Change
1. Press key (T) for 5 seconds until the
display H6 flashes.
2. Press the key (T) to set the required value.
3. If the key is not pressed for 5 seconds, the
displayed value will be saved and flashing
stops.
NOTE: During the normal charging
process, the device divides the
charging current between battery 1
and battery 2 as set. Once the
battery 1 is fully charged, all the
charging current is fed to battery 2,
regardless of the set value. If the
voltage of battery 1 drops, the
charging process starts again. If only
battery 1 is connected, the entire
charging current is supplied to this
battery regardless of the set value.
PWM charging frequency
The pulse frequency of the device can be set
here. This may be changed to reduce possible
interferences.

Function display / troubleshooting
LED H1 (H2) shows the status of battery 1
(battery 2).
LED flashes in longer intervals:
Check connections from the device to the
battery and solar module, ensure that they are
connected to the right terminals.
Test the fuse, solar module and the battery.
LED flashes:
Battery is fully charged.
LED shines:
The battery is being charged.
LED flashes in short intervals:
The battery is not being charged. If necessary,
replace faulty battery.
LED does not shine:
Battery not connected or over-voltage.
If this does not solve the problem, please
contact the Truma Service Center.
Safety instructions
WARNING: Failure to observe any of
the below safety warnings may lead
to serious injury or even death.
• The solar module generates power when
light is cast on it. The full voltage is also
available even if there is little light. The
open circuit voltage may be twice as high.
Do not touch any live parts.
• Do not step on or place any loads on the
solar module.
• Do not drop.
• Do not use a damaged solar module.
• Only qualified technicians may assemble
and connect electrical devices
• Never switch solar modules in sequence, as
this could lead to higher voltages.
• Liquid electrolyte batteries can create
explosive gases, so ensure there is adequate
ventilation. Check the liquid level at regular
intervals.
• Overcharging can damage your battery;
check the technical data for your battery to
avoid this.
• Equalisation charging increases the
charging voltage. This may damage the
consumer unit. Ensure that all consumer
units are designed for such voltages.
