1. A controller suitable for identifying an abnormal operational condition in a bathing system, the bathing system including a set of bathing unit components, each bathing unit component being adapted for acquiring an actuated state and a non-actuated state, the controller being suitable for establishing a connection with a power source through a ground fault circuit interrupter (GFCI), said controller comprising:

  • a. a memory unit adapted for storing measurements indicative of electrical currents drawn by the bathing system under normal operating conditions, at least some measurements being indicative of electrical currents being drawn by respective bathing unit components when in the actuated state;

    b. a processing unit in communication with said memory unit adapted for;

    i. deriving at least one expected current measurement at least in part based on;

    1. desired state information associated to the bathing unit components in said set of bathing unit components; and

    2. the measurements stored on the memory unit;

    ii. obtaining an actual measurement of a current drawn by the bathing system;

    iii. detecting an abnormal operational condition associated with the bathing system at least in part based on the at least one expected current measurement and on the actual current measurement;

    iv. in response to detection of an abnormal operational condition associated with the bathing system in part based on the at least one expected current measurement and on the actual current measurement, inducing a current leakage to ground such as to cause the ground fault circuit interrupter (GFCI) to trip.
