Hi Italianjob
Hope this will be of use!....
The Holdsworth Villa 3 manual states this:
The refrigerator can be used in three ways:
A) Via the vehicle battery when in motion by putting the 3 position switch on the refrigerator to battery pic symbol with + – and then operating the switch on the dashboard tunnel(the one in your photo) marked 'fridge'
B) The gas supply when the vehicle is stationary and the ignition switched off, by putting the 3 position switch on the refrigerator to '0' and then following the instruction manual.
C) By mains if the 3 position switch on the refrigerator is put to pic symbol of plug and a caravan hook up or other mains supply is available.
The 12 volt supply is from the main vehicle battery circuits and not from the caravan battery or the zig unit. There is a 25 amp fuse on the refrigerator circuit which is located in the fuse box in the main vehicle battery compartment behind the drivers seat (unless you have a diesel).
