
●
Filling and discharge set for the SE940 buffer vessels.
Information on hydraulics in the system test phase:
For system testing, only one controller for filling and discharge of the buffer vessels will
be available. Control of a second heat generator or distribution as well as multi-module
functionality is
not
intended. During system tests, the Dachs Pro 20 ST is always operated with
2 SE940 buffer vessels.
The control system is only designed for hydraulic integration.
i
Attention:
All hydraulic (heating water side) lines are to be insulated
on site
.
●
Risk of burning
(potentially high temperatures).
●
Heat losses
(in case of non-insulated lines on the surface).
