Just bought a 2010 Adria caravan but am a bit disappointed with the heating. Just back from a few days away where the temperature was pretty low and even with the temp setting at 9 it still didn't get very warm and the thermostat wasn't kicking in. On my old ABI van, I had similar problems and got around it by fitting a remote sensor. Can you fit the same to this heater? Looking through the docs that came with the van it appears to be a Trumatic S 3002 P / S 3002 / S5002. I can't see any model number on the from at all.
