Hive Installation wiring problem

[Nick Hammond]

The above is a photo of my current Potterton wiring diagram. I’m trying to install a two channel Hive system. The issue i’m Having is with the live wire that runs into 5, can someone tell me what I should do with this? I’m sure I know what to do with the other wires but this is giving me a real headache. Thanks

The wire loop between L and 5 is to provide a live supply to the EP's heating switching contact.

The Hive has this link already made internally for you so no external link is required. That's why it doesn't have a terminal 5. Simply discard it.
