Hot water/heating issues. Doing my swede in!

Yes that's normal. It only shows 6 during combi mode or when using the cylinder sensor.

When you swap the head cut the wire from the old one off a few inches before the wiring centre then you can pop the new wires in one at a time

All these Intergas fanboys on here but where are they when you need 'em......

See @Razor900 posts... He's probably OK with this one on his own
