Scope of supply
3.1 Basic device with switch box
The heat pump contains the components listed below.
The basic device consists of a heat pump for indoor installation
wired ready for use with metal casing, switch box and integrated
heat pump manager. The refrigeration circuit is "hermetically
sealed" and contains the fluorinated refrigerant R410A included
in the Kyoto protocol. Information on the GWP value and CO
equivalent of the refrigerant can be found in the chapter Device
information. The refrigerant is CFC-free, non-ozone depleting
and non-combustible.

Dirt trap
Power contactors, a soft starter unit and the extended controller
unit are located in the switch box. It monitors and controls all heat
pump signals and communicates with the heat pump manager.
Communication and control or mains cables, which are to be
routed apart from each other, are fed through the cable gland
area on the baseplate. The connecting terminals can be ac-
cessed directly by removing the side cover.

3.2 Heat pump manager
The hydro-tower with heat pump manager included in the scope
of supply must be used to operate the (reversible) air-to-water
heat pump.
The hydro tower constitutes the interface between a 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 differen-
tial pressureless manifold with a buffer tank allows an energy-op-
timised hydraulic integration of the heat generator and the heat
2
distribution.
The integrated heat pump manager is a convenient electronic
regulating and control device. It controls and monitors the entire
heating system based on the outdoor temperature or room tem-
perature, as well as domestic hot water preparation and safety
systems.
The sensor for outside temperature to be mounted on-site incl.
fixing materials is included with the heat pump and hydro-tower
unit.

The functions and usage of the hydro-tower are described in the
operating instructions supplied.

Accessories
4.1 Remote control
5
A remote display adds convenience and is available as a special
accessory. Operation and menu navigation are identical to those
of the heat pump manager. Connection takes place via an inter-
face (special accessories) with RJ 12 Western plug.

NOTE
In the case of heating controllers with a removable control panel, this can
7
also be used directly as a remote display.
4.2 Building management system
The heat pump manager can be connected to a building man-
agement system network via supplementation of the relevant in-
terface plug-in card. The supplementary installation instructions
of the interface card must be consulted regarding the exact con-
nection and parameterisation of the interface.
The following network connections can be made on the heat
pump manager:
Modbus
EIB, KNX
Ethernet.
