Refrigerator operation
Upon switching on, the electronics automati-
cally selects one of the three possible energy
types: 120V - 12V - liquid gas. The control elec-
tronics automatically ensures that the refrigera-
tor is supplied with the optimum source of ener-
gy in each respective case.
Sequence of priority: 1.) Solar (12V -)
If sufficient mains voltage is available (more than
60 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. The appliance
electronic system features a low-voltage
mechanism. Once the voltage drops below
10.5V, the appliance shuts down (manual
mode) or switches over to a different energy
source (AU mode).
