Schematic diagram for Potterton 407677 control unit?

I am having problems with the control unit (407677) in my 22 year old Potterton Profile 80e boiler. Does anyone have the schematic diagram for the 407677 ? Otherwise I will have to trace it out from the PCB, which will take a few hours.

Did you manage to draw it out? I cannot find a schematic on the web.
