Power contactors, a soft starter unit and the extended controller
unit are located in the switch box. It monitors and controls all heat
pump signals and communicates with the heat pump manager.
Communication and control or mains cables, which are to be
routed apart from each other, are fed through the cable gland
area on the baseplate. The connecting terminals can be ac-
cessed directly by removing the side cover.

3.2 Heat pump manager
Use the heat pump manager included in the scope of supply to
operate the (reversible) air-to-water heat pump.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system based on the outdoor or room- temperature, as well as
domestic hot water preparation and safety systems.
The sensor for outside temperature to be mounted on-site incl.
fixing materials is included with the heat pump and heat pump
manager unit.
The enclosed operating instructions describe the function and

Accessories
4.1 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 inter-
face (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.
4.2 Building management system
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
