Corinium Duo Isolator button

Hi, we have a new Peugeot based Corinium with a little button on the ignition switch for the vehicle battery isolator. Should we use this when not using MH, if we do and have it on EHU will it still charge the battery, cannot find anything in Peugeot or AS handbook

Can't answer your question, but I suggest you don't use the "Description" line when starting a new thread. It doesn't show on the page most members use, so your title could be fairly meaningless.

(It's a pain, but we are stuck with it!  )

I've fixed it for you. 

If you use the ignition button I think you'll have to reset your clock and maybe radio settings. It will also disable your central locking so you'll have to lock doors manually. Also I believe it will disable any alarm so if fitted your insurance company may not like it!

Thank you

If you don't isolate the starter battery and leave the van without being on mains hook up (with the EC500 switched on), after 2 weeks your starter battery will be flat and the van won't start. Peugeot installed the facility as the van electrics consume a lot of power when the van is doing nothing.

It’s normally on EHU when at home, just a “what does it do question really”
Do you main control panel on or EC 500 as I always leave that on.

There are lots of threads on the forum about problems with batteries in vans during winter storage and with batteries continually charged when in storage.


In summary; If you have an ehu available, are not using the van AND have an EC500 power unit installation, leave the EC500 switched off but once a week switch on the EC500 and connect hookup up for a continuous period of 24hr, switching off the EC500 when not charging.

Or put the EHU on a plug in timer switch which we have done for years without problem, ours gets an hour a night and batteries are always fully charged.

The EC500 does not split the charge between batteries. If Smart charge is enabled (default) It selects the one it thinks needs charge most and charges it for 4 hours, it then switches to the other and charges that for 4 hours. If you want to be certain that both batteries are well charged then you need 16 hrs but for convenient access times, I suggest 24 hrs.

Thanks Peter
I stand corrected!

according to the latest web site spec, the Corinium comes with an EC700 control unit and an 80w solar panel with the Premium Pack (every model?)...

assuming the ec700 is a lot less power hungry than the ec500, wouldn't the solar panel manage to keep all batteries fully charged without an EHU.

anyone tried the latest vans? worth a go to do away with a cable at home?

If you knew anything about Auto-Sleepers you would know that they don't start building new models till after orders are taken at the October NEC show. Its possible some new models will be delivered in March 2019 but that is not certain.

Peter, I was curious to see if the change in hardware had improved the situation...

so the polite response to my post from 'someone in the know' (like your good self) might be....no one has tried them as these units are only fitted to upcoming 2019 MY vans....

so why the need to post in such derogatory way?

I really hope the 2019 vans 'work better' in the solar department than previous efforts...

I'll await the news in Spring.

BTW, I know lots about AS....anyone reading this forum would glean much 'experience' of the brand....and it's 'foibles'.

Merry Christmas.

I did not read Peter's response as derogatory. I felt that the way that he expressed it was one of general disappointment that A/S trumpet innovation but are somewhat tardy in implementation of such improvements. In interpreting his remark in that way I would add that A/S are no different from other companies in having enthusiastic marketing departments.
Don't take it personally, Chris. From what little I know of Peter I am sure it was not meant in the way you seem to have taken it. :-)
