I have taken the fronts off all the controls but the Lee is still 240v on the orange and the grey cables and when I turn the far right switch on or off this turns the hot water on and off without any controls. Is there a wire I need to move etc?? I have tried it with the MV head from the heating valve and re wired it but it does exactly the same thing so can’t be the head as the Heating head works fine when it’s on the Heating.
