GENERAL OPERATION
SteffesETSroomheatingunitsutilizeoffpeakelectricityavailableduringthosetimesofthedayornightwhen
thePowerCompanycansupplyelectricity moreeconomically.Duringoffpeakhours,theroomheatingunit
convertselectricitytoheatandstorestheheatinitsceramicbrickcore.Theheaterstoresheatatvaryinglevels
dependinguponoutdoortemperature,ownerpreference,utilitypeakconditions,andtherequirementsofthe
spacebeingheated.
Asmallamountofheatisradiatedthroughtheheater’scabinet;however,mostoftheheatingisaccomplished
byathermostaticallycontrolledblower.Whentheroomtemperaturesensorsensesatemperaturebelowthe
roomtemperaturesetpoint,theblowercirculatesroomairthroughthebrickcore.Thisairisheatedanddis
chargedbackintotheroomtomaintainaconstant,comfortableroomtemperature.
Onstartup,odorsrelatingtofirsttimeoperationoftheheatingcomponentsmayoccur.Therealsomaybean
odorassociatedwithdustaccumulationiftheheaterisshutdownforanextendedperiodoftime.Allowthe

ROOM TEMPERATURE CONTROL
Theroomtemperaturesetpointisadjustedbypressingtheuparrowtoincreaseorthedownarrowtodecreasethe
setpoint.Whentheheatersensesaheatcall,thevariablespeedblowerisenergizedandcirculatesroomair
throughthebrickcore.Thisheatedairisdischargedintotheroomtomaintainthedesiredtemperature.Inan
efforttokeeptheroomtemperatureconstant,theblowerautomaticallyadjuststotheappropriatespeedandmay
continuetooperateafterthesetpointhasbeenreached.
Iftheownerpreferstomonitorroomtemperatureatapointawayfromtheheater,anoptionalremoteroom
temperaturesensorisavailable.Aremoteroomsensoralsoprovidesmoreevenheatdistributioninanareawhere
morethanoneheaterisinstalled.Itisrecommendedtousetheoptionalremoteroomsensorinapplicationswhere
therightsidepanelhaslessthana12"clearanceorwheretherightsideoftheheaterisexposedtoabnormal
temperatureconditionssuchasdraftsfromadoororwindow.
TURNING HEATER "OFF" AND "ON"
Turningtheheater"OFF"suspendsallfunctionsoftheheater.Toturntheheater"OFF",usethedownarrowto
decreasetheroomtemperaturesetpointuntil"OFF"isdisplayedonthefaceplate.Toturntheheater"ON",use
theuparrowtoadjustroomtemperaturesetpointtothedesiredtemperature.
The heater MUST remain "ON" if being used to supply a peak control signal to other con
trolled loads.
BRICK CORE CHARGE CONTROL
Theamountofheatstoredintheheater’sbrickcorecanberegulatedbyautomaticormanualchargecontrol.The
heaterisfactorypresetforautomaticchargecontrolregulation.Ifmanualchargecontrolisdesired,theheater
mustbereconfiguredatthetimeofinstallation.
AUTOMATIC CHARGE CONTROL
Withautomaticchargecontrol,thebrickcorechargelevelisregulatedautomaticallyinrelationtooutdoortempera
tureandtheheatingrequirements.AnoptionaloutdoorsensororSteffespowerlinecarrier(PLC)systemis
required.TheoutdoorsensororPLCsystemmonitorsoutdoortemperatureandprovidesthisinformationtothe
heater.Theheaterrespondsbystoringheatinthebrickcoreaccordingly.Nouserinterfaceisrequiredtoadjust
thebrickcorechargelevel.
MANUALCHARGECONTROL
Ifmanualchargecontrolisbeingused,thebrickcorechargelevelmustberegulatedbytheuser.Duringthe
heatingseason,theuserneedstoperiodicallyadjustthebrickcorechargelevelsettinginrelationtooutdoor
temperatureandtheheatingrequirementsofthearea.Toconfiguretheheaterformanualchargecontrol,referto
theConfigurationMenu(Page2.09).

