HeaterControl(Operationmodes)
Themodcanbeusedinupto5operationmodes.Themodecanbeselectedinthismenu:
Thedefaultoperationiseitherpower(0)ortemperaturecontrolledvaping(1).
Withthe“ExpertMode”(ExtendedFunctionsMod-Menu)enabled,additionaloperationmodesare
HeaterProtection(2),P andBypass(4,mechanicalmod).
WithExpertModedisabled,themenuoptions2..4aremaskedout.

0.PowerMode
Inthepoweroperationmodethewattageselectedinthepowersettingmenuis
appliedtothecoil,unlessthevoltagewouldgetgreaterthan11Vorthecurrentgreater
than22A,whichdependsonthecoilresistance.
Forexamplewithacoilresistanceof2Ohmsandapowersettingof80W,therequiredvoltageatthecoil
is12.6V.Sowith2Ohmsthemaximumwattageis60.5W((11V)²/2R=60.5W).
Or,ifthecoilresistanceis0.1Ohmthemaximumpoweris48.4W,because(22A)²*0.1Ohm=48.4W.
Ascanbeseenfromtheexamples,withhighcoilresistancethepowerislimitedbythemaximumvoltage
of11Vandwithlowresistancesbythemaximumcurrentof22A.Thefactisalsoreflectedinthefeature
list:Apowerof80Wisguaranteedfrom0.17to 1.5Ohms.
Resistancesof0.05to5Ohmsarepossiblebutwithareducedpower.
1.Temperaturecontrolledvaping
Inthismodethemodwillregulatethetemperatureofthecoiltothepre-setvalue,
exceptthepowersettingistoolowtoachievethetemperature.Sopleasenoteto
adjustthepowersettingtoavaluehighenough,ifyouchoosetemperaturecontrolled
vaping.Otherwisethetemperatureregulationchangestoatemperaturelimitation
mode.
WhenHCtrlissetto1,themenudirectlyjumpstotheselectionofthewiretype.Here
theusercanselectbetweendicodes-wire(NiFe30),Nickel200(Ni),Titanium(Ti),
severalsortsofstainlesssteel,NiFe48and“Other”.With“Other”selected,the
temperaturecoefficientdefinedintheExtendedFunctions/HeaterMenuunder
item“Tmp.Cof”isused.Thevalueoftheselectedcoefficientisdisplayedbehind
“Wire”.
Forcommonlyusedwires,thepredefinedcoefficentsare:NiFe30=320,Nickel200=620,
Titanium=350,SS304=105,SS316=88,SS316L=92andNiFe48=480.Notethatthereare
differentalloysforTitaniumandStainlessSteelonthemarket,sothepredefinedvalues
candeviatefromtheactualwire-valueyouuse.Inthesecasesitispreferabletochoose
“Other”asthewiretypeandsetthevalueofthewireintheextendedfunctions
heatermenu“TempCof”. Therangeforthecoefficientis050to650.
Ifyouusethedicodeswire(RESISTHERM)itisguaranteedthatthewirewillalwayshavethesame
coefficient,becausethewirewasespeciallydesignedfortemperatureregulationpurposes.Theregulation
accuracyisbestthen,asthecombinationofresistivityandhighcoefficientisverygood.
NoteforusingNickelwire:Nickelhasahighandalwaysprecisetemperaturecoefficient(Ni200).But
Nickelisnotsoeasytohandle,becauseitisquitesoftanditleadstoverylowresistancecoils,because
ofit’shighconductivity.Fortheregulationaccuracysmallestchangesofcontactresistancesduetoatomizer
movements(tightening)ormechanicalthermalelongationsleadtopoorregulationaccuracy.
