1. A method for trouble-shooting an irrigation system having a source of water, a plurality of independent irrigation branches, valve means connecting said branches to said source of water, and a completely self-contained controller means having a water supply control portion connected for control of the flow of water to said branches from said source of water and having a branch selection control portion connected to said valve means and formed to enable selection of any one of said branches for the flow of water therein, comprising the steps of:

  • (a) providing a radio receiver means formed and tuned for receipt of both a water supply signal and a differing station selection signal, said receiver including actuation means formed with a first solenoid switch electrically connected for triggering by said water supply signal to actuate said water supply control portion of said controller means, said actuation means further being formed with a second solenoid switch electrically connected for triggering by said differing station select signal to actuate said branch selection control portion of said controller means;

    (b) without modifying the electrical circuitry of said self-contained controller means, electrically connecting a first output connections of said radio receiver means to said water supply control of said controller means for actuation thereof;

    (c) without modifying the electrical circuitry of said self-contained controller means, electrically connecting a second output connections of said radio receiver to said branch selection control portion for actuation thereof;

    (d) carrying a radio transmitter formed for selective transmission of said water supply signal and said station selection signal to an area remote of said controller means and proximate a suspected source of trouble in said irrigation system;

    (e) while proximate the suspected source of trouble, transmitting a station select signal to said receiver means;

    (f) while proximate the suspected source of trouble, transmitting a water supply signal to said receiver means;

    (g) terminating said water supply signal prior to attempting to repair said irrigation system; and

    (h) thereafter transmitting a second water supply signal to said receiver means to enable testing of the repaired irrigation system.
