Timer Operation
Set Time of Day
When the timer is In Service, push either the Set Up or Set Down button once to adjust the Time of Day by
one digit. Push and hold to adjust by several digits.
Manually Initiating a Regeneration
1. When timer is In Service, press the Extra Cycle button for 5 seconds to force a manual regeneration.
2. The timer reaches Regeneration Cycle Step #1.
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
Timer Operation During Regeneration
In the Regeneration Cycle step display, the timer shows the current regeneration step number the valve is
advancing to, or has reached, and the time remaining in that step. The step number that displays flashes until
the valve completes driving to this regeneration step position. Once all regeneration steps are complete the
timer returns to In Service and resumes normal operation.
Example:
Start a Regeneration Tonight
With metered delayed timers, press the Extra Cycle button momentarily. The In Service indicator dot flashes
and starts a Regeneration tonight at the programmed Regeneration Time.
Day Regeneration Timer
During normal operation the Time of Day display is visible at all times. The timer operates normally until the
number of days since the last regeneration reaches the Regeneration Day Override setting. Once this occurs,
a regeneration cycle is initiated at the preset Regeneration Time.
Flow Meter Equipped Timer
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3).
— As treated water is used, the Volume Remaining display counts down from the calculated system
capacity to zero or (----). When this occurs a Regeneration Cycle begins or delays to the set
Regeneration Time.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
Less than 10 Minutes Remaining in Regen Step #1
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.

3200NT Timer

Timer Operation
Immediate Regeneration Timer with Regeneration Day Override Set
When the valve reaches the set Days Since Regeneration Override value, a Regeneration Cycle initiates
immediately. This occurs even if the Volume Remaining display has not reached zero.
Delayed Regeneration Timer with Regeneration Day Override Set
When the timer reaches the set Days Since Regeneration Override value a Regeneration Cycle initiates at
the preset Regeneration Time. This occurs even if the Volume Remaining display has not reached zero.
Timer Operation During Programming
The timer only enters the Program Mode with the timer In Service. While in the Program Mode the timer
continues to operate normally monitoring water usage and keeping all displays up to date. Timer programming
is stored in memory permanently. There is no need for battery backup power.
Timer Operation During A Power Failure
During a power failure all timer displays and programming are stored for use upon power re-application. The
timer retains all values, without loss. The timer is fully inoperative and any calls for regeneration are delayed.
The timer, upon power re-application, resumes normal operation from the point that it was interrupted.
NOTE: An inaccurate Time of Day display may indicate a power outage.
Remote Lockout
The timer does not allow the unit/system to go into Regeneration until the Regeneration Lockout Input signal
to the unit/system is cleared. This requires a contact closure to activate. The recommended gauge wire is 20
with a maximum length of 500 feet. See P4 remote inputs in the wiring diagrams on
pages 16 - 20 .
Remote Signal Start Regeneration
The control valve monitors treated water other than a flow meter. When timer receives a contact closure for the
programmed amount of time, regeneration begins. The recommended gauge wire is 20 with a maximum length
of 500 feet. See P4 remote inputs in the wiring diagrams on
pages 16 - 20 .
Day Override Feature
If the Day Override option is turned on and the valve reaches the set Regeneration Day Override value without
the water meter initiating a Regeneration Cycle, a Regeneration Cycle queues. This occurs regardless of the
remaining volume available.
WARNING
Transformer must be grounded and ground wire must be
terminated to the back plate where grounding label is
located before installation. See instructions for
Installing
and Grounding the Transformer, page 21
.

