The heating water flow must be
ensured using a dual differential
pressureless manifold (see
Chap. 8.4.3 on p. 178)
The use of the DDV 32 compact
manifold is recommended for
heat pumps with a heating water
flow rate up to max. 2.5 m

Operation of the circulating
pump (M16) in the generator
circuit with the compressor in
heating operation only, to avoid
unnecessary operation

A safety temperature monitor
which protects the distribution
system from impermissibly high
temperatures must be used
when the buffer tank connected
in series is charged externally.
The dual differential
pressureless manifold protects
the heat pump since the
circulating pump (M16) in the
generator circuit is only active
when the compressor is running
in heating operation.
The heating circuit pumps M13/
M15 supply the flow around the
return flow sensor and prevent
the heat pump from switching on
when the system temperatures
are too high.
