Abstract: A line voltage transformer device for a bathing installation includes a housing structure, with a line voltage electrical power connection including a line voltage wiring cable having an electrical connection at a distal end for connection to a line voltage AC supply outlet adjacent the bathing installation. A voltage transformer circuit is disposed within the housing and connected to the line voltage electrical power connection and is configured to transform AC line voltage electrical power from the line voltage electrical power connection to low voltage AC power at first and second low voltage AC terminals, wherein the low voltage AC power is delivered to the first and second low voltage AC terminals.

Abstract: A line voltage device with an auxiliary power connection for a bathing installation. An exemplary embodiment of the device includes a housing structure, and a primary electrical power connection connected to the housing structure and including a primary wiring cable for connection to a line voltage source. A load system is disposed within or adjacent the housing and configured for powered operation by electrical power from the primary electrical power connection. An auxiliary power connection is provided for electrical connection to a separate bathing installation device to provide power to the separate device. A wiring circuit is disposed within or adjacent the housing structure and electrically couples the primary electrical power connection and the auxiliary power connection so that line voltage power is shared between the load system and the separate bathing installation device.

Abstract: 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.
