Demand Initiated Regeneration & Time Clock Options
The control valve can be set for Demand Initiated Regeneration (DIR) only, Time Clock operation only or DIR and Time
Clock whichever comes first, depending upon what settings are selected for Day Override and Gallon Capacity.

See
Table 3.

See the Installer Display Settings, Step 3I, Filter System Setup Step 6S for explanations of Day Override and Gallon Capacity.
AMI Metered Carbon Filters are programmed for
manual gallons capacity with a 12-Day Override
as default. This
should work for most applications. If different
regeneration settings are required, please see OEM programming section
for setup instructions.

For DIR Filters, set the Gallons Capacity to a specific number. Automatic reserve capacity feature is available for water
softeners only. If a reserve capacity is desired, set the gallon capacity to a value that is lower than the estimated capacity.
The control valve can also be set to regenerate immediately or at the next regeneration time by changing the
Regeneration Time Option. There are three choices for settings:
1. “
NORMAL
” (sometimes referred to as “meter delayed”) means when the gallons capacity reaches zero, it will stay
in service until the next preset regeneration time, at which time regeneration will begin.
2. “
on 0
” means regeneration will occur immediately when the gallons capacity reaches zero.
3. “
NORMAL
” and “
on 0
” means the regeneration will occur at the preset regeneration time unless the gallons
capacity reaches zero. If the gallons capacity reaches zero the regeneration will begin 10 minutes after no water
usage.
AMI Carbon Filters are programmed to
NORMAL
(meter delay) regeneration option. This should work for most
applications. If different
regeneration settings are required, please see OEM programming section for setup instructions.
