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.
An integrated spa control system comprising:
A low maintenance spa control system that eliminates the need for mechanical flow or pressure monitoring devices by employing a temperature sensor thermally coupled to the spa's main body of water, another temperature sensor thermally coupled to the spa's heater, logic means connected to said sensors, and power switching means connected to said logic means to activate said heater only when said temperature sensors indicate that the temperatures at their respective locations are within a prescribed difference of each other.
A low maintenance spa control system that evaluates the performance of certain components in a spa each time said components are activated by measuring operational parameters of said components.
A low maintenance spa control system that uses LEDs on a user interface to indicate the operational status of components of the spa.
