In >
Automatic Mode
< the
AES
electronic
system automatically selects the most efficient
energy supply. In automatic mode the electronic
system uses the D+ signal () of the
alternator to detect
12V DC
.
12V DC operation
is selected only while the engine is running in
order to prevent battery discharge.
Provide a 16 A fuse to protect on-board 12 V
circuit.
In order to ensure that the 12V power supply is
shut off when stopping the engine (otherwise the
battery would discharge within a few hours),
perform the power supply to the heating element
(connection A/B in wiring diagram) in a way to
have the 12V supply only live while the vehicle
ignition is switched on.
The connection C/D (interior light, electronics,
cable black / violet) must be permanently provi-
ded by a 12V DC power supply to be protected
by a 2A fuse.
If the appliance is installed in a caravan
the respective leads for the 12V+ and
12V- connections A/B and C/D must not
be connected to each other on the cara-
van-side .

For MES and AES it is compulsory to provide a permanent 12V DC supply at the ter-
minals C/D (permanent voltage supply for functional electronics).
