[Jewelry making - Article 00393] - [Orchid] Trouble with Swest controller

    Hello all!  I am really hoping someone can help me with two problems
    I have been having with my Swest Controller for my Neycraft kiln. The
    controller is Model # DTC-617  120v 15amp. The first question is: why
    can't I do more than 6 steps in my burnout cycle?  I start with the
    4step burnout: 

        9999 degrees to 300 for 1 hour
        100 degrees to 350 for 1 hour
        350 degrees to 1350 for 2 hours
        drop 300 degrees to casting temp.

    That's 4 steps, but if I have 5 flasks in the oven with 5 different
    casting temps, I am out of steps. Follow me? So far I seem to be
    limited to 3 temp changes per casting day. 

    The next question is a real problem. When the controller gets to the
    last step, be it 4 or 6 steps, it suddenly shoots up in temperature,
    or sometimes plummets in temperature.  I am asking it to hold at say
    900degrees for 1 hour and all of the sudden the kiln is at 1100
    degrees!  I am not sure what to do!  

    Of course I tried to contact Swest, but they are no longer in
    business. Please help!
