1. A control system for a bathing installation which includes one or more electrically powered devices associated with operation of the bathing installation, a ground fault circuit interrupter (GFCI), and a line voltage service connected through the GFCI to the bathing installation to power said one or more electrically powered devices, the GFCI adapted to interrupt the service from connection to the bathing installation upon detection of a ground fault, the control system comprising:

  • an electronic controller system operatively connected to the one or more electrically powered devices through respective switch devices for controlling the operation of said one or more devices, said switch devices separate and distinct from the GFCI;

    a trip circuit for inducing a ground fault and tripping the GFCI in response to a trip signal, thereby disabling application of electrical power to the bathing installation, including the one or more electrically powered devices and the electronic controller system;

    an electronic circuit responsive to a non-ground fault condition for generating said trip signal, said non-ground fault condition exclusive of a single high water temperature sensor value or a manually-activated switch.
