I have been going by the salt readings on my Jandy remote and just noticed that there is a hand written note on the pool control panel that says "Calibrated +700", from the prior owner / maintenance company. I would like to rest this to factory settings as I don't trust the company they used. I read the Jandy SWG manual and it shows how to calibrate it, but not how to reset a prior calibration. Additionally, do I have to remove the screws and get behind the Aqualink pool control panel to get to the SWG controls ?
