1.2 Equipment description
WPF is a heating system which is designed for
operation as brine/water heat pump. The heat
pump extracts energy from the heat source
medium i.e. brine at a low temperature level.
This extracted energy is then transferred to
the heating water at a higher level, enriched
with the energy transferred by the compressor.
Subject to the heat source temperature, the
heating water can be heated up to a flow tem-
perature of 60 °C.
Inside the WPF, a heating circuit pump and
a three-way valve have been integrated for
diverting the flow either to the heating circuit
or the DHW circuit. DHW is heated by pumping
the heating water, which has been heated by
the heat pump, through a heat exchanger into
the DHW cylinder, where it transfers its energy
to the DHW.
The equipment is regulated by an integral,
weather-compensated return temperature
controller (heat pump manager WPMiw(triple
phase) and WPMi(single phase).
The WPMi/WPMiw also regulates the DHW
heating to the required temperature. DHW
heating will be completed automatically by an
integral electric booster heater, if either the
high pressure sensor or the hot gas limiter of

1.1 Equipment summary
the heat pump responds during DHW heating,
subject to the ECO function being enabled.
Subject to the ECO function being enabled, the
DHW heating will terminate and the set DHW
value overwritten with the actual DHW tempe-
rature that has been achieved.

Heat pumps operate with particular econo-
my and environmental responsibility when
they work with a maximum flow tempera-
ture of 35 °C. Low flow temperatures can
be achieved by using area heating systems
(e.g. underfloor heating or wall heating
systems).
z
Size radiators so that the maximum re-
quired flow temperature does not exceed
45 °C.
z
Activating the control parameter „Pump
cycling“ can reduce the power drawn by
the circulation pump. In this connection,
refer to your local heating contractor.
z
When activating the „WW ECO“ parameter,
the heat pump heats DHW exclusively on
its own, i.e. without the additional electric
booster heater. In that case, the DHW
temperature is automatically limited to that
value, which the heat pump can actually
achieve. If, for reasons of pasteurisation,
you want to heat to 60 °C at least once
every day, activate the „Pasteurisation“
parameter. In this connection, refer to your
local heating contractor.
