    Can anyone tell me which terminals to connect which wires to on a Danfoss TP7000M (230v) please? I've been puzzling over it for several hours!

    I've attached wiring diagrams for the above, and for the Danfoss RMT230 which I am replacing. The RMT230 was wired as follows:

    Red wire to 1 (COM)
    Yellow wire to 2 (ON)
    Blue wire to 4 (N)

    (also have an earth wire, which was just shielded and tucked away unattached to any terminal - presume I leave it like this?)

    Thanks for any help.

    Thanks. Do you mean connect the red wire to L and connect a small piece of wire from L to 1? I did try doing this earlier (and it worked!) but I was convinced it was dodgy - as there's barely enough room to squeeze two wires into the L terminal, so much so that I was worried that one would pull out!

    yes

    as long as the two wires are both fully in the terminal when you screw it down it should be fine, if in doubt give them a tug to check.
