It could be the Fleck 4200 with the SE control as WaterRight used that one first then moved to the Clack.
Either way Gary is correct, all you did was shorten the back wash time , this time around.
It would depend on how much time was left when you pushed the "next" if you where only 1 or 2 minutes in ... then another cycle would be good, if you only had a couple of minutes left when you pushed it .. then no worries.
