Hi I was told I could use a siemens RWB29 as a digital replacment for my old and very noisy switchmaster 300.
I followed new diagram and put mains feed (3amp fused) into live I have a twin and earth and a single live and a single neg connection from glowworm boiler down stairs, I put twin and earth live into connector 3 and pump live in 4 all my negs go into the N block as instructions illustraight, my problem is I have no clue as to where i put the single live cause when I put it in any of the lives it blows if I leave it out timer works but blows fuse after about an hour and also although pump works on CH no hot water comes out so i'm guessing my boiler hasn't got a live feed also the single live is not a permanent live any help would be appreciated thanks as programmer is very close to being at top of the garden in more pieces than i got it with.
