Operation
Control and Display Panel
The display shows the actual data (level, voltage...) as numerical values. The menu level and the displays of the
board battery additionally show a bar graph on the left side. The measurement unit of the displayed value is also
shown on the display.
Marks (arrows) on the lower side of the display point to Board or Start, depending on the displayed menu.
The desired information is displayed using the control keys of the battery control, the tank displays and of the
solar computer. The adjacent LED indicates what kind of information is currently being displayed. To change the
display, such as between board battery and starter battery, press the key adjacent to the corresponding LED.
Use the arrow keys on the left side of the display to change to the next or previous page.
Control keys and remote control keys for display ON/OFF, main switch and pump relay. The LED lamps adjacent
to the keys indicate the corresponding state.
Display Illumination:
The illumination of the display is activated when pressing any key. It will be deactivated automatically after 3
minutes, if the main switch is switched-on. If the main switch is switched-off, the illumination will be
deactivated already after 30 seconds to avoid an unnecessary load of a potentially empty battery.
The illumination can also be switched-off manually by shortly pressing the main switch (see figure on the left side).
The brightness of the LED lamps is coupled with the illumination of the display. If the display is dark, the LED lamps will
also be dimmed to a minimum.
Brightness Display and LED:
The brightness of the display illumination and the LED lamps can be changed at any time by pressing
and holding (3 seconds) the arrows keys. The settings will be stored.
Main Switch:
The main switch will be switched-on or off by pressing and holding the ON/OFF key (>3 s). The state of
the main switch is indicated by the adjacent LED "12V". Please observe, that the main switch might be
switched-off automatically in case of low voltage (see battery protector).
If the main switch has been switched-off, the illumination will be deactivated already after 30 seconds.
Operation of the pump is only possible, if the main switch is switched-on. It will be switched-off automatically, as soon as
the main switch had been switched-off.
Water Pump:
The pump key switches the pump relay on or off. The state of the relay is indicated by the adjacent LED
"Pump". Operation of the pump is only possible, if the main switch had been switched-on. It will be
switched-off automatically, as soon as the main switch had been switched-off. The pump cannot be
switched-on, if the main switch had been switched-off. Should this be attempted nevertheless, the LED "12 V" will be
flashing for a short moment to indicate that the main switch is still switched-off.
