Accident! It just came away.
Just checking . . . .
A single white wire with three smaller wires - blue to 7, yellow and green to 8 and brown to 6.
2 separate blue wires one connecting 1 and 7.
One from wall to 4.
A separate yellow and green wire to 2.
Numbers 3 and 5 have no wires in them and we were able to have just heating before.
No. No motorized valve there.
We have a general thermostat in the hall and there is one on the boiler but not on the cylinder in the airing cupboard.
Yes. Now we can't get the hot water without the heating.
Nothing works at all!
