System schemes
It is possible to choose between different hydraulic
schemata, which reflect a certain structure of the system
with a different configuration of the function units (system
modules). The respective function volume is set by the
appropriate options (e.g. reflux lift, unmixed heating circuit,
...).
Solar systems are not shown, but it can be selected, which heating target is associated with it (buffer
tank, hot water tank, generic heating target such as swimming pool).
External heat sources are optionally available and are hydraulically similar to the connected heat
generator. They have an autonomous (external) controlled circulation pump.
The selection of a schema takes place by confirming the line System scheme and entering the number
of the desired schema.
