Manually Initiating a Regeneration
1. When controller is In Service or Standby, press and hold the
Extra Cycle button on the main screen.
2. The controller advances to Regeneration Cycle Step #1, and
begins programmed time count down.
3. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #2 (if active).
4. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #3 (if active).
5. Press the Extra Cycle button once to advance valve to

back to In Service.
NOTE: A manually initiated or queued regeneration can be
cleared by pressing and holding the Back button. A sys-
tem 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.
Controller Operation During Regeneration
In the Regeneration Cycle step display, the controller shows the
current regeneration cycle name the valve is in, or has reached,
and the time remaining in that step. Once all regeneration steps
are complete, the controller returns to In Service and resumes
normal operation.
Press the Extra Cycle button during a system queued
Regeneration Cycle to immediately advance the valve
to the next cycle step position and resume normal
step timing.
Controller Operation During Programming
The controller enters the Program Mode in Standby or Service
Mode as long as it is not in regeneration. While in the Program
Mode, the controller continues to operate normally monitoring
water usage. Controller programming is stored in memory
permanently.
Controller 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 all
stored during a power failure, and will be restored when power
is re-applied. 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).
NOTE: The time of day on the main display screen will
flash 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.
Flow Meter Equipped Controller
As treated water is used, the Volume Remaining display counts
down from the calculated system capacity to zero. When zero
is reached, a Regeneration Cycle begins if no other units are
in regeneration.
