nightwhenthePowerCompanycansupplyelectricitymoreeconomically.Duringo-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 discharged back into the room to maintain a constant, comfortable room

temperature.

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eort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.

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 amplied; thus, it is

recommended 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 contribute 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.Stees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 fallen behind it and the grill area to make sure there isn't anything obstructing air

ow.Checkallsidesoftheheatertobesuretherequiredclearancesarenotbeingviolated.Objects

should never be placed on top of the heater.

Noadditionalroutinemaintenanceisrequired;however,havingaprofessionalservicetechnicianclean

the blower periodically will decrease the likelihood of undesirable blower noise due to dust accumulation.

No heater panel, with the exception of the painted front panel and painted right side panel, can

ever be removed from the heater. Should any other exterior panel(s) be removed, the heater must

be taken out of service permanently. All panels must be in place when operating the heater.

Risk of re. Can cause injury

or death. Violation of the

clearance requirements can

cause improper operation

of the equipment. Maintain

the placement and clearance

requirements specied.

PEAK CONTROL

SteesETSheatingequipmentisgenerallycontrolledbythePower

heaterusingtheSteesPowerLineCarriersystem,lowvoltagewiring,

aSteesTime Clock Module, orlinevoltage wiring. In applications

utilizing automatic charge control, outdoor temperature information

is required and can be received via an outdoor sensor or power line

carrier control.

The2100seriesroomheatingunitisfactoryconguredforusewithpowerlinecarriercontrol.Refer

totheCongurationMenu(Page2.10)forinformationonconguringtheheaterfortheapplication.

POWER LINE CARRIER (PLC) PEAK CONTROL

TheoptionalSteesPowerLineCarrier(PLC)controlsystemhastheabilitytocommunicatewiththe

heater through the existing electrical circuits in the structure. With the power line carrier option, hard

wired low voltage connections from the power company's peak signaling switch connect directly to the

transmitting device. The switch signals peak control times to the transmitter, the transmitter sends

the signal to an unlimited number of 2100 series heaters, which receive this information and respond

accordingly.

Inadditiontoprovidingpeakcontrolsignals,thetransmittingdevicealsoprovidesoutdoortemperature

information, room temperature set back, and anticipated peak utility control signals (if applicable).

AsthePLCsystemisoptional,itmustbespeciedatthetimeofordering.IfutilizingaPLCsystem,refer

totheOwner'sandInstaller'smanualaccompanyingthetransmittingdeviceforinformationonthe

installation and operation of the power line carrier control system.

PLC Communication is very reliable in most applications but can be aected and

hindered by connection method used, electrical layout of the application, operation

of other equipment in the same electric system, dirty power, etc. Stees does not

guarantee eective communication of the PLC system in all applications and is not

responsible for any communication issues outside normal operating malfunctions.

Manual Charge Control ~ Method of

brick core charge regulation where the

owner must periodically adjust the brick

core temperature setting in relation to the

outdoor temperature.

Microprocessor ~ Device on the circuit

board of the heater which stores and

processes the information for controlling the

operation of the heater.

O-peak ~ The time during the day or

night when the power company can supply

electricity more economically and may

electric rate or billing credits for the electricity

consumed during this time. Typically, electrical

usageisnotcontrolledduringano-peak

time. (The heater will provide heat to satisfy

comfort requirements during this time as well

as charge or store heat in its brick core.)

On-peak ~ The time during the day or night

when the power company experiences

a high demand for electricity. To limit

demand, certain appliances are controlled

to avoid usage by them and/or a premium

for the electricity consumed during this time

may be charged to discourage electrical

usage. (The heater is not allowed to charge

or store heat in its brick core during peak

periods.Heatingrequirementsaresatised
