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 on the control panel. An external temperature sensor
including fixing accessories and a dirt trap are supplied with the
heat pump. The supply for the load current and the control volt-
age must be installed by the customer.
The supply lead of the brine circulating pump (to be provided
by the customer) must be connected to the control panel. If re-
quired, a motor protection device and/or contactor must be
provided here.
The customer must provide both the heat source system and
the brine circuit manifold.

Accessories

4.1 Brine Circuit Manifold

The brine circuit manifold merges the individual collector loops
of the heat source system into a single main pipe which is con-
nected to the heat pump. Integrated ball valves allow the indi-
vidual brine circuits to be shut off for de-aeration purposes.

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
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

CAUTION!
If the heat pump or circulating pump is controlled externally,
an flow rate switch is required to prevent the compressor
from being switched on when there is no volume flow.
