Time Clock: No Meter
Immediate: One Meter
Delayed: One Meter
Remote Signal Start: No Meter
Single tank configuration.
5
Interlocked
2, 3, or 4
Immediate: All Meters
Remote Signal Start: No Meter
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 longest regeneration queue time will begin
Regeneration. No more than one unit will be in Regeneration at a time.

Series
Regeneration
2, 3, or 4
Immediate: One Meter
Delayed: One Meter
Remote Signal Start: No Meter
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, immediately
followed by #2, then #3, then #4 if installed. No more than one unit
will be in Regeneration at a time.
7
Twin
Alternating
2
Immediate: One Meter
Remote Signal Start: No Meter
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 lower
drive output terminals on the NXT circuit board.
9
Multiple Tank
Alternating
2, 3, or 4
Immediate: All Meters
Remote Signal Start: No Meter
One, two, or three 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 lower
drive output terminals on the NXT circuit board.

Demand
Recall
2, 3, or 4
Immediate: All Meters
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.
