ELECTRONIC CONTROL
The device is equipped with a multi-level battery monitor that protects your vehicle battery against excessive
discharging when the device is connected to the on-board DC supply.
If the refrigerator is used with the vehicle engine switched off, the device switches off automatically once the
supply voltage falls below a set level. The compressor will start up again automatically in a few minute when
the voltage goes back to normal values.
Note: these values are measured at control unit input and/or on the DC socket.
