Y-plan help needed urgently...

[_lee_]

Hello guys i dont know if you will be able to help me with this but i have just replaced 3 port valve & rewired the system to the honeywell diagram.
i should say that all components in the system are honeywell apart from the tank stat..

Here is my problem.
everything is working as it should heating /hot water. But with heating & hot water off i can still make the boiler fire up by turning the tank stat dial to 70 degrees..i dont think it should do that, its going to overide the hot water on/off times & keep the hot water always hot.
Maybe i have wired up the tank stat wrong..its a landis & gyr model & has terminals 1,2,3 inside not 1,2,C as in the honeywell version..
Any help would be great as i have two women here wanting baths & showers later.

You say you did it to the Honeywell diagram - is it the same as the Y plan in this?
Do you have a multimeter, if so what type/model?
What level of experience do you have in electrical work?
