2 Notes on the documentation
2.1 Original instructions for use
These instructions are the original instructions for use within
the context of the machine directive.
2.2 Observing other applicable documents
▶ You must observe all operating instructions enclosed with
the system components.
2.3 Storing documents
▶ Keep this manual and all other applicable documents
safe for future use.
2.4 Applicability of the instructions
These instructions apply for the following only:
Product types and article numbers
VPM 15 D basic module
0020133195
VPM 30 D expansion mod-
ule
0020133196
The 10-digit article number of the product is the seventh to
sixteenth number of the serial number (→ Page 12).
The article number can also be found on the identification
plate, which is fitted in the factory on the underside of the
product.
3 System
3.1 System characteristics
3.1.1 Basic principles of the system
The auroFLOW plus solar system acts as a heat generator
in a hot water heating installation with a buffer cylinder. In or-
der to cover the basic load and potential peak loads of the
heat demand, various heat generators are used in solar-sup-
ported heating installations, e.g. heat pumps, block heating
and generating plants and gas boilers. The hot water gener-
ation can be combined with the buffer cylinder.
The auroFLOW plus solar system comprises:
– Collector field
– auroFLOW plus solar charger
– Buffer cylinder
– Solar lines
– Heating water pipes
In addition, a system controller can be used to control all
components of the heating installation, e.g. the auroMATIC
VRS 620.
3.1.2 Design of coordinated system examples
1 Collector field with max-
imum six collectors (VFK
135 VD or VFK 140 VD)
2 auroFLOW plus basic
module
3 Buffer cylinder
A typical example for the use of the basic module of the
auroFLOW plus solar charger is solar-supported heating
in a single-occupancy house. Cylinder cascades and swim-
ming pool heating are possible.
1 Collector field with max-
imum 12 collectors (VFK
135 VD or VFK 140 VD)
2 Basic module and expan-
sion module auroFLOW
plus
3 Buffer cylinder
A typical example for the use of the basic module and ex-
pansion module of the auroFLOW plus solar charger is
solar-supported production of hot water in multiple-occu-
pancy houses. Cylinder cascades and swimming pool heat-
ing are possible.
For even larger applications, up to four solar chargers (basic
module and expansion module) can be cascaded. The col-
lector field can then be made up of up to 48 collectors.
