    Hi Folks. I purchased a Siemens RWB27 digital timer for my central heating. I'm replacing an old apt timer switch.
    Problem I seem to have is that it's wired L1 black
    L2 Brown L3 blue.
    I'm changing it because I can't get power to the dial rotator and so won't work on timer.
    Any help would be appreciated
    I just need to know how to wire up the new one.
    I tried it and wired it
    live - brown
    Neutral- blue
    L4 - black.
    Timer work but heating won't go on

    Tks

    Hi,

    From the manual if you are switching 240v then you need to link L to T2. That way you get an output on T4 which is your black wire.
