Glow worm ultimate 70ff wiring??

[Robbai]

Can anyone help, i have a Gloworm Ultimate 70ff boiler, the system is Danfoss Heatplan with Prorgammer (2 x 2 port valves) according to the Heatplan wiring the boiler only needs Live, Neutral, Earth and a single Pump supply wire, also another wire if boiler needs a permanent live which i do not think it needs??? my question is, the boilers wiring diagram shows L,N.E supply from mains, L,N,E to the pump and two wires from the Programmer with the note * REMOVE RED LINK AND FIT SWITH LIVE FROM PROGRAMMER the two wires are connected to 1 x Thermostat/pump overrun and the other to the main pcb. i hope that this makes sense. can anyone tell me what the correct wiring should be as there is confusion between the Heatplan and the Boilers wiring diagrams

if the question is about the pump, then the N & E can come from either the boiler or the wiring center but the live needs to come from the boiler.
the permanent live i think provides power for pump overrun but check the MI's to be sure

Hi
Thanks for the reply, i think that i am okay with the pump looks like it just needs a live from the pump to the boiler, also it looks live the boiler gets its live feed from the orange wires?? the main one that is confusing me is the switched live from the programmer surely the switching comes through the system prog,stats,valves and not directly to the boiler, but if so if nothing is connected to the pcb and Thermostat connections will the boiler work, sorry if this is confusing but difficult to explain.

valve/s orange wire/s go to switched live on boiler
permanent live goes from 1st Live in wiring center(same terminal as power from main FCU/switch and timer live power)to P/L on boiler (to provide power for pump overrun)
Pump Live goes from pump live on boiler to pump (not pump to boiler )

Hi
Is there any way of copying photos onto this forum, i am still confused, i am trained in electrics but the workings of my central heating has got me pulling my hair out, problem is it has been wrong for 10 years pump running non stop water always hot, i have worked out that the wiring is in a complete mess, i know how to rewire but unsure about the boiler wiring.
