Okay, this is a long shot because it's a very specific question and this isn't a DIY forum, but I've seen that there are quite a few people on here who really know their onions, so I thought I'd give it a try. While trying to put on a new control panel for the electric underfloor heating in my kitchen, I managed to pull the end off one of the wires that come out of the temperature sensor. The bit I pulled off the green wire is the same as the end of red wire (except for the colour, obviously. Does anyone know whether it would be possible to reattach the end, or whether I can just strip some plastic off the green wire and use the internal wire directly to insert into the panel? This is why I should never be allowed to do DIY.
