Replace BDR91 with Hive receiver

[PCAB939m]

Hi can anyone help? I would like to change my BDR91 to a Hive single channel receiver. My boiler is a Glow-worm Betacom 4 combi boiler. In my BDR91, cabling is as follows
N - Blue
L - Brown
L - empty
A - Black
B - Grey

So to install Hive receiver is the cabling as simple as
Blue to N
Brown to L
Black to Hive Com 1
Grey to Hive Heat 3

Yes, it is that simple!

Plus, the green/yellow wire can be parked in the Hives earth terminal.
