A spa control system designed to reduce maintenance cost by providing modular construction for major control functions, with built-in diagnostic capabilities for isolating defective spa components. Multi-colored LEDs on the spaside panel constantly report the status of each component of the spa as well as the status of the functional modules themselves. Each time a component is activated, measurements of operational parameters, such as load currents, are instantly made and evaluated so that the proper LED color can be presented at the spaside. Since major functions such as audio, LED control, wireless, and spa logic are separated into removable modules, repair of the control system requires less time and less skilled personnel. Other design improvements, such as direct monitoring of heater element temperature and the purging of pumps on an as required-basis, enhance the spa's overall reliability and thus reduce the need for maintenance.

The Space-Time Mapping Analysis (STMA) method and system provides an engineering method and / or system for modeling and / or analyzing and / or designing and / or building and / or operating complex physical processes, components, devices, and phenomena. STMA can be used in a way for modifying and / or improving the design of many different products, components, processes, and devices, for example. Any physical system, whether existing or proposed, which exhibits, for example, unsteady flow phenomena, might be modeled by the STMA. Thus, STMA can be implemented as a part of an engineering system for design improvements and / or modifications and / or evaluations. The STMA system and / or method uses a space-time mapping technique wherein the space and time directions are treated in an equivalent way, such that, rather than solving a three-dimensional unsteady problem by sweeping in the time direction from an initial point in time to a final point in time, the problem is solved as a four-dimensional problem in space-time.
