Ready for the rewire - last QA please

Glow worm Micron FF50 Boiler

I previously posted question and now have all the parts etc so have described what I'm going to do (more for a sanity check)

and will be wiring to my

HVAC Wiring Centre, Honeywell 42005748-001 - http://uk.rs-online.com/web/p/hvac-wiring-centres/2001342/

and a couple of questions about links at the end



Honeywell Cyl Stat - C,1,2 to Wiring centre C,1,2
Honeywell Thermostat - E, 1,2,3,4 - to wiring centre - E1,2,3 (no 4 in the centre) to just use the 3

Mid Pos Valvel - Grey, Blue, Orange, White to the same on the wiring centre (wiring center has a brown but Valve does not)


Boiler just has E, N, L wires (as in the 3 of them) so in wiring center assume I just use L N and E

Live feed is obvious

Now we have the programmer which seems straight forward

L, N, HW On, Hw Off, CH On - to its counterparts in the wiring centre

So whats left ahh, which links to cut and here I get confused

I think I use the Y plan (mid posn valves) so cut links L4 and L5

and I have read the boiler manual and it does not talk of pump overun anywhere so I guess I ignore that bit

thanks in advance

Thanks for the response so my research has paid off (nearly)
as for the query
Mid Pos Vvalve- from the valve there is Grey, White, Orange, Blue and Earth (its a 5 core cable) there is no brown
so they go to the corresponding place in the wiring terminal on the right below the pump - there just wont be a brown ?

Hi

finally ready, just one more question about the Mid Posn Vave connection, the wiring center can accommodate up to 6 connections, my valve only has 5 wires - there is no brown - i assume this is not an issue ?

so all connected but there is an issue, Hot water is fine, CH is not, when I turn up the thermostat I would expect the pump to start and the valve to move - neither of these things happen ?

Are there any checks I can do to see where the issue is ?

Regard
