Fresh water tank
The level of the fresh water tank can be read off here. The alarm
can be activated (green) above the left soft key (On/Off icon). If
the alarm has been activated, a beep will go off when the tank is
being filled. These beeps will be sent at increasingly shorter inter-
26,4°C
vals while the tank is filling up. The level of the fresh water tank will
be automatically updated on the control panel every few seconds.
26,4°C
Exit this menu by using the "Back" function; otherwise, after one
hour, it will automatically switch back to the main menu on the con-
trol panel.
Battery management*
The current status of the battery is displayed in the battery menu
(self-sufficient package). The charging status is shown in the batte-
ry icon; the example shows a fully charged battery.

The value "R" shows the calibration check. If "1" is output, the sen-
sor will be calibrated (target state). If "0" is output, the measured
values may deviate slightly and the sensor should be recalibrated.
Normally, calibration is carried out automatically, whereby neither
the charging nor the discharge current may be more than 150mA.
Manually calibrating the sensor
The system can be manually calibrated
- while using the 230V mains operation or
- if no electrical device has been switched on in 12V operation.
To do this, the 30A main fuse must be switched off by pressing the
pushbutton on the battery container (see "7.4 Operation via bat-
tery"). Now the sensor can calibrate itself. This process takes ap-
prox. three hours. If the fuse is then switched on again, a value of 1
should be shown on the display.
The temperature of the battery must not exceed 50° C.
A warning message will be sent if the temperature ex-
ceeds 50° C and the battery will be shown in red in
the main menu on the control panel. If the battery is
overheated, it cannot be charged. Should this warning
occur repeatedly, the caravan must be taken to an
authorised specialist.
