Heatslave 2 hive single channel

[R3su]

Hi all

Looking for some advice in connecting a hive single channel to a new heatslave ii.

Everywhere I look suggests the common (black) should connect to ‘LS’ which I don’t have.
If I connect to LR water, nothing happens. Do I need a jumper between common and live?

Thank you

Is this what I need to do?

Make a link between L& terminal 1 on the hive
Terminal 3 to LR with the radiator sign at the boiler
Simple as that

Thanks @ianmcd ! So the common isn’t used on the boiler side?

If you mean the black link in your pic between L&LR HW then unless you are using an external HW control then that link stays in, has absolutey no bearing on the single channel hive wiring though, the single channel Hive is simply a switch for the CH

Ah I see. Thank you.
So do I restore the link between L and LR (tap) on the boiler?

Some boilers provide a Ls (Live supply) and Lr, and some only Lr (Live return) for 230vac switching, no idea why this is becoming common practice as some thermostat/receiver terminals you struggle to get 1 wire in let alone any others

It does seem to be something that a jumper could solve rather than jamming multiple wires into single wire terminals.


Heating now fires!
I think I’m correct in restoring the factory link from boiler L to boiler LR tap.

If that’s how it came, do it. Consider this, if the boiler fires for hot water, it might not be needed.

yes
