help with worcester boiler

[aravensdale67]

when i turn on the boiler on to hot water only the radiators come on fully, i have changed the 3 port valve already

Did you change the entire valve?

Did you fit it the arong way round?

Do you get hot water only when you select central heating only?

hi, i changed the whole valve, and fitted it the right way. everything else seams fine but when i turn on the hot water the rads come on as well? it is as if there a crossover somewhere could it be a another valve that could be fitted wrong? i did not install the system

What was wrong with the original valve?

Drayton valve by any chance?

How did you determine which way round it should have been fitted?

The two outputs are marked "A" and "B", which does each point towards?

Of course the wiring has been installed correctly.... No chance of getting the signal wires backwards
