3.2 Heat pump manager
The heat pump manager included in the scope of supply must
be used to operate the 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 temperature, as well as domestic
hot water preparation and safety systems.
Sensors for the demand and outside temperature to be in-
stalled onsite, including mounting material, are included with
the heat pump manager.
The enclosed operating instructions describe the function and
use of the heat pump manager.
