This is a basic wiring diagram for wiring an 'unvented cylinder' with an evohome Hot Water Kit BDR91 wired to it.
The B & A terminals on the Unvented Cylinder may be labeled differently, so always consult the manufacturer's instructions for the supplied cylinder.
I hope that helps, but any questions please ask below.
Kind regards,
Richard
