Used in good condition Jandy TruClear Power Pack Controller. When salt cell blade set went bad, replaced the system with Pentair. Screen is still clear enough for all the letters to be easily legible and make operation a snap. Hazy displays on used power packs such as this one are the most common problem owners experience when these units age due to excess exposure to direct sunlight. If the displays haven’t fogged up yet, it’s a good sign that their installation orientation luckily preserved them. The only drawback to this unit is the house painters went ahead and painted all the pool equipment to match the exterior walls in an attempt to make it all disappear. It does not affect the performance of the unit.
