Replacement parts for spas/hot tubs built by Jacuzzi Whirlpool Bath 1994-2002.
Jacuzzi Whirlpool Bath migrated from a simple mechanical spa controler to fully electronic in 1994-95. What this means that earlier then 1994 the control box underneath would be larger relays and gangs of wires and mechanical components. Industry wide hot tubs switch to electronic pcboards and has so since then.
This enabled Jacuzzi to built into the system specific setups for that particular model. Example would be jets would automatically turn off after a period of time. Prior to that the jets would stay on forever or until the motor failed. Another improvement are digital readouts and accurate setting of temperature. A nice feature is automatic filtering that placed less demand on the homeowner; the spa almost took care of itself.
