The system components for the
heat source and an unmixed
heating circuit are integrated in a
heat pump in compact design.
Domestic hot water preparation
is optional.
If required, the 2 kW immersion
heater integrated into the com-
pact air-to-water heat pump can
be replaced by a pipe assembly.
Integration diagrams are clearly
marked through an 8-digit code
(e.g. 12211020).

The compact brine-to-water heat
pump can be directly connected
to the heating system due to the
integrated solid-borne noise in-
sulation.
The free compression of the in-
tegrated brine circulating pump
is set for a maximum heat ex-
changer depth of 80 m (DN 32).
For a greater heat exchanger
depth the free compression must
be checked and, if necessary, a
DN 40 pipe must be used.
NOTE
Heat pumps in compact de-
sign can not be used for biva-
lent systems.
