All sorted now.
I contacted the manufactures and was given the correct wiring procedure which is;
Plug in the boiler to an earthed socket, Remove the black link cable in positions 6-7, Connect common switch live from controller to position 1.
My electrician was amazed that it was that simple because from the wiring diagram it looks totally different.
Many thanks to all who helped with their suggestions.
