I'm trying to install Hive active heating. I have a Glow worm Easicom 28 combi-boiler which is currently connected to a Salus ERT20RF receiver.

I was hoping that somebody might be able to confirm whether the wiring I plan on doing is correct. I'm basing this on this thread:

The Hive active heating wiring requirements are:

The wiring for my current system is:


So the plan is:
Wire the current terminal 4 to the N terminal on the Hive unit
Wire the current terminal 3 to the L terminal on the Hive unit
Connect the L terminal on the Hive unit to terminal 1 of the Hive unit
Terminal 2 of the Hive unit is unused
Wire the current terminal 1 to terminal 3 of the Hive unit
Terminal 4 of the Hive unit is unused

This is what that looks like according to the previous thread:

I guess it is the lack of any cable at terminal 2 on the Hive unit that is throwing me.

If anyone could confirm that this seems right, that would be much appreciated.

No connection to be made to Hive 2. Your system doesn't need it.
