Does anyone know contact details for MES. I have a problem with the control panel and I need to contact them to see if it's possible to repair or replace.

Try emailing Juie at [You must be registered and logged in to see this link.].

Very helpful, to a point, possibly will suggest sending unit in for a diagnostic check @ £95, repairs then on top of that depending on what they find.

My MES unit screen stopped lighting up, tried new 3v battery but no improvement. Luckily touch screen still works so I`ve persisted without repair - good luck.

I think you'd be better off phoning. Wanadoo emails no longer exist and meslimited.net is also unused and Domain for sale. If you phone it would be useful for our records if you could get a current email address.

Could you let us know the email address so it can be added to the 'useful contacts' sheet in the Factsheet section.

Control Panel Update

My Neuvo (which we had bought 2 months ago) had the MES digital touch screen control panel (mounted above the entrance door). It went totally dead, the screen would not show anything. I bought another (Reconditioned panel) from MES but that instantly showed up a blown fuse, the fuse was fine and the system it was feeding was working fine. I was checking things further and I found that 2 cables that feed the control panel had been cut and crimped togeather which I knew was wrong.

Anyway a long story short. I have now removed that control panel out of the system, and fitted a fully manual switched (8 switches) control panel on the side of the wardrobe with battery level indicator as well. Routed new cables as required from the PDU4m power distribution unit in the bed base. I must add that doing this operation is not a DIY fix (should you wish to do it). Unless you have a very good knowledge of 12v electrics, relays and cable ratings etc. which I luckly have as I used to work at A/S in the R&D dept designing the 12v and 240v wiring looms. I was involved with the introduction and wiring requirements of this Digital MES control panel. Even then whilst it was being developed I felt it was to complicated, delicate and would be prone to problems if in the future wiring loom alterations (for what ever reason) were done as it relied on the original loom to be complete (untouched) and fully operational. Anyway the powers that be had decided to use it and the rest is history as it's said.

My Neuvo is now working perfectly and I can isolate a system if it should go wrong and then trace the problem and fix it leaving the rest of the systems operational.

Happy days now.

I must add that I can not fault the help given my Julie at MES in the early stages of this saga. Email address if anyone needs it [You must be registered and logged in to see this link.].

Many thanks for an interesting post.  I wish I could do the same.

I wonder how you dealt with the display side, ie for external temperature and fresh water level, as these are the two bits that have gone wrong on ours.  The external temp constantly changes through widely varying figures, and the fresh water is stuck on low warning (with associated red screen and beeping).

We bought our 2007 Nuevo from a dealer in July. When we went to collect it the control panel failed. The dealer sent it back for repair.  On our first trip out it failed again leaving us with no water pump. Returned again for repair. to cut a long story short it is now end of September and booked in again as leisure battery not charging on ehu.

Knick-Knack, The external and internal temperature I didn't bother with as it is electronically linked to the touch screen display. To me if your warm sat inside thats fine if not put the heater on, if your cold when you go outside put a coat or jumper on! With the fresh water and waste water displays I fitted CBE units to each tank (one for fresh and the other for waste) which meant having to drop the tanks to fit them. In essence I made the system much more straighforward to operate and maintain. Now had 2 weeks in Scotland with it without any glitch at all.

Hazel and Mick
I would seriously think about getting it removed and a manual system as I have fitted put in. It's finding someone who can do it with the electrical knowledge is the problem. Once done though you can enjoy your Nuevo without the worry of the control panel crashing. You mention EHU did you mean a PDU unit (Power Distrubition Unit).

Hi, Hazel and Mick,
Just found this thread about the MES control panel and think maybe I have the same issue as you. It seems my battery is not charging when on hook up. Everything else seems to be working properly, therefore just wondered if you had the problem resolved and if so what was the issue and how was it fixed.
Many thanks,
Jerry

ArtNuevo.

This should only be attempted if you have 12v electric knowledge and are confident.

You should have in your bed base a Bonus Plug in Systems PDU 4M. This is the charger and 12v distribution unit. From the touchscreen unit when you change which battery to charge, inside the PDU 4M it triggers a 12v relay to direct the 12v charger feed to whichever battery you have selected. So if it's not doing it. First check that the charger is working and putting out a charge, this is not the easiest to do. One method is to note the voltage of both batteries with the charger turned off and then then check the voltage of both batteries with it turned on. one of them should rise. If so the charger is working. Next is to check if the relay is working, again not easy. Really the only way to check this is to unmount the PDU4M, (leave all the cable connectors connected) and look at the connectors underneath. Find the 4 way connector coming out of the unit. With a 12v multi meter check the voltage of the Brown/blue (output to the leisure battery) cable also the voltage of the brown/red cable (vehicle battery feed). With the charger turned on operate the touch screen to change which battery is charged and the corresponding cable colour voltage should rise, at the same time get someone to place a hand on the PDU 4M outside casing. They should hear/feel a small click if the relay is operating. If none of this happens the relay is either not getting a trigger to operate it or it is dead. To check the next stage you must be very confident and understand electrics. Disconnect the mains at source. Disconnect all the plugs going into the PDU4M and take the white outer casing off. Take the plastic rivets off holding the fuse bar and move it to one side (you may have to bend some of the casing). You will see a row relays along the bottom of the unit the split charger relay should be the second from the left. Remove the plug going to it and then remove the relay. With some cable put a negative feed to pin 85 and then have a positive cable and touch it to pin 86 the relay should click. Next with the multi meter set to continuity put one lead to pin 30 and the other to pin 87A you should have continuity. how switch the relay as just mentioned continuity should be missing at pin 87A and now be at pin 87. This means the relay is working fine. It then shows that the trigger is not happening from the touch screen. You may well have to send your screen back to MES to have it checked/repaired. Odviously reassemble everything when you have sorted it. This is why I removed it out of the system and replaced it with a manual system, everything is traceable and easily and cheaply repaired.  Like I said only attempt this is you have 12v knowledge and feel confident.

Hi Gollum
Thank you for taking the time to write such a detailed response. I’m ok to test the battery when charging etc but maybe dismantling the pdu4m maybe a bit beyond me. I have often thought of changing the MES for a far simpler system. But from what I understand the simpler functioning control panels will not work. I like the sound of what you have done. Did it take you long, I understand that you were involved with the 12v electrics on the Nuevo at concept. Do you know if a simpler control panel could be utilised with less work than you undertook.
Many thanks
Jerry

Hi All
Just found this thread after coming in from trying to bring the  touchscreen on my 2009 Nuevo ES back to life and failing big time. We were away at the weekend but had no use of the panel so no running water, flushing loo and only fob controlled lights etc etc.
We had heard an occasional bleep  on previous outings and noticed a blue flashing light behind the panel overnight but didn't worry! 
Removing the panel I found a crusty 3V battery which is now replaced but made no difference. After further investigation and fiddling to get a reset message(?) the lower (fob?) pcb snapped off, oops.
Should i contact MES for a replacement? confused3

You should e-mail [You must be registered and logged in to see this link.]

I got a prompt and helpful reply from her recently.

They will take the unit back for inspection and repair (or possibly replacement if it's too far gone).  

Give it a try.
