5�1 General
The modular buffer store is a central component in the
system to be installed. The energy generated is stored in
the buffer store and removed on demand.
A variety of connection options, are shown for both the
generation and distribution of heat for heating and hot
water.
Special applications are to be agreed with the manufac-
turer. Depending on the design of the circuits, an adjust-
ment and review of the hydraulic schematic is necessary.
NOTE
: The following hydraulic connections are a sche-
matic representation of the components and are used as
an aid for planning. They do not include all the neces-
sary safety devices according to EN 12828, components
maintaining constant pressure and possible additional
shut-off devices for maintenance and service work.
