The heating water flow must be
ensured using a dual differential
pressureless manifold.
The heating circuit pumps (M13
or M15) supply the flow around
the return flow sensor and
prevent the heat pump from
switching on when the system
temperatures are too high.
In order to minimise the running
times, the circulating pump
(M16) in the generator circuit is
only operational when the
compressor is running.

Two heating circuits with a dual differential pressureless manifold and exter-

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.
With permanent charging
temperatures of over 50 °C, air-
to-water heat pumps must be
blocked via an additional
thermostat for domestic hot
water and swimming pool water
preparation (ID3).
The dual differential
pressureless manifold protects
the heat pump from excessively
high system temperatures, since
the circulating pump (M16) in the
generator circuit is only active
when the compressor is running
in heating operation.
Note: Domestic hot water and
swimming pool water cannot
be prepared via external
charging of the buffer tank
connected in series.
