Does anyone know of a good source of diagrams either on the internet
or elsewhere which will help me design my pipe circuits? I think I
understand what I need to do but seeing in a picture/diagram would be
worth a thousand words. I am especially puzzled or concerned to know
if I need to fit some kind of bypass system around the motorised valve
for either maintenance or summer running.

Although they are specific makers the parts are so interchangeable this
should be all you need.
PS if you're changing things consider "S" plan - it's better.
You don't normally need a bypass, the pump and boiler are called by the
valve opening, and can't start if there's no water path through rads
and/or HW cylinder
