Variable Reserve Function
The 700 Series metered-demand volumetric controllers (760 and 760C) are
designed to have a variable reserve feature. This feature automatically
adjusts the reserve to the end-user’s water usage schedule.
A variable reserve saves salt and water by only regenerating when absolutely
necessary, and ensures enough soft water for typical
high-water usage days.
Each day of regeneration the controller reviews the last four weeks of water
usage for the same day of the week to determine if the remaining capacity is
adequate for the next day of the week. If the remaining capacity is not
adequate, it will initiate an automatic regeneration.
