a. Feed Rate Adjustment
TheCircuitboardrunsonaoneminutetimercycle.Each
minute,theboardisthinkingaheadtowhatitneedstodo
for the next minute to maintain or achieve the demanded
temperature.Whatyouaresettingonthefeedadjusterdial
isthemaximumamountoffeedtime,perminute,thatyou'll
allow.Thecircuitboardwillmakeitsowndeterminationof
how long to run the feeder, UP TO the maximum as set
on the dial. For instance, a number 4 settingon the feed
adjusterwillallowamaximumof40secondsperminuteof
feed.Iftheroomtemperatureissatised,withonlyfeeding
20 seconds, then that is all the circuit board will run the
feeder. In most tested scenarios, the number 4 setting is
adequate, however, fuel quality may dictate a higher or
lower setting. If you see un-burned or burning coal being
pushedoffofthe grate during ahigh demand period, the
feed rate is set too high. Ideally, you'll want to see about
aninchofashesinfrontoftheburningcoalduringapeak
demandperiod.Settingthefeedratetoolowmaynotallow
thedemandtemperaturetobemet.Keepingthesettingat
#4 or above will work with most batches of coal.Allow a
minimumofonehourbetweenadjustments.
Note: Since the circuit board is feeding as needed,
only adjust the feed rate while maximum demand is
occurring. (Stove Temp Mode, with a temp dial setting
of #7 will create maximum demand.)
b. Mode Selection
Room-Temp mode is the ideal mode of operation if you
wish to maintain a comfortable temperature in the  room.
Astheoutdoortemperatureuctuates,theSuperMagnum
willadjustthefeedratetomaintainthedesiredtemperature
settingintheroom.Forbestresults,besuretheroomsensor
is located outside of any drafty areas and not positioned on
theoorornearanexteriorwall.
Stove-Tempmodeismoreofamanualmethodofoperation.
Thestovewillrunataconstantheatoutput,regardlessof
outsideairtemperature.Notethatonthecoldestdays,your
indoor heated space will be cooler than on the warmer
days.Theonlyrealbenettothismodeofoperationisthat
you'llbeabletoknowexactlyhowlongahopperfullofcoal
willlast,becausetheconsumptionisgoingtostayrelatively
thesame.
c. Temperature Dial
Thetemperaturedialisadualpurposedial.InRoom-Temp
mode,youselecttheroomtemperatureyouwantthestove
to maintain at the room sensor probe. This is marked in
fahrenheit scale from 50 to 90 degrees. In Stove-Temp
mode,youselectatemperaturesettingbasedonthe#1-7
with1beingaminimumburnand7beingamaximumburn
rate.
d. Blower Speed Adjustment
ThemodeselectorisalsomarkedwithaLtoHscale,ineach
mode.Thisisa variable speedcontrol for the distribution
blower. L is the low setting, and H is the high setting. It
isimportanttonotethattheblowerwillnotcomeonuntil
theESPreachesahighenoughtemperaturetoensurethat
coldairisnotbeingblownoutintotheroom.Also,thespeed
oftheblower,whensetonlowerspeeds,willautomatically
increaseasthetemperatureofthestoveincreases.
