Descripton / Solution
• When the LED display will show
E0, means NTC (the temperature
sensor) broken circuit or short
circuit. Please contact the Truma
Service Center for support.
• Try on different power source
(vehicle or 100 V - 240 V AC
connector). If changing power
source fixed issue, then possible
issue with original power source.

pliance and battery is at least

tance is more than 2 meters use
at least 2.5 mm2 (AWG 13) cable.
