7.1 Operating concept of the solar charger
The solar charger is equipped with a digital information and
analysis system (DIA system). If additional settings are re-
quired, which have not been configured using the installation
assistant (see Start-up (→ Page 18)), additional parameters
can be viewed and modified using the DIA system.
The operating concept and operation of the solar charger
are described in the → operating instructions of the
auroFLOW plus solar system. The read-off and setting
options at the operator level are also described in the
→ operating instructions.
An overview of the menu structure at the installer level is
included in the appendix (→ Page 29).
