    Never played with these before...
    Now I have to replace one in the electric furnace and cannot find a site that lists numberings.
    Anyone with knowledge about these please ?

    It looks like:
    ----> http://ww2.justanswer.com/uploads/BM/bmw850calypsored/2013-02-17_054529_sequenceside.jpg
    And numbers shown are:
    H10-20 C30-70 B12565-5S
    Which should mean 'heats in 10 to 20 seconds; cools in 30 to 70 seconds' plus something.
    And more numbers : 15S2 H24V 309837 A0537 Which are relevant ?

    Seems to have a PTC element on 24VAC that pushes a rod to make contacts. It powers heater elements in intervals to avoid current inrush at startup.

    Your photo is a stacked sequencer. Klixon Brand IIRC. Very common. I probably have 3 or 4 in stock.
    Your interpretation of the numbers is correct.
