Thanks Dean - I have a Greenstar Combi Boiler but I'm confused where the hot water part is coming from? I would have thought we'd have the same model...never is that easy is it!
On this link (WR1 = Drayton) (
http://www.draytoncontrols.co.uk/sites/default/files/Digistat1RFUIGuide.pdf) it appears to say:
N = Neutral (same as Hive)
L = Live (same as Hive)
1 = Common (same as Hive)
2 = Heating satisfied or call for cooling (is this Heating off?)
3 = Call for heat (same as Hive for Heating on?)
i'm looking at the Hive Single channel by the way
am i missing something really obvious?
