OPERATION
TIMER OPERATION DURING PROGRAMMING
The timer enters the Program Mode in standby or service mode as long as it is not in regeneration. While in the
Program Mode the timer continues to operate normally monitoring water usage. Timer programming is stored in
memory permanently.
TIMER OPERATION DURING A POWER FAILURE
All program settings are stored in permanent memory. Current valve position, cycle step time elapsed, and time of
day are stored during a power failure, and will be restored upon power re-application. Time is kept during a power
failure, and time of day is adjusted upon power up (as long as power is restored within 12 hours).
NOTE:
The time of day on the main display screen will flash for 5 minutes when there has been a power outage.
The flashing of the time of day can be stopped by pressing any button on the display.
REMOTE LOCKOUT
The timer does not allow the unit/system to go into Regeneration until the Regeneration Lockout Input signal to
the unit is cleared. This requires a contact closure to activate the unit. The recommended gauge wire is 16 AWG with
a maximum wire length run of 50 feet.
REGENERATION DAY OVERRIDE FEATURE
If the Day Override option is turned on and the valve reaches the set Regeneration Day Override value, the
Regeneration Cycle starts if no other unit is in Regeneration. If other units are in regeneration, it is added to a
regeneration queue. This occurs regardless of the remaining volume available.
FLOW METER EQUIPPED TIMER
As treated water is used, the Volume Remaining display counts down from the calculated system capacity to zero.
When zero is reached, a Regeneration Cycle begins if no other units are in regeneration.
SYSTEM OPERATION
System 14 (2-8 Units) 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 Stand-
by. At least one unit is In Service at all times. When flow rate to the Primary Service Unit increases to a user speci
-
fied 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 ecomethe 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.
