chapinSC Posted January 6, 2019 Report Share Posted January 6, 2019 Our system was installed in 2009; Jandy Aquarite 20 with a T5 salt cell, and RS4 controller. This summer it appeared our salt cell needed to be replaced (system indicated generating, but clearly salt wasn't being produced). I purchased a generic replacement with excellent reviews, a Platinum Edition PEC-HW-T5 which was supposed to be a direct T-5 replacement. We knew from researching that depending on the firmware revision, the replacement cell might not work, and it didn't. However, the company who supplied the cell is no longer in business, so we couldn't return it or work with them on a firmware upgrade. My unit displays "r 1.4", so I assume that's the revision level. Has anyone done this upgrade or know precisely which part I need? Quote Link to comment Share on other sites More sharing options...
