2 Purpose of the Heat
Pump

2.1 Application

The hydro tower constitutes the interface between a non-revers-
ible heat pump and the heat distribution in the building. The
hydro tower contains all hydraulic components required between
heat generation and heat distribution with an unmixed heating
circuit. A dual differential pressureless manifold with a buffer tank
allows an energy-optimised hydraulic integration of the heat gen-
erator and the heat distribution.
NOTE
The device is not suitable for operation with a frequency converter.

2.2 General properties

 Low installation effort
 All components easily accessible
 Ready-to-connect, contains all essential components, i.e.
pumps, shut-offs, safety devices and heat pump manager
 Integrated 300l hot water cylinder
 Integrated buffer tank reduces operating cycles of the heat
pump, thus increasing the efficiency of the system
 The infinitely adjustable operation of the circulating pump in
the heating circuit allows the output to be adjusted according
to need.
 Optional immersion heater up to 6 kW
 Switchable pipe heater (2 / 4 / 6 kW) for supplementary heat-
ing.

Scope of supply

3.1 Basic device

Hydraulic components
 Dual differential pressureless manifold
 Buffer tank, 100 litres
 Unmixed heating circuit including controlled circulating
pump (infinitely adjustable or 3 stages), shut-offs and back-
pressure features
 Primary circuit heat generation including circulating pump (3
stages), shut-offs

3.2 Switch box

ATTENTION!
Before opening the device, ensure that all circuits are powered down.
The switch box is located in the upper area of the hydro tower.
After removing the front cover, the switch box is freely accessi-
ble.
The switch box contains the supply connection terminals, heating
contactors, Bus connections (connecting line to the heat pump)
and the heat pump manager (HWK 332 Econ5S).

3.3 Heat pump manager

The integrated heat pump manager (HWK 332 Econ5S) is a con-
venient electronic regulation and control device. It controls and
monitors the entire heating system based on the external tem-
perature, as well as domestic hot water preparation and safety
systems.
The external temperature sensor (to be connected on site) in-
cluding the fixing accessories, is included in the scope of supply
of the heat pump manager.
The enclosed operating instructions describe the function and
use of the heat pump manager.