MAINTENANCE AND CLEANING
Aswithmostheatingsystems,airborneparticlesandodorsintheroommaybedrawnintotheheatingsystem
andoxidized.SincetheroomairpassesdirectlythroughthehotbrickcoreoftheETSheater,theoxidation
processwillchangethepropertiesoftheseparticlesandodors. Odors canbe amplified; thus, itis recom
mended not to operate the heating system if odors such as those from
paints, varnishes,or chemicals are present in the air. Allow the area to
becompletelyairedoutbeforeoperatingtheheater.
Asforairborneparticles,aftertheyhavebeenoxidizedtheyareexpelled
backintotheroomandmayaccumulateontheheaterorothersurfaces.Over
time,theseparticlesmayappearasablackresidue,commonlyreferredtoas
soot.Highconcentrationsofairborneparticlesfromsuchthingsasaerosols,
dust,candles,incense,pethair,highhumidity,smoke,orcookingcancon
tributetopoorindoorairqualityandacceleratethisprocess.Tominimize
theblackresiduebuildup,cleantheoutersurfaceoftheheateronaregular
basis.Washthecabinet,onlywhencool,withanonabrasivehousehold
cleaner.Donotusescouringpowdersorfurniturepolish.Steffesrecommendsusing"SoftScrubwithBleach"
brandcleanseroranequal.
Regularlyvacuumaroundallsidesoftheheater.Checkthebackoftheheatertomakesurenoobjectshave

INSTALLER'S FINAL CHECKOUT PROCEDURE
Step 1 Withtheheaterdeenergized,hingetherightsidepanelopen.
RefertoHingingtheRightSidePanel(PageA.08)forinstruc
tions.
Step 2 Inspectallfieldconnectionstoensuretheyaretightandthatall
wiresareroutedcorrectly.ETSdevicesrunforlongperiodsof
timeathighelectricalloads.Poorormarginalconnectionswill
causetheconnectionstooverheatandfail.
ClassII (lowvoltage) wiring or any wiring notratedfor
line voltage should never be installed in a line voltage
area.
Step 3 Check the damper systemto ensure the damper operatesfreely
andthatthereisnodebrisinthisarea,whichcouldinhibitits
operation.Todoso,manuallypressthedamperleverextending
fromthedamperdownward. Becarefulnottobendthedamper
actuator.Ifthedamperisnotfree,removetheblowerandcleananydebrisfromthatarea.
Step4 Placetherightsidepanelbackintopositionandsecure.
Step5 Returnthecontrolcircuitboardtoitsoriginalpositionandinstallthepaintedfrontpanel.
Step6 Energizetheheater.Makechangestotheheater'sconfigurationsettingsasnecessary.Refertothe
ConfigurationMenu(Page2.09).
Step7 Makesurethebloweroperatesbyadjustingroomtemperaturesetpointabovetheactualroomtem
perature.
Step 8 Withthesysteminanoffpeak(charge)mode,initiatethechargecontroloverride.(Page1.03).
Step 9 Check forproperamperage draw
onthechargingcircuit(s).Usethe
Charge CircuitAmperage Draw
Chartfor reference tothe correct
amperageof the specificheater
beinginstalled.
Step 10Makecertainallfusesand/or
circuitbreakersarelabeledinthe
distributionservicepanelasthis
system maybe connected to more
thanonebranchcircuit.
Step11 Verifythattheheaterreceivesand
respondstotheutilitypeakcontrol
deviceandthatallothersystem
controlsareoperatingproperly.
Step 12Presentownerwiththemanualand
warrantyinformation.Theowner's
registrationcardmustbecompleted
andreturnedtoSteffesCorporation
toensurewarrantycoverage.Theownershouldretainthetopportionofthecardfortheirrecords.
Step 13Takethetimeneededtoinstructtheowneronhowtooperatetheheater.Manyservicecallswithnew
ETSsystemsarearesultofownerconfusiononequipmentoperation.Thetimespentintraininggreatly
reducesthechanceofacallback.
