8 Configuring the controller
The following section describes the configuration settings that can be
performed on the controller.
8.1 Accessing and changing settings
Pressing and holding the left button for at least 3 seconds brings you to the
first settings window (Operating mode). Further pressing of the left button
displays other windows. After the last window, the first window is displayed
once more.
Press the right button when you want to change settings in the currently
displayed window. The display then starts flashing. You can now use the left
button to select different settings. You must press the right button to save
the settings you have made. The display then stops flashing.
You can return to the normal display by waiting for 30 seconds or by press-
ing and holding the left button for 3 seconds. This applies to all windows.
The settings are retained when the battery is disconnected.
8.2 Operating modes
The device is supplied with SOC control preset. This means that the charging
method and deep discharge protection are controlled by the calculated SOC
value. If loads are directly connected to the battery and not to the controller
or the battery is also charged from a different source, then the Voltage
control (with bar display) operating mode must be selected. Otherwise, the
SOC calculation may be incorrect.
Notes on the
Voltage control with bar display
operating mode:
• Each of the 10 bar segments represents a particular voltage. The voltage
values are described in Section Technical data, Bar display scaling.
• If the voltage lies exactly between two bar segments, then the display
may jump back and forth between the two segments.
8.3 Setting the battery type to Gel / Liquid
The default setting is "Li".
Setting the battery type
affects the final charge
voltage of the controller. If
you use a Gel or AGM battery,
then you must set the battery type to GEL.
Please note: An incorrect battery type setting can damage the battery!
8.4 Night light settings
This setting offers three possibilities in the following sequence
• OFF: The function is deactivated (default).
• Load switch-on duration selection from 1 to 12 hours (lower middle Fig.).
• ON: The load output remains switched on all night.
