Hi all,
I'm just wondering if you could give me some help with understanding the wiring on my combination boiler and thermostat.
I have a supply direct from the CU for the combi, this feeds into a SFCU.
There is a T&E to the thermo stat which is situated downstairs.
The wire from the combi is 4Core and Earth. Blue, Brown, Black and Black with the earth.
Here is a picture of the combo wiring.
1) Can anybody help me with what the terminals 3 and 4 are in the combi (The two black wires)
2) What wires for the 4 core and Earth connect to the live and neutral to the thermostat
thanks in advance.
