automatically adjusts to water demands and provides continuous conditioned water while providing considerable savings on salt

and water. The 740 has the option for 7 day or up to 99 day regeneration setting. The 760 includes single programming and a 28

day variable reserve feature with the ability to change regeneration time, making it quite efficient and cost effective.
