Low maintenance spa control system
First Claim
1. An integrated spa control system comprising:
- a spa pack housing enclosure including one or more function module cutouts and a cover;
a power distribution circuit board assembly coupled to a source of electrical power, said circuit board assembly disposed in said spa pack housing enclosure and including high voltage and high current circuit parts including one or more high voltage switching devices;
one or more electrical loads coupled to said power distribution circuit board assembly;
one or more removable function means connected to said power distribution circuit board assembly by connector means, said one or more removable function means including a removable function module including a module housing, a function circuit board assembly disposed in said module housing, said function module configured for removal and replacement through one of said function module cutouts without removal of the spa pack housing cover; and
one or more sensor means coupled directly or indirectly to one or more of said function means;
where said one or more function means includes programming means and is configured to analyze signals from applicable ones of said one or more sensor means and to energize said loads according to said signals and said programming means within said function means.

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.
