Bathing unit system controller having abnormal operational condition identification capabilities

A controller for identifying an abnormal operational condition in a bathing unit system that includes a power source and a set of bathing unit components. The controller comprises a power control device (33) and a processing module (40). The power control device (33) is capable of acquiring a first state and a second state. In the first state, said power control device enables the power source to supply power to the set of bathing unit components, and in the second state, said power control device prevents the power source from supplying power to the set of bathing unit components. The processing module (40) is operative for detecting an abnormal operational condition associated with the bathing unit system, and more particularly with the controller itself. Upon detection of an abnormal operational condition associated with the controller, the processing module causes the power control device to acquire the second state.
