I thought I'd answered that?
230V N&L Supply to Hive N&L
One wire from Dual Channel Hive terminal 4 goes to the room stat terminal as highlighted in Red, the other room stat terminal shown in Purple isn't connected as per the diagram from the manual.
The only way it would have worked would be if the Dual Channel Hive was set to 'Gravity Operation' in which case, the Hot water terminal 3 is also made live when the heating terminal 4 is made live. It fools the Hive into switching the hot water terminal on whenever the heating is switched on.

The N & L are straightforward. And then the switched live terminal from the boiler (that has one of the black wires in) goes to Hive terminal 4. They are the only 3 wires needed. No links required. The other room stat terminal remains empty as shown in the diagram from the Logic+ Combi manual below.

Now I can see it shouldn't work but it does.
