Fault
Poor cooling, increase in
interior temperature.Com-
pressor does not run (bat-
tery connection).
Unusual noises.
Error indication
I
NOTE
• All errors are indicated by the error indicator LED flashing red (see chapter "Control and dis-
play elements" on page 13). The number of flashes depends on the type of fault. Each flash
lasts for one quarter of a second. After the sequence of flashes a pause follows.The sequence
for the fault is repeated every four seconds.
• In ECO, PERFORMANCE and FREEZER mode, an additional beep sounds.

Possible cause
There is an interruption in the battery –
electronics connection.
The main switch is defective (if
installed).
The additional supply line fuse has
blown (if installed).
The battery voltage is too low.
The battery capacity too low.
The cables are loose.
The contact is poor (corrosion).
The cable cross section is too small.
The compressor is defective.
A component of the refrigerant circuit
cannot move freely (touching the wall).
There is a foreign object stuck between
the cooling unit and the wall.

Suggested remedy
Establish a connection.
Replace the main switch.
Replace the supply line fuse.
Charge the battery.
Replace the battery.
Establish a connection.
Replace the cable.
Contact an authorized service agent.
Bend the component carefully away from
the obstruction.
Remove the foreign object.
Replace the fan.
Possible cause
The supply voltage is outside of the set range.
The fan load on the electronics unit is more than 1 A.
The rotor is jammed.
The pressure difference in the cooling system is too high.
If the cooling system is overloaded, the minimum speed of
the motor cannot be maintained.
If the cooling system is loaded too heavily or the tempera-
ture is set too high, the electronics can overheat.
Temperature sensor is defective.
