3.2 Contact plate

The cover must be removed to allow access to the inside of the
device.
The two screws on the bottom must be loosened for this. The
cover must then be removed to the top.
CAUTION!
Before opening the device, ensure that all circuits are
disconnected from the power supply!
After removing the cover, the electronics area is freely accessi-
ble.
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.
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.
