Wiring a horstmann RF ASR-ZW to a potterton performa 28

[Shugscot]

Horstmann have already told me unit is compatible. Just wanted to check connections. As per the attached diagrams link removed on the boiler terminal 1 on the boiler to terminal 4 on the rf unit and terminal 2 on the boiler to terminal 4 on the RF unit. Both diagrams attached and have used the recommended 1mm 5 core heat resistant cable

Can anyone confirm I'm right before I power it up? Cheers

No the other way round boiler 1 to stat 2. boiler 2 to stat 4.

Plus you need a fused supply to the stat preferably from the same supply as the boiler
