Worcester 30CDi Wiring plus UFH queries

Hi all

I am in to process of installing the controls for a WB 30CDi system boiler with s-plan using two honeywell two port valves and a Honeywell ST9400C programmer.
Could anyone clarify the correct connections within the boiler. I understand that the live supply from the fused spur goes to the L & N in the boiler. Is it corect that the Ls terminal in the boiler is then connected to terminal 1 (in the wiring centre), and Ns goes to terminal 2 and Lr goes to terminal 10.

I am then hoping to control a single zone of UFH using a Heatmiser PRT (supplied with the UFH equipment). Does anyone have any information on how this might be done.

Thanks for any help.
