Hello everyone,
I recently bought a house which came with a Biasi Riva Plus HE 28C ERP Combi Boiler. I would like to install the BDR91 to the boiler but I would need some help with the wiring. Below is the manual of the boiler showing the connections for the external control.
and here is the actual picture:
And here is the wiring diagram for BDR1:
As the diagrams suggest, the link N should be removed from the boiler and 1, 3 should be connected to BDR91's A and B. Right?
How about the mains supply to BDR91? The boiler is powered directly from a fused spur isolation switch (cable coming out of the wall). I know this should be from the same spur switch. Should I use the N,L from the Boiler?
Many thanks in advance
