Commercial System Valve Configurations
System 4 - Single Valves
System 7
Time Clock (1 Valve)
The control regenerates on the days set in Regeneration Day
Override, at the Regeneration Time set in Regeneration Time.
Commercial Water Softeners
Meter Delayed (1 Valve)
The control regenerates on the day the available volume
of treated water drops to less than the reserve volume.
Regeneration starts at the Regeneration Time.
Meter Immediate (1 Valve)
The control regenerates immediately when the available volume
of treated water drops to zero (0).
System 5 (Fleck controls only)
Meter Immediate (Interlock) (2 – 4 Valves)
This is a 2 to 4 unit system, each unit having a meter, and all in
service. Only one unit is allowed in regeneration at a time. A unit
regenerates immediately when the available volume of treated
water drops to zero (0) and no other unit is in regeneration.

System 6
Meter Immediate Series (2 – 4 Valves)
This is a 2 to 4 unit system, all in service, with one meter for the
entire system. When the entire system volume of treated water
drops to zero (0), it requests the first unit to go into regeneration.
Then, when the first unit is done regenerating, the second
follows, and so on.
Meter Alternating (2 Valves)
This is a 2 unit system, with only one unit having a meter and
only one unit in service. When the volume of treated water
drops to zero (0) in the unit in service, it requests regeneration.
This causes the unit in standby to move to service. Then the
unit requesting regeneration moves to standby and begins
regeneration.
System 9
Meter Alternating (2 – 4 Valves)
This is a 2 or 4 unit system, each unit having a meter, one unit
in standby and all other units in service. Only one unit is allowed
in regeneration at a time. When the volume of treated water
drops to zero (0) in the unit in service, it requests regeneration.
This causes the unit in standby to move to service. Then the
unit requesting regeneration moves to standby and begins
regeneration.
System 14
Meter Progressive (2 – 4 Valves)
This is a 3 or 4 unit system, each unit having a meter, one unit
in service and all other units in standby. As flow rates increase,
units in standby go into service. As flow rates decrease units in
service go back into standby until only one unit is in service. Only
one unit is allowed in regeneration at a time. When the volume of
treated water drops to zero (0) in the unit in service, it requests
regeneration. This causes the unit in standby to move to service.
Then the unit requesting regeneration moves to standby and
begins regeneration.
Note:
1) All Simplex Units to have hard water bypass pistons (White).
2) All Duplex, Triplex and Quads to be NXT2 valves with No Hard Water bypass pistons (Black).
