I am hoping some of our trade members with access to Truma's technical department will be able to help.
When using the CP-Plus in the timer mode it fails about 30-40% of the time & you wake up to a cold van & no hot water.
When it fails the error is either E255H (no 12v to boiler) or E225H ( control lead fault) and occasionally E89H, when it fails there are no fault indications on the boiler LED's.
Contacted Truma and they said you have a 12v wiring fault take it to one of our agents, I had Premier Motorhomes look at it they said nothing wrong with wiring or connections, this I already knew as I had checked everything myself.
It appears to be a fairly common problem, my mates C6 in his Carthago is the same, search the web you will bring up the same problem on some caravan forums, search German Google you will find the same problem.
As Truma don't seem to want to talk to end users about can any of our trade members shed some light and hopefully tell me Truma are working on a software/firmware update for the CP-Plus.
And now to my second fault:
When the hot water is set to 40deg it fails to maintain the temperature, so if one of us has a shower it's too cold for the next one, or if you leave it on all day after 2-3 hours the water will just be luke warm then a further hour it will be hot again, it appears to have a far too higher hysteresis in the control circuit or sensor, it works fine set to 60deg.
When the van was at Premier they looked at this as well and the service guy said it's all working fine you shouldn't use it at 40, these new boilers are designed to only loose 1 deg per hour (how come mine looses about 10deg then!) this why they won't work at 40 (BS), when leaving the service manager said I hear you have been running your water at 40, nobody does that you have to run it at 60.
Now the C6002 in my last van I always ran at 40 without any problems, running at 60 is a pain in the bum, not only will I use more gas but more importantly it's a right pain to set the shower to the right temperature and wastes more water setting it.
Please tell me there is a fix for this.
Obviously Premier are only going by Truma's guidelines and they are a very helpful dealer, my gripe is with Truma why don't they come clean and admit they have problems with the C6 & CP-Plus most unlike a German company.
