MES control unit switching itself on and off.

We have a 2008 AS Symbol with a ( factory fitted ? ) MES touchscreen control unit which sets up all habitation functions like the water pump, interior lights, etc, etc.
It is easy to both switch on when on site and switch off when in storage but, unfortunately, it regularly both switches itself off and switches itself on. For example, when getting up in the night we find it`s switched itself off and we have to use a torch rather than just switch on an interior light. Similarly, when in storage, having switched it off, we check a couple of days later to find it`s switched itself on, the `low water` alarm has been flashing and has drained the leisure battery.
The van is still under warranty and has been back to the dealer who said the control unit is working OK and they didn`t observe it switching itself off while with them. ( It immediately `played up`again after trip to dealer ! )
I have to take it back for some other `snagging` issues and will raise this again.

Any ideas, advice etc most welcome.

I have Warwick with mes control panel it some times turn it self off never turns it self on do you shut it down completely so screen is blank if I just shut down but leave autosleeper on screen it will turn on if water tank empty dealer could not find out why

Yes, when I turn it off the Autosleeper text disappears the screen goes blank and a few seconds later it bleeps to signal it’s completely switched off

I think there is a rechargeable battery in the back of control panel my panel turns off more if I have not had on hook up and used for a while I have a spare panel for when it goes completely read on here they have problems and someone had a New panel for sale on here think there is some were you can send panel for repair saw address phone number on here

I think these are the people to speak to. I can’t speak from experience, our MES panel on a 2009 Symbol behaved itself but I’m sure I’ve seen references on here to Apuljack repairing them.

How do you turn off the AS text and get a blank screen?

I would love to be able to do that.  I didn't know you could.

When Autosleeper is shown on the screen, press down the on/off button for a few seconds until the text disappears. Let go the button and after a few seconds the pad beeps once, I assume to confirm it’s off ?
To switch back on just press the same button and text reappears etc.

Sorry, just noticed you have a Nuevo, so MES pad may be different to ours on our Symbol ?

It's actually a CR1620 button cell not a rechargable. Are you totally turning the control panel Off. One press and Auto=Sleepers is still displayed to totally turn off you need to press the central button until Auto-Sleepers disappears.
