SYSTEM SETUP SCREENS (CONTINUED)
SYSTEM SETUP 4B
SYSTEM SETUP 4A
SYSTEM SETUP 4B – Set Pre-Service Rinse
- Only available on Alternator systems
- Standby units will run through a rinse cycle before coming into service
SYSTEM SETUP 4A - Set fl ow add point
– Only available on Progressive systems
– Sets the fl ow rate which controls the point at which more valves are brought online or
taken offl ine based on the fl ow rate
• Delayed systems will fl ag “lead” units based on “lag” capacity, but will not alternate with
remaining capacity until the next available delayed time.
- Day over ride
• 1 day; 1 unit will regen
• Day triggered regens will run at the time set set for the fi rst regeneration window
Progressive (Demand Recall):
one unit is always online & additional units are added as the
online units exceed the fl ow add point.
• Additional units are brought online when:
- The adder point is exceeded for 30 seconds
- All required units required to cover the fl ow conditions will be brought into service
immediately if the fl ow exceeds 120% of the adder point.
• Units will go offl ine when
- System fl ow reduces to 95% of the set adder point / unit for 1 minute.
• Any unit in a demand recall system will determine the need to regenerate based on:
- Each unit individually reaching 0 capacity
• Immediate systems will regenerate depleted units immediately after current fl ow
conditions allow depleted units offl ine.
• Delayed units will alternate lead units immediately upon exhaustion & regenerate them
at the next available time slot.
- Day Override
• One unit will be regenerated per delayed time slot (i.e. a 4 unit system will need 4
delayed times to regenerate all units / set number of days).
• Day triggered regens will run at the time set in the fi rst regeneration window
- Units cannot regenerate if fl ow demands them to remain online
• Immediate units regen immediately after fl ow allows them offl ine
• Delayed units regen at the next available time slot
• Day units regen at the next time slot
SYSTEM SETUP 5
SYSTEM SETUP 5 - Select bypass control
• Selections allow enabling and timing control of motorized drive
• Selection availability can vary by the type of system
• Custom timing sequences can be confi gured under “Custom Motorized Drive Timing” at
the end of the programming section
Hardwater Bypass
• Only available on single units
• Unit will internally bypass hard water to the service lines while in regeneration
No Hardwater Bypass
• Each unit has isolation to control system operation and will not supply service water
during regeneration
• Drive timing will bring the unit into service during fi ll
