Wireing up a new central heating programmer

My old Randal 4033 has died, so ive bought a centaurplus c27 (as recommended)

But my electrical wiring knowledge is poor

The old randall wiring is here

and the new Centaurplus c27 wiring diag is here
http://www.horstmann.co.uk/downloads/ElectronicDocuments/Central-Heating/C21-InstallerGuide.pdf

Any heating/plumbing experts able to advise me, which wires go were from the randall to the c27
as I cant even start to work it out !!!

regards
steve

If you give me more details i will tell you how to proceed.

Is your system fully pumped? Or gravity fed on the hot water.

Do you have a three port diverter valve or one or two two port valves?
