Zig cp400 in my ford transit camper-van
Excited as I was with my new (13 years old) camper-van, I was totally bemused by the Zig cp400 control unit. What did it do? How did it work? Would I disappear in a cloud of smoke or the camper van burst into flames if I pressed the wrong button?
If you are the proud owner of a rather ancient or not so ancient camper-van and are wondering what the buttons might be for, these few notes might just be helpful.
My zig cp400 has a rocker switch on the left hand side that has three positions selecting options for putting electric power through to the habitation area of the campervan
1) from the car battery (switch up)
2) no power (switch middle)
3) from the leisure battery (switch bottom)
To the right of this rocker switch, there are two led’s which show the status of the battery selected as either green (OK power) or red (low power).
On the right hand side of the Zig cp400, there are three switches that have two positions each. These apply the power from whichever battery you have selected with the aforementioned rocker switch to the individual circuits.
These are:
1) pump
2) lights
3) aux
In my camper van,
1) the pump referred to is the cold water pump from the built in fresh water container under the van which goes to the sink.
2) The lights referred to are the lights in the main living area.
3) The aux was unwired but I’ve now used it to provide 11 volts power to two extra lighter sockets for things like radio.
Although I have an external hook up, it doesn’t seem to be connected to my Zig. Instead, it runs through a circuit breaker to three 13 amp sockets that are scattered around by camper.
I hope this helps.
From what I hear, different camper vans are wired up differently and, if you are in doubt, consult a qualified automotive technician and I accept no liability if you disappear in a puff of smoke after reading this article 
Bye for now
