Selling my system due to moving to a diffrent city

If your talking about the serial number on the Aquacontroller itself, do the self test and it will be displayed. If you need the id. number for aquanotes for the install I think you'll have to track the guy down. When I needed AC tech help I had to fax a photo copy of the original disk and the serial number so they could transfer ownership to me from the previous owner. Maybe if you know the guys name and you can prove you have the original copy maybe Neptune will help you out. They were pretty accomodating to me once they knew my program wasn't a copy.
