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 R134a 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 load current and the control volt-
age must be installed by the customer.
The brine pump is activated via the switch box. It must be
equipped with a motor protection device, if required.
The customer must provide both the heat source system and
the brine circuit manifold.

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 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 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

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.
