IMPORTANT PLEASE READ:
The information, specications and illustrations in this manual are based on the latest information available at the time of •
printing. The manufacturer reserves the right to make changes at any time without notice.
This manual is intended as a guide for service of the valve only. System installation requires information from a number of •
suppliers not known at the time of manufacture. This product should be installed by a plumbing professional.
This unit is designed to be installed on potable water systems only.•
This product must be installed in compliance with all state and municipal plumbing and electrical codes. Permits may be •
required at the time of installation.
If daytime operating pressure exceeds 80 psi, nighttime pressures may exceed pressure limits. A pressure reducing valve must •
be installed.
Do not install the unit where temperatures may drop below 32°F (0°C) or above 110°F (43°C). •
Do not place the unit in direct sunlight. Black units will absorb radiant heat increasing internal temperatures. •
Do not strike the valve or any of the components.•
Warranty of this product extends to manufacturing defects. Misapplication of this product may result in failure to properly •
condition water, or damage to product.
A prelter should be used on installations in which free solids are present. •
In some applications local municipalities treat water with Chloramines. High Chloramine levels may damage valve components.•
Correct and constant voltage must be supplied to the control valve to maintain proper function.•

CYCLE 1 00:00:00
BACK WASH
Setting the Time of Day
NOTE: Set Time of Day on the Lead Unit (#1) and the rest of the units in the system will populare with the
Time of Day within 10 seconds.
Press and hold the Up or Down button for 2 seconds. 1.
Press the Shift button to select the digit you want to modify.2.
Press the Up or Down buttons to adjust the value.3.
Press the Extra Cycle button to return to the normal display screen, or after a 5 second timeout.4.
NOTE: The “D” button (Diagnostic) can be pressed to exit without saving.
Manually Initiating a Regeneration
When timer is in service or stand by, press the Extra Cycle button for 5 seconds on the main screen.1.
The timer advances to Regeneration Cycle Step #1, and begins programmed time count down.2.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #2 (if active).3.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #3 (if active).4.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #4 (if active).5.
Press the Extra Cycle button once to advance valve to Regeneration Cycle Step #5 (if active).6.
Press the Extra Cycle button once more to advance the valve back to in service.7.
NOTE: A manually initiated or queued regeneration can 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.
Timer Operation During Regeneration
In the Regeneration Cycle Step display, the timer shows the current regeneration cycle number the valve is on, or
has reached, and the time remaining in that step. Once all regeneration steps are complete the timer returns to in
Service and resumes normal operation.
Example: 12 Minutes Remaining in Cycle 1 (Back Wash)
Press the Extra Cycle button during a Regeneration Cycle to immediately advance the
valve to the next cycle step position and resume normal step timing.
Flow Meter Equipped Timer
During normal operation, the Time of Day screen alternates with the error screen (if errors are present).•
As treated water is used, the Volume Remaining display counts down from the calculated system capacity to •
zero. When this occurs a Regeneration Cycle begins if no other units are in regeneration.

Timer Operation
Timer Operation During Programming
The timer enters the Program Mode in standby or service mode as long as it is not in regeneration. While in the
Program Mode the timer continues to operate normally monitoring water usage. Timer programming is stored in
memory permanently.
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.
Remote Lockout
The timer does not allow the unit/system to go into Regeneration until the Regeneration Lockout Input signal to
the unit is cleared. This requires a contact closure to activate the unit. The recommended gauge wire is 20 with a
maximum length of 500 feet. See P4 remote inputs in the wiring diagrams in the service manual.
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 if no other unit is in Regeneration. If other units are in regeneration, it is added to a
regeneration queue. This occurs regardless of the remaining volume available.

Valve State:
CHG (Change of State)
CHG will be displayed when the lower drive changes from one state to another in dual piston valves.
INI (Initializing)
INI will display on the screen for 30 to 45 seconds when initializing after a power failure reset or programming.
RGQ (Regeneration Queued)
RGQ indicates that the reserve has been entered in a delayed system and regeneration has been queued.
When in the main screen, press the Extra Cycle button to toggle service (SRV) with RGQ.
Service (SRV)
SRV will display when the unit is in service.
LCK (Lock)
Lock will be displayed when the terminal/remote input block P4 on the circuit board is switched to “lock”.
See the “Network/Communication Cables & Connections” section of this manual.
LED Status Lights:
Blue LED:
Illuminates while the unit is in service and no errors exist. The unit will always be in service unless a
regeneration trigger has occurred (green LED light will be displayed).
A blinking blue light indicates the timer is in service, and queued for regeneration.
Green LED:
Illuminates when the unit is in Regeneration mode, unless an error condition exists.
A blinking green light indicates the timer is in standby, and not in regeneration.
Red LED:
Illuminates when there is an error.
Flow Indicator:
A rotating line (appearing as a rotating star shape) will display on the screen when ow is going through the
the meter.

Network/Communication Cables & Connections
Use either a CAT3 or CAT5 Network/Communication cable.
1. Connect the network/communication cable rst before programming.
2. The maximum cable lenth between timers is 100 feet.
3. Connect each unit together from one communication port to the next communication port. It does not
matter which one goes to the next one.
