Settings in the battery menu
Displaying/setting the
battery capacity
The nominal battery capacity "Ah nom" can be adapted e.g. on retrofitting a
battery. The setting range is between 50 Ah and 495 Ah (K100 value). The
standard setting ex works is 90 Ah.
Press battery button once briefly.
Press the "MENUE" button for more than 3 seconds.
The 1st page of the battery menu is displayed. The maximum battery
capacity "Ah max" is displayed.
Press "MENUE" button a second time.
The 2nd page of the battery menu is displayed. The display of the battery
capacity flashes.
Enter the new battery capacity of the living area battery with the "+" or "–"
button. It can be read off at the battery as K value. If no K100 value is indi-
cated, the K20 value can be read off and multiplied by 1.125.
Confirm the set value with the "OK" button.
To exit the menu, press any button or wait for 20 seconds until the display
automatically switches to the basic display.

Battery monitor
Automatic disconnector
The battery monitor compares the living area battery voltage to a reference
voltage. Monitoring is continued, even when the control and switch panel is
switched off.
Depending on the current drain an alarm message is displayed or the system
is shut down sooner or later. This improves protection against total discharge
of the battery.
As soon as the battery voltage falls below 10.5 V to 12 V (depending on the
discharge current), an alarm message appears in the display window. As
soon as the battery voltage falls below 10.5 V, all 12 V consumers are imme-
diately switched off. Only the frost protection valve is still powered. The con-
trol and switch panel also shuts down. Before shutting down, all switching
conditions and the battery capacity value are saved. The automatic discon-
nector is not triggered by short-term low voltage, caused by high current when
switching on consumers.
If an overload or an insufficiently charged living area battery causes the volt-
age to fall so low that the automatic disconnector is triggered, any consumers
which are not essential should be switched off.
You may be able to switch on the 12 V power supply for a short time.
Press the 12 V main switch button.
The 12 V power supply is switched on.
W
Changed values are only saved if the entry was confirmed using the "OK"
button.
If one switches to another display before pressing the "OK" button, the
changed values are not saved.
W
If no button is pressed for 20 seconds, the system automatically switches
back to the basic display that is not illuminated.
