This retrofit is for 2014 – 2018 HL NXT models that had the factory-installed remote and dock.
Control Panel is PN – 78191 / 2018 HL wired “touch screen” control panel.
NOTE: For 2019 and newer HL models, the retrofit can ONLY be done with the Limelight 2019 “button” Control Panel PN-77433 IF the spa is operating on a Fresh Water Salt System. It also requires the 2019 LL software. Because the LL “button” control panel operates differently than the HL “touch” screen.
