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.

Inthepoweroperationmodethewattageselectedinthepowersetting
menuisappliedtothecoil,unlessthereisapowerlimitationduetoa
conditiondescribedaboveunder“notestoveryhighpowervaping”.
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TmpCtrl,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“Temp.Cof”isused.Thevalue
oftheselectedcoefficientisdisplayedbehind“Wire”.
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.
…
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.
