I'm planning on updating our central heating system in the next few weeks and need some advice in regards to rewiring for the new central heating controller.
We currently have an ancient Potterton EP2000 unit controlling the central heating and I'm looking to replace it with a Honeywell T6R-HW.

My plan is to rewire the Neutral connection block, the Earth connection block and terminals A & C like-for-like into a Choc Box/Wiring Centre behind the old backplate. But I'm a little lost when it comes to migrating the controller wiring!
Can somebody help explain how to migrate the wiring from terminals 1,3,4 and 5 on the Potterton to terminals A, B, D and E on the Honeywell?
As best as I can tell, it would be:
Live feed to A with a link to D
Terminal 4 on Potterton migrated to terminal B on Honeywell
Terminal 3 on Potterton migrated to terminal E on Honeywell
But what do I do about terminals 5 and 1 on the Potterton unit? How would these be wired in relation to the Honeywell unit?
Thanks.
