Hardness

  • Set the local hardness value in Grains Per Gallon (GPG)

  • For every 1.0 mg/L or PPM of iron+manganese, add 3 GPG to the hardness value

Regen days:

  • sets the maximum number of days between regenerations
  • Default values for Aquatell softeners as follows:
    • Wellmaster = 7 days
    • All others - 10 days
  • These values should not be adjusted without consulting Aquatell or resin damage may result

Regen time:

  • the time of day that regeneration occurs
  • default value is 2:00am

  • during the regeneration, water can be used, but it will not be softened
