Sorry, I am only on at night after work.
Depending on the way your system is piped then the wire from the fused spur goes into N,L and Earth.
The wire for hot water on goes in to 3
The wire for heating on goes into 4
With the new backplate there is no need to link any numbers as the old programmer could work on volt free system whereas the new one cannot.
