3.2 Contact plate

ATTENTION!
Before opening the device, ensure that all electric circuits are
disconnected from the power supply.
The contact plate is in the top area of the indoor unit. After re-
moving the front cover, the electronics area is freely accessible.
The contact plate contains the supply connection terminals,
heating contactors, connecting terminals for the connecting
line to the heat pump and the heat pump manager.

3.3 Heat pump manager

The integrated heat pump manager is a convenient electronic
regulating and control device. It controls and monitors the en-
tire heating system based on the outdoor temperature, as well
as domestic hot water preparation and safety systems.
The enclosed operating instructions describe the functional
principle and use of the heat pump manager.

Transport

A pallet should be used to transport the heat pump to its final
installation location. The basic device can be transported with a
lift truck, a pushcart or similar.
ATTENTION!
The indoor unit is to be fixed to the transport pallet with
screws.