System Operations
System 4
Time Clock (1 Valve)
During normal operation the Time of Day display may be viewed at all times. The control operates normally
until the number of days since the last regeneration reaches the Regeneration Day Override setting. Once
this occurs, a Regeneration Cycle initiates at the preset Regeneration Time.
Meter Delayed (1 Valve)
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3).
— As treated water is used, the Volume Remaining display counts down from the calculated system
capacity.
— The system monitors the volume of water used. When the system calculates that there is not a sufficient
capacity for the next day’s operation, a regeneration cycle is initiated at the preset regeneration time.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
Meter Immediate (1 Valve)
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3).
— As treated water is used, the Volume Remaining display counts down from the calculated system
capacity to zero or (----). When this occurs a Regeneration Cycle is started.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
System 5
Interlock (2 – 4 Valves)
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3).
— As treated water is used, the Volume Remaining display counts down from the calculated system
capacity to zero or (----). When this occurs a Regeneration Cycle queues.
— If no other valve is in Regeneration the valve sends a lock command and starts a Regeneration Cycle.
— If another valve is in Regeneration (i.e. the system is already locked) the valve remains In Service with
Regeneration queued until other valves complete Regeneration. Then the system locks and
Regeneration begins.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
System 6
Series (2 – 4 Valves)
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3). The Volume Remaining is the total volume for all units in the system.
— As treated water is used, the Volume Remaining display counts down from the calculated system
capacity to zero or (----). When this occurs a Regeneration Cycle queues.
— If no other valve is in regeneration the lead valve sends a lock command and starts a Regeneration
Cycle.
— When the LEAd valve completes regeneration cycle the remaining valve(s) in the system regenerate
sequentially until all valves regenerate.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
— LAg valve volume remaining is updated every 5 seconds from the LEAd valve.
— A manually forced regeneration (EC key) can only be done on the LEAd valve and only if the system is not
in Regeneration.

System Operations
System 7
Alternating (2 Valves)
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3). The Volume Remaining is for the individual unit.
— As treated water is used, the Volume Remaining display counts down from the calculated capacity to zero
or (----). When this occurs a Regeneration Cycle queues.
— The valve requiring Regeneration sends a lock command to the standby valve. The standby valve goes to
In Service and exhausted valve starts a Regeneration Cycle.
— If a valve is in Regeneration and the other valve exhausts its volume remaining, then the exhausted valve
remains In Service with Regeneration queued until the other valve goes into standby. The exhausted
valve goes into standby after completing Regeneration.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
System 9
Alternating (2 – 4 Valves)
During normal operation the Time of Day display alternates with the Volume Remaining display
(gallons or m3). The Volume Remaining is for the individual unit.
— As treated water is used, the Volume Remaining display counts down from the calculated capacity to zero
or (----). When this occurs a Regeneration Cycle queues.
— The valve requiring Regeneration sends a lock command to the standby valve. The standby valve goes to
In Service and exhausted valve starts a Regeneration Cycle.
— If a valve is in Regeneration and another valve exhausts its volume remaining, then the exhausted valve
remains In Service with Regeneration queued until the other valve goes into standby. The exhausted
valve goes into standby after completing Regeneration.
— All units remain In Service except those in standby or Regeneration.
— Water flow through the valve is indicated by the Flow Dot that flashes in a direct relationship to flow rate.
Important System Operations Tips
❑When programming multi-unit systems, program LAg units first and then LEAd unit. This eliminates or
minimizes lower drive movement due to system type changes and errors.
❑When changing a valve from one system type to another system type, perform a Master Reset first.
❑System 6, 7 and 9 valves coming out of program mode or on power-up calculate their volume (display = CALc)
and then wait for a good communication signal.
— When a good communication signal is received, the system resume normal operations.
— If the system does not receive a good communication signal, CALc displays and the system goes into a
wait. Press the EC key to force the system out of the wait and resume normal operation. A communication
error may appear after one minute.
❑The System 4, 5 and 6 LEAd valve drive sequence going into Regeneration is:
— The lower drive moves to off-line and the upper drive moves to first Regeneration position.
❑All system 7 and 9 valves:
— The off-line valve moves to online, the valve requiring Regeneration moves its lower drive to off-line and
then the upper drive moves to first Regeneration position.
❑Reserve capacity–System 4Fd only. After power-up or Master Reset, the reserve is set by using the safety
factor. Reserve is limited to a range of 0% - 50% of the unit capacity.
❑System 6 and 7, LEAd units only, respond to remote lock and chemical pump. Also chemical pump is available
only if the auxiliary relay in regeneration is not used [AroF]
