Hi
Hoping you can help, please.
I have just had my old thermostat and programmer replaced with digital ones.
Due to the "wonderful" wiring when my original boiler went in (wire starts off grey in the boiler, ends up blue in the airing cupboard), the plumber can only get the heating to work if the 3 port valve is set to manual permantly.
Not knowing what the 3 port motorised valve does, i wondering if anyone could explain what impact this has please ?
Many thanks
Jason
