IMPORTANT INFORMATION ABOUT THE
CONTROL PANEL
SQ1
Thecontrolpanelsystemmaintainsheatertemperaturetobetween45to55degrees
Celciusandswitchesthemotoronandoffasrequired.TheHeaterontheSQ1ispreset
andyoucannotchangethetemperature.
Thereare3LEDindicators.TheHeaterlightcomesonwhenyouswitchonthefountain
anditwillstayonuntilthetemperaturereaches55degreesanditwillgooffasthecontrol
panelcutsofftheheateranditwillcomesonagainwhenthetemperaturereaches45
Degrees.Thiscyclewillcontinueuntillyouswitchofftheswitch.
TheMotorlightwillcomeonwhenthemotorisswitchedon.Pleasenotethemotorwill
onlyturnononcetheIndictorstopsashing.Themembraneswitchpanelhasapush-
buttonON/OFFswitchthatcontrolsthemotor.
SQ2 and SQ3
Thecontrolsystemswitchesthechocolateheateronandoffsoastomaintainthe
temperatureatapre-setlevel,andswitchesthemotoronandoffasrequired.
ThereisatwodigitLEDdisplaytoindicatethetemperatureindegreesCelcius,andalso
twoindividualLEDindicatorswhichlightwhentheheaterandmotorrespectivelyareon.
Amembraneswitchpanelhasapairofpush-buttonswitchesforUP(+)andDOWN(-)
tocontrolthetemperature,andathirdpush-buttoncommandstheON/OFFstateofthe
motor.
1) SETTING THE TEMPERATURE
Wheneitherofthe(+)or(-)push-buttonsispressedthesystementersthetemperature
settingmodeandthedisplayshowstheexistingunchangedsetpointtemperature.The
twodisplaydecimalpointsashonalternatelytoconrmthatthetemperaturesetting
modeisenabled.Furtherpressesofthe(+)or(-)push-buttonscausethetemperature
tobeincreasedordecreasedrespectivelyby1°Catatime,butifeitherpush-buttonis
heldforlongerthantwosecondsthetemperatureisraisedorloweredcontinuouslyata
rateof3°Cpersecondforaslongasthepushbuttonisheld.Ifthetemperaturereaches
99°C,furtheruseofthe(+)push-buttoncannotalterthetemperaturefurthernorifthe
temperaturereaches0°Cthe(-)push-buttonwillnothaveanyeffect.
Ifneitherpush-buttonisoperatedforlongerthanthreeseconds,thesystemautomatically
comesoutofthetemperaturesettingmodeandtheashingdecimalpointsturnoff.At
thesametimethenalsettemperaturevalue(TSET)isstored.Thisvaluewillberetrieved
andsubsequentlyusedwhenthefountainisnextswitchedon.
2) TEMPERATURE CONTROL
Whenthefountainisswitchedon,theheaterisalwaysintheONstateinitially,andthe
HeaterLEDisilluminated.Thetemperaturewilluctuatearoundyoursettemperature,
thusthehysteresisbandis2°C.Ifthetemperaturesensorfails,orisun-pluggedfromthe
controlboard,theheaterandthemotorarebothswitchedOFF,andthedisplayshows
‘SF’(SensorFault).
3) MOTOR CONTROL
Whenthefountainisswitchedon,themotorisalwaysintheOFFstateinitially,andthe
MotorLEDisoff.ThemotorsubsequentlyrunsONwhenthe( ON )push-buttonispressed,
andtheMotorLEDisilluminated.Subsequentoperationofthe( ON / OFF )push-button
togglesthemotorandindicatorbetweentheONandOFFstates.
However,ifwhenthemotorissettobe( ON )themotorwillonlystartwhentheactual
temperaturegetstowithin10°Cofthetemperaturesetusingthecontrolpanel(eg.
Fountainsetat80°Cmotorwillonlyfunctionwhenactualtemperaturereaches70°C).In
thisevent,thedisplayshows‘LT’(Lowtemperature)fortwosecondsbeforeitrevertsto
