Main Menu
DISPLAY SETTINGS
UNITS: Select English or Metric.
TIME: Set the current time of day.
REGEN TIME: Set the regeneration time, if using the Delayed Mode.
REGENERATION SETTINGS
Choose the settings best for your household.
TYPE:
High Capacity - Softener will regenerate less often, but will use more salt.
High Efficiency - Softener will regenerate more often using more water, but less salt.
This is the default. This setting meets or exceeds the requirement some states have for
efficiency.
Automatic - Uses the average daily water usage to determine salt usage and
regeneration cycles. Recommended for large households or those with high levels of
water hardness.
MODE:
Demand - Triggers a regeneration as soon as softening capacity is exhausted. This is
the default.
Delayed - Allows regeneration at a specific time (ex. 2 A.M. when less water is typically
being used).
ALARM SETTINGS
LOW SALT: Select On or Off.
LOW TEMPERATURE: Select On or Off.
WATER USAGE: Toggle between On and Off.
