Programming a Meter Immediate Regenerated System
1. Feed water hardness (Display Code H).
The feed water hardness setting displays only if the system is set to operate as a Meter Immediate or Meter
Delayed system type.
— Press the Set Up and Set Down buttons to set the amount of feed water hardness (grains/gallon or
degrees). The system automatically calculates treated water capacity based on the feed water hardness
and the system capacity preset in the Master Programming mode.
Example:
Range: 4 – 199 US and Metric
— To program 9 grains / gallon (US) or 9 degrees (Metric) [H – 9]
— Press the Set Up and Set Down buttons to adjust this value.
— Press the Extra Cycle button once to Exit Setup Programming Mode or press and hold the Up and Down
buttons simultaneously for five (5) seconds to enter the Extended Setup Programming Mode.

programmed is displayed in the first digit of the display. Each display is used to set the duration time in minutes
of that specific step in the Regeneration cycle.
Example:

Cycle Step dF dFFF FLtr
1 10 = Backwash 12 = Refill 10 = Backwash
2 60 = Brine Draw 60 = Brine Making 10 = Rapid Rinse
3 5 = 2nd Backwash 10 = Backwash
4 10 = Rapid Rinse 60 = Brine Draw
5 12 = Refill 5 = 2nd Backwash
