Basic device
The basic device consists of a heat pump for indoor installation
wired ready for use with metal casing, switch box and inte-
grated heat pump manager. The refrigeration circuit is "hermet-
ically sealed" and contains the fluorinated refrigerant R410A in-
cluded in the Kyoto protocol. Information on the GWP value
and CO
equivalent of the refrigerant can be found in the chap-
2
ter Device information. 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 XII) or the development documents. The electrical con-
nection 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 Connection flange
The device can optionally be switched to flange connection
using the flat-sealing connection flange.
4.2 Remote control
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
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.
4.3 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.
