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.

TROUBLESHOOTING - TIMER

If an error is detected, an error screen will alternate with the
main display screen every few seconds, and the LED light will

be Red.

During an error condition, the unit continues to monitor the
ow meter and update the remaining capacity. Once an
error condition is corrected, the unit returns to the operating
status it was in prior to the error, and regeneration resumes
according to normal programming. If an error is cleared by
reprogramming the unit in the Master Programming Mode,
the volume remaining may be reset to the full unit capacity
(as though it had just regenerated). If an error is present,
a regeneration can only occur manually by pressing and
holding the Extra Cycle button for 5 seconds. If the unit was
in regeneration when the error occurred, it will complete the
regeneration cycle and go into service.

When the problem is corrected, and the error no longer
displays (it may take several seconds for the unit to stop
displaying the error message), the unit will return to normal
operation. The LED light will no longer be Red, and will
turn Green if the unit is regenerating, or Blue if the unit is in
service.

Unplug the unit and examine the powerhead. Verify that all cam switches are
connected to the circuit board and functioning properly. Verify that the motor
and drive train components are in good condition and assembled properly.
Check the valve and verify that the piston travels freely. Replace/reassemble
the various components as necessary.

Plug the unit back in and observe its behavior. The unit should cycle to
the next valve position and stop. If the error re-occurs, unplug the unit and
contact technical support.

Unplug the unit and examine the powerhead. Verify that all cam switches
are connected to the circuit board and functioning properly. Enter Master
Programming mode and verify that the valve type and system type are set
correctly with regard to the unit itself.

Step the unit through a manual regeneration and verify that it functions

Perform a Manual Regeneration to reset the error code.

If the system is metered, verify that it is measuring ow by running service

measure ow, verify that the meter cable is connected properly and that the
meter is functioning properly.

Enter a Master Programming Mode and verify that the unit is congured
properly. As appropriate for the valve conguration, check that the correct
system capacity has been selected, that the day override is set properly,
and that meter is identied correctly. If the unit is congured as a Day-of­Week system, verify that at least one day is set ON. Correct the settings as
necessary.

Problem: Softener delivers hard water

Reason: Reserve capacity has been exceeded.

Correction: Check salt dosage requirements and reset program
