As far as I know, no online dealer programs the control valve to meet the need of each of their customers. I didn't do the programing but I emailed specific data and detailed personalized instructions to every customer. Most if not all online dealers have the equipment shipped from their supplier's location, it's drop shipping, and the suppliers do not change the programing from the manufacturers' default settings. I've never had a supplier do any programming, even as a local dealer. The dealer or installer is responsible to do the programing. From my experience many plumbers have their plumbing house do the programing and many well drillers do the same and it is generic, not specific to the customer's water or such, just based on the K of capacity they use for various sized softeners.
