Timer Operation
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).
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.
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 the reserve volume, the system will regenerate based on the set
regeneration time. If set for an Immediate system, the unit will regenerate immediately once it reaches zero
capacity. 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.
NOTE: Reserve Volume is only available in a RGQ system.
