That said, my Potterton locked out again overnight, that's twice in the last 3 months. Heres hoping there is enough PCB to solder to, as I vaguely recall the last time - probably about 10yrs ago - I was having to rebuild tracks across burnt, disintegrated board. I suspect it will be a new PCB this time

My Vaillant has a huge pcb with another pcb piggy backed onto it, with looms of cable running everywhere ......
