Controller Features
Push Settings
The ability to transmit user settings from one unit to all other con-
nected units. Select the desired Master Programming settings
on one unit then push the same settings to all other connected
units. After the push settings have completed, you may still make
unique changes to individual units.
Auxiliary Relays
The NXT2 has two auxiliary relays that may be activated based
on cycle, time, or volume.
System 4 - Single Unit
Single Tank configuration Time Clock: No Meter Immediate:
One Meter Delayed: One Meter Remote Signal Start
System 5 (2-8 Units) Parallel Interlock)
All tanks in parallel supplying treated water. Each unit in the
system will have its own flow meter/sensor input. The control
will delay the start of Regeneration if another unit is already in
Regeneration. Once that unit has completed a Regeneration
cycle, and has returned to Service, the unit with the longest
regeneration queue time will begin Regeneration. No more than
one unit will be in Regeneration at time.
System 6 (2-8 Units) Parallel Series
Regeneration
All tanks in parallel supplying treated water. Only #1 control will
monitor flow meter/sensor input. When a regeneration is required
for the system, it will regenerate valve address #1 first, immedi-
ately followed by #2, then #3, then #4 if installed. No more than
one unit will be in Regeneration at a time.
System 7 (2 Units) Alternating Immediate
One tank online supplying treated water, one tank in Standby.
Only #1 control will monitor its flow meter/sensor input.
Regeneration of a unit will begin after the other control has left
Standby and returned to Service. When the Regeneration cycle
is complete, the regenerated unit will enter Standby. Standby on
each tank is controlled by the relay on the NXT2 circuit board.
Activates during selected cycle step
Activates upon selected start time
(Range: 0-91 minutes)
Deactivates upon selected end time
(Range: Start Time plus 1 minute)
Activates when selected volume (gallon)
is reached (Range: 0-99999)
Selected duration in seconds
(Range: 0-9999 seconds)
System 8 (2 Units) Alternating Delayed
Immediate Transfer Delayed Regeneration One tank online sup-
plying treated water, one tank in Standby. Only #1 control will
monitor its flow meter/sensor input. Online unit depletes its vol-
ume. Once this occurs the offline unit comes online. The previ-
ously online unit goes offline and delays its regeneration until the
programmed regeneration time has been reached.
System 9 (2-8 Units) Alternating with
Standby Units
Up to 7 tanks online supplying treated water, one tank
in Standby. Meter/sensor input is required on each tank.
Regeneration of a unit will begin after the other control has left
Standby and returned to Service. When the Regeneration cycle
is complete, the regenerated unit will enter Standby. Standby on
each tank is controlled by the relay on the NXT2 circuit board.
System 14 (2-8 Units) Progressive
Demand Recall
Meter input is required on each tank. Unit #1 will begin In Service
with #2, #3, and #4 (if installed) will begin in Standby. At least
one unit is In Service at all times. When flow rate to the Primary
Service Unit increases to a user specified rate, the next unit in
sequence will move from Standby to Service. As the flow rate
falls below the user specified rate, subsequent tanks will return
to Standby. When the Primary Service Unit regenerates, the
next unit in sequence will become the new Primary Service Unit.
As each units capacity is reached, the controller will initiate a
Regeneration of that unit. Depending on the number of units in
the system and flow rate demand, the regenerated unit will then
be placed either into Standby or Service. Only one unit will be in
Regeneration at a time.
