I've only fitted Hive smart controls but imagine it's similar. Remove the 24v bridge and wire the heating on signal to RT. That's on the plug next to the green mains plug for the boiler. Should be piece of cake.

That's what I was thinking but don't want to cross the polarity or does it mate no difference?

You're not wiring in to the bus connectors so polarity isn't an issue
