Baseline Unit
The basic device consists of a ready-to-use heat pump for in-
door installation, complete with sheet metal casing, control
panel and integrated heat pump manager. The refrigeration cir-
cuit is "hermetically sealed" and contains the fluorinated refrig-
erant R134a included in the Kyoto protocol. Information on the
GWP value and CO
2
equivalent of the refrigerant can be found
in the chapter 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 control box. A sensor for the external tempera-
ture including mounting hardware as well as a strainer are sup-
plied with the heat pump. The supply for the load current and
the control voltage must be installed by the customer.
The control wire of the brine pump (to be provided by the cus-
tomer) is to be connected to the control box. When so doing, a
motor protecting device is to be installed, if required.
The customer must provide both the heat source system and
the brine circuit manifold.

Accessories
4.1 Connecting Flanges
The use of flat-sealing connecting flanges allows the unit, as an
option, to be connected by means of flanges.
4.2 Remote control
A remote control 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
º
In the case of heating controllers with a removable operating
element, this can also be used directly as a remote control.
4.3 Building management
technology
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
ATTENTION!
!!
If the heat pump or circulating pumps are controlled
externally, an flow rate switch is required to prevent the
compressor from being switched on when there is no volume
flow.
