I moved into my new flat and the timer for the combi boiler wasn't working. I just unscrewed the front to take a look inside and it turns out the timer isn't wired at all. I can't find the installation manual for either the boiler or the timer to explain which wire needs to go in which terminal, and can't find this information online. It's a Baxi combi boiler and a Grasslin FM/1 ST H timer. There are 4 terminals and 1 brown wire, 1 blue wire and 2 black wires. I assume that brown = L, blue = N, black = Switch. Can anyone tell me which colour should be connected to which terminal? Images attached. Thanks!
