Basic device
The 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
lent of the refrigerant can be found in the chapter Device infor-
mation. The refrigerant is CFC-free, non-ozone depleting and
non-combustible.
All components required for the operation of the heat pump are
located in the switch box. An outside temperature sensor in-
cluding fixing accessories and a dirt trap are supplied with the
heat pump. The supply for the supply voltage and the control
voltage must be installed by the customer.
The circulating pumps included in the scope of supply must be
installed in accordance with the hydraulic diagrams (see Cap. 4
on page XX) or the development documents. The electrical
connection of the circulating pumps must be established in ac-
cordance with Cap. 7.5.3 on page 8.
The control wire of the primary pump (to be provided by the
customer) is to be connected to the control box. When so do-
ing, a motor protecting device is to be installed, if required.
The customer must provide hydraulic components for the well
water circuit.

Accessories
4.1 Remote control
A remote display adds convenience and is available as a special
accessory. Operation and menu navigation are identical to
equiva-
2
those of the heat pump manager. Connection takes place via an
interface (special accessories) with RJ 12 Western plug.
NOTE
In the case of heating controllers with a removable control
panel, this can 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
interface plug-in card. The supplementary installation instruc-
tions of the interface card must be consulted regarding the
exact connection and parameterisation of the interface.
The following network connections can be made on the heat
pump manager:
Modbus
EIB, KNX
Ethernet
CAUTION!
If the heat pump or circulating pumps are controlled
externally, a flow rate switch is required to prevent the
compressor from being switched on when there is no volume
flow.

Transport
A lift truck is suited for transporting the unit on a level surface.
Carrying straps may be used if the heat pump needs to be
trans-ported on an uneven surface or carried up or down stairs.
These straps can be passed directly underneath the pallet.
CAUTION!
The heat pump must not be tilted more than 45° (in any
direction).
