Wiring a Hive Receiver to Worcester Bosch Greenstar 4000 30kw

[Stubow]

Hi Everyone - despite my best efforts I can't seem find a clear answer on how to wire a single channel Hive Receiver to a Worcester Bosch Greenstar 4000 30kw. I've attached 2 photos showing the connections on the receiver and boiler. With great hope you experts out there can help - thankyou!

Looks like extra low voltage of 24v isn’t supported unless you use Worcester accessories, so you need to provide a permanent live and permanent neutral plus switching. Looking at the diagram on the left of your Worcester attachment (240vac) you might be able to use one of the L out and N out, then link L at hive receiver to terminal 1 (common) and then take a wire back to LR. So best using 4 or 5 core flex.

It’s on the 240 v side

240 out goes to your controls
Lr is your switch back eg fire

So 240 out block
L to L on hive
N to neutral

On hive link L to 1
3 to Lr on boiler block
