Abstract

A controller suitable for identifying an abnormal operational condition in a bathing system is provided. The controller includes a memory unit adapted for storing measurements indicative of electrical currents drawn by the bathing system under normal operating conditions, each measurement being indicative of the electrical current being drawn by a respective bathing unit component in the bathing system. The controller also includes a processing unit for modifying the measurements stored in the memory unit and for detecting an abnormal operational condition associated with the bathing system at least in part on the basis of measurements stored on the memory unit.
