Mend Digistat SCR Boiler Thermostat Worcester Bosch

How do I wire a Digistat SCR unit into a Worcester Bosch CDI boiler?

I can see that I need to connect the Digistat SCR N & L mains to the ST10 block N & L and the SCR terminal 1 (thermostat live supply ) to the boiler's ST10 Ls (live supply terminal), but do I connect the SCR terminal 3 to the ST10 Lr (live return) or to the Ns (neutral) ?
