Help with S Plan 3 BDR91 Wiring

Hi all,

I currently have an Evohome setup and my heating is an S Plan config. I'm looking for help confirming the wiring for adding a 3rd BDR91 controller into this setup in order to take advanced of some of the newer features in the latest beta software. These features aren't available when BDRs are only configured under the stored hot water config. The setup that I'm trying to achieve is

BDR 1 - Boiler Control
BDR 2 - Central Heating Zone Valve
BDR 3 - Hot Water Zone Valve

I've attached a diagram I edited from the Evohome manual but I wondered if someone could confirm that it's correct or point me in the right direction.
