Automatic operation

To start the refrigerator, press button (1) for 2
seconds.
The refrigerator starts with the last selected
type of energy.
Automatic operation :
Press button(5) : A
Upon switching on, the electronics
automatically selects one of the three possible
energy types: 230V - 12V - liquid gas. The
control electronics automatically ensures that
the refrigerator is supplied with the optimum
source of energy in each respective case.
Sequence of priority:
1.) Solar (12V -)
2.) 230V ~
3.) 12V -
4.) Liquid gas
Note: If sufficient mains voltage is available
(more than 195 V), this power source is
selected as prime option. If a solar system
capable of powering the refrigerator is
installed, the solar 12V supply takes priority.
The 12V operation is otherwise only effective
while the engine is running.
According to the sequence of priority the
electronics selects GAS as energy source only,
if both of the electrical energy source are not
available.
Manual operation is possible at any time.
Note: For Setting of cooling compartment
temperature see point "4.7.2"

Refuelling while in AES mode operation
Note: 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 minutes. During this period

the appliance is ready for operation ("stand-
by"). The temperature level LEDs do not light

then while all other indicators remain active.
!
WARNING: The use of unshielded
flames is prohibited in petrol station
environments. Should the refuelling stop
last longer than 15 minutes, the refrigerator
has to be switched off or switched over to
another energy type.
Additional features (MES / AES)
• The brightness of the display reduces after a
WARNING!
few seconds if no other buttons are pressed.
The indicator lights again if a button is
pressed. Press the button again to activate
the required function.
• Failures are indicated by flashing of the failure
indicator LED.
• Should the door be kept open for too long
(more than 2 minutes), an acoustic signal is
initiated (pulsing whistle tone).
• Should the electronic control detect any
failure, an acoustic signal will sound (pulsing
whistle tone). At the same time the display
starts flashing (for trouble-shooting, please
refer to page 150).
Gas operation with internal batteries
(optional)
An optional battery compartment in the
electronics case for internal (self-contained)
power supply of the electronics is available
for the model variants RM 8xx1 and RM 8xx5
(appliances with electronics).
