The wiring in the 'chocolate box' in the airing cupboard relating to the stat are as follows:
Black stat wire conected to a bunch of other Neutrals
Red stat wire connected to 'CH on' in programmer
Green stat wire connected to white 3-port valve wire
I know I need to sheath the 'naughty earth', but how do I wire the stat?
Connection points are:
4 1 3 2
and wiring diagram says:
1 - Live
2 - Neutral
3 - Nothing
4 - optional to loop Neutral to both 2 & 4 and take in a resistor (or something?)
