2. The timer advances to Regeneration Cycle Step #1, and
begins programmed time count down.
3. Press the Extra Cycle button once to advance valve to

A manually initiated or queued regeneration can
NOTE:
be cleared by pressing the Extra Cycle button for
less than 5 seconds. A system queued regeneration
can only be cleared by stepping through a manual
regeneration. If regeneration occurs for any reason
prior to the delayed regeneration time, the manual
regeneration request shall be cleared. Pressing the
Extra Cycle button while in regeneration will cause the
upper drive to advance to the next step immediately.
Queued Regeneration (RGQ)
From the display screen, while the unit is in service, hold down
the Extra Cycle button until "RGQ" displays. The valve will
regenerate when the set regeneration time has been reached.
Timer Operation During Regeneration
In the main display screen, the timer shows the current
regeneration cycle and the time for that step. The green LED
light will display when the unit is in regeneration. Once all
regeneration steps are complete, the timer returns to in service,
displays a blue LED light, and resumes normal operation.
Timer Operation During Programming
The timer enters program mode (unit must be in service).
While in the program mode the timer continues to operate
normally, monitoring water usage. Timer programming is
stored in memory permanently upon a normal exit from
programming mode.
Timer Operation During A Power Failure
All program settings are stored in permanent memory.
Current valve position, cycle step time elapsed, and time of day
are stored during a power failure, and will be restored upon
power re-application. Time is kept during a power failure, and
time of day is adjusted upon power up (as long as power is
restored within 12 hours).
The time of day on the main display screen will flash
NOTE:
for 5 minutes when there has been a power outage.
The flashing of the time of day can be stopped by
pressing any button on the display.
Regeneration Day Override Feature
If the Day Override option is turned on and the valve reaches
the set Regeneration Day Override value, the Regeneration
Cycle starts at the programmed regeneration time.
Flow Meter Equipped Timer
As treated water is used, the Volume Remaining display
counts down from the calculated system capacity, less the
reserve volume. Once capacity reaches zero or reserve, if the
immediate system the unit will regenerate immediately. If it
is a Fixed, Variable, or Weekly reserve, the unit will queue a
regeneration (RGQ) and count down Reserve Volume until the
set regeneration time.
Reserve Volume is only available in a RGQ system.
