To set the nominal capacity of the living area battery, always enter the
K100 value stated on the battery. If no K100 value is specified, read off the
K20 value and multiply it by 1.125.
5.9 Battery monitor
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.
Alarm message and system shut down are dynamic processes, i.e. depend-
ing on the current drain, the 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 11.7 V, an alarm message is dis-
played (see the section 5.12 Additional messages).
As soon as the battery voltage falls below 10.5 V, all 12 V consumers are
switched off. Only the frost protection valve is still powered. The control and
switch panel also shuts down. Before shutting down, all switching conditions
and the battery capacity value are saved. The automatic disconnector 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, it is essential to
switch off all consumers that are not required.
You may be able to switch the 12 V power supply back on for a short time.
„
Press the left side of the 12 V main switch.
The 12 V power supply is switched on.
If the battery voltage remains below 11.0 V, you cannot switch the 12 V power
supply back on. If an attempt is made to switch it on, the 12 V indicator lamp
and the "V" symbol flash.
Fully charge up the living area battery as soon as possible.
5.10 Checking the tank level
Observe the "%" display on the scale. The tank level is displayed in 4 stages
0 % to 25 %, 50 %, 75 % and 100 % by the indicator LEDs. The illuminated
scale points indicate the critical zone in red, the normal range is green.
W
The tank levels must not be checked permanently. The sensors might get
damaged if used permanently.
„
Press the left side of the tank level switch briefly:
The water tank level is displayed.
„
Press the right side of the tank level switch briefly:
The waste water tank level is displayed.
5 seconds after pressing the switch for the last time, the display is switched
back off again.
