Hi, I know there are already one or two posts but would like to check wiring before i hit the switch.
I’ve added the current wiring of the boiler DSC_2057.JPG.
LW Boiler Switch installation states:
L/N/E boiler to L/N/E Boiler Switch
NO Switch to RT boiler
COM Switch to RT boiler.
From image uploaded you can see RT is not an option.
Instead there is LR (heat) which is described as 230V switched live inputs CH.
My guess and from this video https://www.youtube.com/watch?v=iJ3nPK9ZSJs is that
1. The white wire link is removed between L (230V Out) and LR (Heating)
2. L/N/E fed from L/N/E (230V In) to Boiler switch
3. N (230V out) to Com
4. LR (Heat) to NO
Does this sound correct?
Thanks for any help.
I’ve done a bit more reading and found some info from Worcester Bosch.
I think now I have to use the high volt link on my LW switch linking Live to COM
Then COM connects to Live (230V out) and NO to the LR (Live Return).
This is shown in wiring.png extracted from https://www.worcester-bosch.co.uk/professional/support/literature/greenstar-i-combi-wiring-diagram
Any further comment welcome though.
Not much activity here Maybe I should go to the WB forum. My final setup looks like this. Slightly in conflict to the LW manual but correct to boiler.
