1. An apparatus for controlling a temperature device, comprising:

  • heat mode select switch means for placing said apparatus in a heat mode of operation from which one of three selectable states can be entered;

    automatic state select switch means for placing said apparatus in an automatic operation state when said apparatus is placed in said heat mode;

    isothermal state select switch means for placing said apparatus in an isothermal operation state when said apparatus is placed in said heat mode;

    manual state select switch means for placing said apparatus in a manual operation state when said apparatus is placed in said heat mode;

    information entry switch means for providing manually selectable numerical data to said apparatus;

    temperature information select switch means for directing said apparatus to receive manually selectable temperature information from said information entry switch means;

    time information select switch means for directing said apparatus to receive manually selectable time information from said information entry switch means;

    rate information select switch means for directing said apparatus to receive manually selectable rate information from said information entry switch means;

    casing data select switch means for instructing said apparatus to utilize predetermined casing temperature and casing time parameters stored in a memory of said apparatus;

    liner data select switch means for instructing said apparatus to utilize predetermined liner temperature and liner time parameters stored said memory;

    squeeze data select switch means for directing said apparatus to utilize predetermined squeeze temperature ans squeeze time parameters stored said memory;

    means, responsive to the sequential actuation of said heat mode select switch means, said automatic state select switch means, one of said casing data select switch means, liner data select switch means, or squeeze data select switch means, said information entry switch means, said rate information select switch means, and said information entry switch means, for controlling the temperature device using the predetermined temperature and time parameters selected by the actuation of one of said casing data select switch means, said liner data select switch means or said squeeze data select switch means;

    means, responsive to the sequential actuation of said heat mode select switch means, said isothermal state select switch means, said temperature information select switch means, and said information entry switch means, for controlling the temperature device to reach a selectable temperature as selected by the actuation of said temperature information select switch means and said information entry switch means;

    means, responsive to the sequential actuation of said heat mode select switch means, said manual state select switch means, one of said casing data select switch means, liner data select switch means, or squeeze data select switch means, said information entry switch means, and either said temperature information select switch means and said information entry switch means or said time information select switch means and said information entry switch means, for controlling the temperature device in an automatic with partial override substate wherein the predetermined temperature and time parameters selected by the actuation of one of said casing data select switch means, said liner data select switch means, or said squeeze data select switch means are overridden by the temperature or time data manually selected by the actuation of one of said temperature information select switch means and said information entry switch means or said time information select switch means and said information entry switch means;

    means, responsive to the sequential actuation of said heat mode select switch means, said manual state select switch means, said temperature information select switch means, said information entry switch means, said time information select switch means and said information entry switch means, for controlling the temperature device to achieve a temperature selected by the actuation of said temperature information select switch means and said information entry switch means in a time selected by the actuation of said time information select switch means and said information entry switch means; and

    means, responsive to the sequential actuation of said heat mode select switch means, said manual state select switch means, said rate information select switch means, said information entry switch means, said temperature information select switch means, and said information entry switch means, for controlling the temperature device to achieve a temperature selected by the actuation of said temperature information select switch means and said information entry switch means at a rate selected by the actuation of said rate information select switch means and said information entry switch means.
