Confused on best regeneration settings 2092 Isobar 1

[birchlake]

**WaterSoft 24,000 unit (circa 2011) Demand water softener model DS24VP with the 2092 Isobar 1 Control Valve
**My house has well water with 10 grains water hardness. No iron, no manganese. I am in a very pure MN aquifer 320 feet down.
**Salt settings are Pre-Set at the factory for the maximum shown on the capacity chart.
**It's only me in the house, guests are very minimal

I am trying to determine the best setting for automatic regeneration. I've been online and what I am seeing is all over the board so I'm a bit confused!

One site calculated that I could go approximately 2,000 gallons between regens. Another site says that with my minimal usage, I could go to the maximum unit setpoint of 2,400 gallons between regens.. Then I also see other sites which say that I shouldn't go longer than 14 days between regens, another site says I shouldn't go longer than 21 days and yet another says I shouldn't go longer than 28 days!

With many of you guys working on them on a regular basis and if it were your unit with the above specs, what are your recommendations? My concern is that if I set it to a 2,000 gallon regen cycle, this would then put me at around 28 days between regenerations...... is that too long?? Is that enough to keep the softener resin healthy?

Thanks in advance!

I don't know that unit. I would presume you have a 8" x 44" or 9" x 35" inch tank with 0.75 cuft of resin.

Not going over 28 or 30 days should be fine if negligible iron.

Other than that, what settings are available to you? I would enter hardness at 11 for now. I would set it to about 7 pounds of salt use, but 6 or 8 are both reasonable.

At 7lbs/cuft (5.25 lbs) of salt, you should get about 16500 grains of softening.

Instructions are to place thumb firmly on the white dot to hold the outer gear while setting the program wheel. Lift out the "people" dial and rotate it so that the number of people in the family is aligned with the compensated hardness in grains per gallon. The capacity arrow will not be aligned to the gallons of water that will be used between each regeneration as shown on the gallons label located outside the "people" dial. See attached diagram. If preferred, the unit can be set by gallons using this procedure. To calculate gallons, divide the grain capacity of the unity by the compensated hardness level. It is advisable to subtract one day of water usage to provide a reserve.

Salt settings are pre-set at the factory, and yes it is an 8 X 44 tank with 0.75 cubic feet of resin. Sorry for not including those details, I edited my original post to include those specs.

If I set it this way, with a little buffer that gets me to 2,000 gallons between regeneration. Which for me is around 27 days if I use 75 gallons per day as I'm a light user? Too long between regens?

I get less, at least partly because I am applying "high-hardness compensation".

So more like 1552 gallons before taking off the extra day's worth.

I calculate with 60 gallons per day per person, rather than 70, largely because toilets take less water.

Your pictures look very much like the Economizer. So if you look that up, you will probably find something familiar.
