1. A programmable flow control valve unit for directing the flow of a fluid, said valve unit including a valve assembly operably connected to an electronic assembly, wherein:

  • a. said electronic assembly includes a sequence type control with a programmable memory means operably connected to a means for accepting cycle selections by a user of said programmable flow control valve unit;

    b. said sequence type control includes a selected program for activating said electronic assembly and thereby operate said valve assembly;

    c. said selected program includes at least one discrete program advancing operation;

    d. said discrete program advancing operation is dependent, at least in part, upon said cycle selections;

    e. said electronic assembly further includes a copying means for duplicating said discrete program advancing operation to permit said selected program to have easily duplicated parts;

    f. said electronic assembly further includes a display means operably interconnected with said electronic assembly for providing an indication of instructions given to said programmable flow control valve unit;

    g. said electronic assembly further includes a clock means operably interconnected with said electronic assembly for timing said operations; and

    h. said electronic assembly further includes a control logic means operable during a programmable mode operably connected to said electronic assembly in order to enable the electronic assembly to function;

    i. said sequence-type control is a push button assembly operably connected to said discrete program advancing operation for setting a set of five modes including a clock mode, a program mode, an automatic mode, a manual mode, and a repeat mode;

    j. an enter means is operably connected for loading each of said five modes within said discrete program advancing operation;

    k. said clock mode provides a day readout and a time of day readout within said display means; and

    l. said display means provides a program readout for said discrete program advancing operation and a clock mode readout for said clock mode at the same time.
