8.4.3.1 Auxiliary relay parameters
A list of the auxiliary relay parameters can be found at the end of this manual in chapter 15.

8.4.4 Basic settings {14000}

8.4.4.1 Block manual programming (DIP switch) {14174} (No)
Blocks the operating mode chosen by means of the DIP switches inside the VarioString.
8.4.4.2 Battery charge current {14001} (120 Adc)
The VarioString tries to maximize the battery charging current up to its rated current; however, it is
possible to limit this current using this parameter for small capacity batteries. The current appropriate
to the battery is reported in its technical data. The value set by this parameter is used during the bulk
phase.
8.4.4.3 Configuration of PV modules {14002} (Automatic)
This parameter allows the selection of the type of cabling of the MPPT inputs. In automatic mode, the
VarioString makes measurements to determine the type of connection. You can also select
independent mode if you have two distinct PV strings that are not connected together. The parallel
cabling mode is reserved for the case when your PV string(s) are brought to the VarioString with one
set of cables and the two MPPT inputs on the VarioString are physically connected (cabling
accessories are available). The series cabling mode is used for PV strings with max voltage levels
higher than 600V; in which case the PV generator is connected to PV2- and PV1+, and PV2+ and
PV1- are physically bridged.
8.4.4.4 Restore default settings {14067}
Sending this signal restores the original values of the VarioString parameters.
If the installer has made some adjustments during the commissioning of the installation, this
function does not restore the factory settings but those made by the installer.
8.4.4.5 Restore factory settings {14068}
This parameter is accessible only when the RCC-02/03 is in installer level and allows the VarioString
parameters to be restored to factory settings.
