3.3 Heat pump manager
The heat pump manager included in the scope of supply must be
used to operate the air-to-water heat pump in heating operation.
An add-on module (ACU WPM) expands the function of the heat
pump to include the "cooling" operating mode.
The heat pump manager is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system based on the external temperature, as well as domestic
hot water preparation and safety systems.
The customer must install the external temperature sensor which
is included in the scope of supply of the unit heat pump and heat
pump manager together with the necessary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump manager.
