control panel

hello , we are off next w/e for a few days at a local campsite , what do I switch on to drive there on the panel , the fridge switch I know ,have tried it , lights ok , but the left hand switch hab/vehicle do I switch that on or leave in neutral .
on my old fiat ducato there were a few switches I had to put on , rather than drain the battery .
this one not sure of .
thanks mike

When you start the engine the panel should be disabled so all the hab functions do not work. Switch the fridge on to 12v operation, so the engine electrics keep it cooled.

thanks, how do you disable the panel then , so nothing should be on  and what switches do I put on when I'm connected at the campsite .I take it the fridge switch is the only one then

Difficult to answer since we have no idea of the model or age of your van.

It would help a lot if you included those details in your profile.

its a 2005 duetto , sorry was replying to ploughlin , who mentioned just the fridge switch when you are on the move

hi           If it's a 'plug in system panel' maybe turn of master switch on panel,when on site turn back on, turn on pump n lights,if on ehu select hab or veh to charge relevant battery,light fridge for gas or switch fridge for 240 v job jobbed,or forget all that as panel is dead when engine on,      Dave h

Switch on charger and leave rocker switch to hab. That rocker switch simply directs the charge from the charger to whichever battery you choose. Only switch it to eng (or vehicle) if you think the engine battery will need charging

Just to add to this confusion..............put the main switch on the panel to on. Leave it on. This will give power to all internal systems except the fridge when the engine is not running. When the engine is running it automatically cuts power to all habitation systems except the fridge and the hab battery. Put the red fridge switch to on and leave it there, the battery charge is automatic and needs no switch.
If you have EHU (electric hook-up) connected, the green switch on the fridge will need to be on. Leave it on. The rocker switch will direct charge to either chosen battery. Default, put it on Hab. Leave it on Hab unless the engine battery needs a boost.
If you do not have EHU at the campsite, the fridge must be run on gas. All other systems are dependent on the hab battery.  Hope this helps, but I do recall a late colleague once saying
"Well I'm still confused but now at a much higher level"    Keith

Mike  Your PM to me.  Put all switches on, including both fridge. Put the rocker on hab.
Everything will happen automatically whether on engine or not on engine.
