Every night at 2am the softener asks if it has enough capacity remaining to make it thru the next day. If not, it regenerates. The RS is reserve setting. rc says use RC (reserve capacity) in gallons. RS=sf is safety factor in percent.
They do the same thing... define how much reserve.
The display number counts down to zero. If at 2 AM, the display says 3, it waits until the next day to check again. So the number does not include the gallons that are in the reserve.
