The installer was indicating a cable needed to run from the zone valve to control the boiler.
What you describe doesn’t require a cable back to the boiler, I think just wiring the high limit stat in series between the DHW BDR91 output and the DHW zone valve.
Yeah, that's what I said. A cable back to the zone valve.
This is obviously dependant where your zone valve is.
