Glow Worm Ultimate3 Stat Wiring

[Marbar2k]

Hi, can anyone clarify wiring and Honeywell 927 and BDR91 to a glow work ultimate 3.

The BDR91 is currently set up as a 240v feed with 4 core cable.

LNE are going straight from the receiver to the boilers LNE. I then have L bridged to A in the receiver. Does B from the receiver just go to RT on the boiler next to LNE?

Does the volt free loop need removing on the boiler from RT too?

Alternatively to wire it volt free. Does the link in the receiver from L to A need removing then run some 2 core from A & B in the receiver to the RT volt free side removing the wire loop?

Thanks.
