Fascinating that I've just spent upwards of £200 to be able to do on my (newish) Carthago what I could do on my old 2007 Hymer, namely switch on the heating from the bed! Change isn't necessarily progress . . .
On the other hand, we no longer have to break our necks to set the CP+ control which is mounted above the habitation door. Bifocal specs do NOT help! All-in-all a satisfactory result: paid £195 delivered from eBay, brand new but without any instructions, but they're on the web, so no worries. We didn't want to monitor gas (have two alugas bottles) and don't have aircon etc. In fact it all brought a big smile to my face when I switched on the heating by text, and got a polite one back telling me it had done the business.?
