RM7XX5 L - models are equipped with an
‘AUTO’ MATIC function.
1. Set energy selection switch (A) to position
‘AUTO’. The LED ‘AUTO’ illuminates.
Note: Manual operation is possible at
any time.
Explanations
Upon switching on, the electronics
automatically select one of the three possible
energytypes:230V-12V–liquidgas.The
control electronics automatically ensure that
the refrigerator is supplied with the optimum
source of energy in each respective case.
Priority 1. Solar(12VDC)
  2. 230VAC

4. Liquid gas
The selected energy is displayed by the
correspondingLED(i.e.230V).
230V - operation
If sufficient supply voltage is available (more
than200V),thispowersourceisselectedas
the first option ( no solar-system installed).
12V - operation
12Voperationshouldonlybeselected
while the vehicle motor is running or there
is sufficient voltage available from the sola
system. This can be detected from the D+
connection of the alternator to the electronics,
or from the respective signal on the solar
charge regulator.

Refuelling Stop
In order to prevent unintended switching to
gas operation during refuelling, the electronic
system starts gas operation of the refrigerator,
after the motor has been turned off for 15
mins. During this time the appliance is in
stand-by operation mode and only the ‘AUTO’
LED lights up
The use of naked flames is prohibited
in petrol station environments. If the
refuelling stop lasts longer than 15 mins
the refrigerator should be switched off at
the main switch (A), or switched over to
another energy type.
Gas faults at ‘AUTO’ mode
If gas faults occur the operating LED ‘C’
ashesyellow.
