10. Variable Reserve (Display Code CR)
Press the Extra Cycle button. Use this display to set the Variable
Reserve. This setting is formulated to adjust the reserve depen-
dant on the previous calendar day’s water usage. During each
regeneration, the reserve will change based on the old reserve
capacity and the previous day’s water usage. This option setting
is identified by “CR” in the upper left corner of the screen.
11. Day Override (Display Code DO)
Press the Extra Cycle button. Use this display to set the Day
Override. This setting specifies the maximum number of days
between regeneration cycles. If the system is set to a timertype
control, the day override setting determines how often the sys-
tem will regenerate. A metered system will regenerate regardless
of usage if the days since last regeneration cycle equal the day
override setting. Setting the day override value to “OFF” disables
this function. This option setting is identified by “DO” in the upper
left corner of the screen. Use the Up and Down buttons to adjust
the value as needed.

12. Regeneration Time
Press the Extra Cycle button. Use this display to set the
Regeneration Time. This setting specifies the time of day the
control will initiate a delayed, manually queued, or day override
regeneration. This option setting is identified by “RT” in the upper
left corner of the screen. Use the Up and Down buttons to adjust
the value as needed.
13. Regeneration Cycle Step Times
Press the Extra Cycle button. Use this display to set the
Regeneration Cycle Step Times. The different regeneration cycles
are listed in sequence based on the valve type selected for the

If the system has been configured with the “Other” valve type,
the regeneration cycles will be identified as C1, C2, ..., C20.
Cycle steps can be programmed in any order using the Up or
Down buttons with the following selections. Up to 20 individual
cycles can be set. Time for each cycle can be set from 0 to 199
minutes. Setting a cycle step time to 0 will cause the control to
skip that step during regeneration, but keeps the following steps
available. Use the Up and Down buttons to adjust the value as
needed. Press the Extra Cycle button to accept the current
setting and move to the next parameter. Program the last cycle
step as LC which forces the valve back to the service position.

14. Day of Week Settings
Press the Extra Cycle button. Use this display to set the regen-
eration schedule for a system configured as Day of Week control.
The different days of the week are identified as D1, D2, D3, D4,
D5, D6, and D7 in the upper left corner of the display. Set the
value to “ON” to schedule a regeneration or “OFF” to skip
regeneration for each day. Use the Up and Down buttons to
adjust the setting as needed. Press the Extra Cycle button to
accept the setting and move to the next day. Note that the
control requires at least one day to be set to “ON” If all 7 days
are set to “Off”, the unit will return to Day 1 until one or more
days are set to “ON”.
