INSTALLATION
Water Pressure
A minimum of 20 pounds (1.4 bar) of water pressure is required
for regeneration valve to operate effectively.
Electrical Facilities
An uninterrupted alternating current (A/C) supply is required.
Note: Other voltages are available. Please make sure your
voltage supply is compatible with your unit before installation.
Existing Plumbing
Condition of existing plumbing should be free from lime and
iron buildup. Piping that is built up heavily with lime and/or iron
should be replaced. If piping is clogged with iron, a separate
iron lter unit should be installed ahead of the water softener.
Location Of Softener And Drain
The softener should be located close to a drain to prevent air
breaks and back ow.
By-Pass Valves
Always provide for the installation of a by-pass valve if unit is
not equipped with one.
CAUTION
Installation Instructions
1. Place the softener tank where you want to install the unit
2. During cold weather, the installer should warm the valve to

Setting the Time of Day
1. Press and hold the Up or Down button for 2 seconds.
2. Press the Shift button to select the digit you want to modify.
3. Press the Up or Down buttons to adjust the value.
4. Press the Extra Cycle button to return to the normal display
screen, or after a 5 second timeout.
NOTE: The “D” button (Diagnostic) can be pressed to exit
without saving.
Manually Initiating a Regeneration
1. When timer is in service, press the Extra Cycle button for 5
seconds on the main screen.
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
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
Regeneration Cycle Step #4 (if active).
6. Press the Extra Cycle button once to advance valve to
Regeneration Cycle Step #5 (if active).
7. Press the Extra Cycle button once more to advance the
valve back to in service.
NOTE: A queued regeneration can be initiated by
pressing the Extra Cycle button. To clear a queued
regeneration, press the Extra Cycle button again
to cancel. If regeneration occurs for any reason
prior to the delayed regeneration time, the manual
regeneration request shall be cleared.

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
ash for 5 minutes when there has been a power
outage. The ashing 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.
