6. Setting the battery monitor to protect against low voltage
The cooling unit comes with a 3-level battery monitor that protects your vehicle
battery from excessive discharge when the device is connected to the on-board
electrical system.
If the cooler box is operated when the vehicle ignition is switched off, the cooler
box switches off automatically as soon as the supply voltage drops below a
certain value. The cooler box switches on again as soon as the battery is charged
to the restarting voltage.
Caution! There is a risk of damage!
After being switching off by the battery monitor, the battery is no longer fully
charged. Avoid repeated starting or operating without charging for long dura
-
tions. Ensure that the battery is recharged.
In the "H3" level, the battery monitor responds faster than in the "H1" and "H2"
levels.
If the cooling unit is powered by the battery after starting, select the battery
monitor level "H3". If the cooling unit is connected to a supply battery, the battery
monitor level "H1" is sufficient.
Switch on the cooling unit. There are 3 levels for the battery monitor setting to
protect against low voltage: H1, H2 and H3. Touch the "UP" and "DOWN" buttons
simultaneously for about five seconds. "H1" or "H2" or "H3" flash on the screen.
Touch the "UP" or "DOWN" button to select the battery monitor level "H1" or
"H2" or "H3" and to protect your vehicle battery.
