SYSTEM OPERATION IN SERVICE
(SYSTEM 14-DEMAND)
Thesystemoperatesaspartofamulti-tankregeneration
system.Thisexampleappliestoeithera2,3or4tanksystem.
Eachtankinthesystemwillhaveanactiveowmeterinput,
eveninStandby.
ThenumberoftanksInServicedependsontheowrate.
Examples of a Four-Unit System:
1. OneTankisInServiceatalltimes(the"primarytank").

System Operation in Regeneration:

Manually Initiating a Regeneration
1. WhentimerisInServiceorStandBy,presstheExtraCycle
buttononthemainscreenforve(5)secondstoforcea
manualregenerationifanotherunitisnotinRegeneration.

Timer Operation During Regeneration
IntheRegenerationcyclestepdisplay,thetimershows
thecurrentRegenerationcyclenumberthevalveisin,or
hasreached,andthetimeremaininginthatstep.Onceall
regenerationstepsarecompletethetimerreturnstoInService
andresumesnormaloperation.
Example:12minutesremaininginCycle1
PresstheExtraCyclebuttonduringa
RegenerationCycletoimmediatelyadvancethe
valvetothenextcycleandresumenormaltiming.
Flow Meter Equipped Timer
DuringnormaloperationtheTimeofDayscreenalternateswith
the Error screen (if errors are present).
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.
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
Duringapowerfailurealltimerdisplaysandprogrammingare
storedforuseuponpowerre-application.Thetimerretains
allvalues,withoutloss.Thetimerisfullyinoperativeandany
callsforregenerationaredelayed.Thetimer,uponpower
re-application,resumesnormaloperationfromthepointthatit
wasinterrupted.
NOTE: A ashing Time of Day display indicates a power
outage. Hold the Up or Down button to reset time.
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
lockout.Therecommendedgaugewireis20withamaximum
lengthof500feet.
Regeneration Day Override Feature
IftheDayOverrideoptionisturnedonandtheactualnumber
ofdayssincelastregenerationexceedsthesetregeneration
dayoverridevalue,theRegenerationcyclestarts.Ifotherunits
areinregeneration,itisaddedtoaregenerationqueue.This
occursregardlessoftheremainingvolumeavailable.
WARNING:
This unit is not designed to drive/power
external devices. Transformer must be
grounded. Ground wire must be terminated
to the back plate where grounding label is
located.
Auxiliary Relay Output
TheAuxiliaryRelayOutputonthecircuitboardcanbe
programmedtobeclosedduringawindowoftimewithinthe

TROUBLESHOOTING
Detected Errors
Ifacommunicationerrorisdetected,anErrorScreenwill
alternatewiththemain(timeofday)screeneveryfewseconds.
• AllunitsInServiceremainintheInServiceposition.
• AllunitsinStandbygotoInService.
• AnyunitinRegenerationwhentheerroroccurs
completesRegenerationandgoestoInService.
• NounitsareallowedtostartaRegenerationCyclewhile
theerrorconditionexists,unlesstheyaremanuallyforced
into Regeneration.
• Whenanerroriscorrectedandtheerrornolonger
displays(itmaytakeseveralsecondsforalloftheunits
inasystemtostopdisplayingtheerrormessage),the
systemreturnstonormaloperation.
NOTE: During the error condition the control continues
to monitor the ow meter and update the volume
remaining. Once the error condition is corrected
all units return to the operating status they
were in prior to the error. Regeneration queue is
rebuilt according to the normal system operation.
Or, if more than one unit has been queued for
regeneration, then the queue is rebuilt according to
which one communicates rst.
