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 cooler is operated when the vehicle ignition is switched off, the cooler switches off automatically as
soon as 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.
