Our flash timer switch for central heating broke!
I got a digital programmer to replace the flash timer. I was doing the wiring and have gotten to the point where the heating can stay on however I cannot get it to turn off! I gather it's to do with my wiring!
Attached is what has been done so far....if anyone can lend some advice please it would be great....the cable coming from the isolation switch is a 3 core....the one going out to boiler is a 4 core...
