3.2 Switch Box
The switch box is located in the heat pump. It can be swung out
after removing the lower front cover and loosening the fastening
screw located in the upper right-hand corner.
The switch box contains the supply connection terminals, as well
the power contactors, the soft starter unit and the heat pump
manager.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system on the basis of the external temperature, including hot
water preparation and safety systems.
The customer must install the external temperature sensor,
which is included in the scope of supply of the heat pump man-
ager together with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.

Accessories
4.1 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 is made using a 6-core
telephone cable (special accessory) with modular plugs.
NOTE
In the case of heating controllers with a removable operating element,
this can also be used directly as a remote control.

4.2 Building management
technology
The heat pump manager can be connected to a building man-
agement system network via supplementation of the relevant in-
terface plug-in card. The supplementary installation instructions
of the interface card must be consulted regarding the exact con-
nection 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 pump is controlled externally, an
additional flow rate switch is required to prevent the compressor from
being switched on when there is no volume flow.

Transport
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
Use a wooden pallet for transporting the heat pump to the final in-
stallation location. The basic device can be transported with a lift
truck, hand truck or by means of 3/4" pipes fed through the holes
in the base plate or frame.
The heat pump and the transport pallet are joined by four transit
bolts. These must be removed.
Before using the transport holes in the frame, it is necessary to
remove the lower side panel assemblies. This is done by loosen-
ing each of the two screws at the base and then withdrawing the
panels by unhooking them from above. Rehang the panels by
gently pushing them in an upwards direction.
Be careful not to damage any components when inserting the
pipes through the frame.
At the installation location, 8 black dust caps, which are included
in the packaging of the device, must be snapped into the trans-
port holes.
