Integration of the heat pump in the heating system 8.4.3.2

8.4.3.2 DDV 50 dual differential pressureless manifold
Just like the dual differential pressureless manifolds DDV 25 and
DDV 32, the DDV 50 acts as an interface between the heat
pump, buffer tank and heating distribution system. Designed for
a maximum volume flow of 8.0 m³/h, the DDV 50 is particularly
suited to large system technology. The DDV 50 can be combined
with two distribution modules, the WWM 50 for an unmixed heat-
ing circuit and the MMH 50 for a mixed heating circuit.
Unmixed heating circuit module WWM 50
Pre-assembled module (nominal width DN 50) with insulation
shells for connecting an unmixed heating circuit, domestic hot
water preparation or swimming pool preparation. Can be used up
to a maximum heating water flow rate of 8.0 m³/h. The module of-
fers space for a circulating pump with a pump dimension of 280
mm (with flange and compensation piece) with a nominal width
DN 32 and a spacing of 180 mm.

Mixed heating circuit module MMH50
Pre-assembled module (nominal width DN 50) with insulation
shells for connecting a mixed heating circuit. A three-way mixer
with actuator (connection voltage 230 Volt) also comes pre-in-
stalled in the factory. Can be used up to a maximum heating
water flow rate of 8.0 m³/h. The module offers space for a circu-
lating pump with a pump dimension of 280 mm (with flange and
compensation piece) with a nominal width DN 32 and a spacing
of 180 mm.
