System 4
Time Clock (1 Valve)
The control regenerates on the days set in Regeneration Day Override,
at the Regeneration Time set in Regeneration Time.
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
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.
System 7
Meter Immediate 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 Immediate Alternating (2 – 4 Valves)
This is a 3 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 Immediate Alternating (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. |
