Step 9S –
Select the pounds for the fifth cycle using  or . For valve types 1.5 and 2.0, "oFF" is also
available.
NOTE: if Step 2CS is set to 2.0 or Step 7CS is set to MIN, Fill will be in minutes.
Press NEXT to go to Step 10S. Press REGEN to return to previous step.
Step 10S –
Set System Capacity using  or . The System Capacity setting should be based on the
volume of resin and LBS of salt fill set in Step 9S. Press NEXT to go to Step 11S. Press REGEN to
return to previous step.
Step 11S – Set Volume Capacity using  or . If value is set to:
• "AUTO" capacity will be automatically calculated and reserve capacity will be automatically estimated;
• "oFF" regeneration will be triggered solely by the day override setting (see Installer Display/Settings
Step 4I);
• a number, regeneration will be triggered by the value specified (in Gallons).
If "oFF" or a volume is used, the hardness display will not be allowed to be set in Installer Display
Settings Step 2I. See Setting Options Table for more detail. Press NEXT to go to Step 12S. Press
REGEN to return to previous step.
Step 12S –
Set Regeneration Time Options using  or . If value is set to:
• "NORMAL" means regeneration will occur at the preset time;
• "on 0" means regeneration will occur immediately when the volume capacity reaches 0 (zero); or
• "NORMAL + on 0" means regeneration will occur at one of the following:
— the preset time when the volume capacity falls below the reserve or the specified number of days
between regenerations is reached whichever comes first; or
— immediately after 10 minutes of no water usage when the volume capacity reaches 0 (zero).
"NORMAL" is the default if Step 5CS is set to ALT A or ALT B, and "NORMAL + on 0" is not
available.
"on 0" is the default if Step 2CS is set to 1.0 , and "NORMAL + on 0" is not available.
This step will not appear if Step 11S is set to oFF or Step 5CS is set to "SYS".
See Setting Options Table for more detail. Press NEXT to go to Step 13S. Press REGEN to return to
previous step.
• Gallons Softening Regen on: Relay activates after a set number of gallons have been used while in
service, or during regeneration, and then deactivates after the meter stops registering flow and the set
time period has expired.
• ERROR: Relay closes whenever the valve enters error mode, and immediately deactivates when error
mode is exited. If set to ERROR, Steps 14S and 15S will not be shown.
• Off: If set to Off, Steps 14S and 15S will not be shown.
Press NEXT to go to Step 14S. Press REGEN to return to previous step.
Step 13S –
Set Relay Operation using  or . The choices are:
• Time on: Relay activates after a set time at the beginning of a regen-
eration and then deactivates after a set period of time. The start of
regeneration is defined as the first backwash cycle or Dn brine cycle,
whichever comes first.
• Gallons Softening on: Relay activates after a set number of gallons
have been used while in service and then deactivates after the meter
stops registering flow and the set time period has expired.
