Hi
I wonder if anyone can help me with the wiring of my boiler…………
Newish Worcester Greenstar 30CDI, new Horstmann programmer.
The boiler worked fine with all its power coming from the programmer – live, neutral, earth – these were the only wires to the boiler. Then the Bosch engineer came to fix a leaking air valve and mentioned in passing that the wiring was incorrect – the boiler should have its own connection to a fused mains supply. So I did that, but that left a problem with the programmer. I still only have the 3 core wire coming from the Horstmann but the Greenstar requires 4 wires –
from the manual: connect S junction box LIVE supply to terminal Ls
connect S junction box LIVE return to terminal Lr
connect S junction box NEUTRAL to terminal Ns
earth to earth
so what goes where?
S-plan, 3 zones + indirect water, all with 2 port valves.
all sugestions appreciated
