Hi all,
I am updating me CH / HW controller from a Potterton EP2000 to the Honeywell ST9400C, but am having issues working out the wiring...
The Potterton has 7 connections (plus the earth) and the Honeywell has 6 (plus the earth).
This image shows the wiring guide for the Potterton and how my system is currently installed -

And this is the wiring requirements for the Honeywell -

Could you wise / experienced members give me some advise on where the wires need to be relocated to accomodate the Honeywell?
Thanks,
Bob
