this is really simple if you have internal clock on your boiler you need to drop the front flap on your boiler with the lights remove the back and on the left hand side you will see the wires go in to the boiler live neutral and earth, just above them is a red link you need to remove the link and connect 1 and 3 from the stat to these terminals in any order it doesnt really matter and 2 from your stat to neutral
