General system schema
System schema 0
Consists only of the module heat generator
(maximum of 4) and optionally an external
heat source and external heat request.
Without additional optional modules.
System schema 1
System consisting of a heat generator and
optionally an external heat source, external
heat request, buffer tank, heating circuits and
hot water tanks. The external heat request
requests the buffer tank. When the number of
heat generators of the system is 0, the heating
is carried out via an external heat generator.
System schema 2
Buffer must be present. Buffer with integrated
hot-water tank. Other modules optional. When
the number of heat generators of the system is
0, the heating is carried out via an external
heat generator. This scheme can also be used
for a buffer tank with fresh water module.
System schema 3
Without buffer. A hydraulic separator exists.
Other modules optional. When the number of
heat generators of the system is 0, the heating
is carried out via an external heat generator.
