Temp control advice

[Joe51]

Veterans,

I just made the jump to TC, and there are a couple things I'm not real clear on. If I lock the resistance at room temperature, what are the affects in moving to a warmer or cooler environment? For example, it was probably 72°f inside the house, and 50°f outside this morning. By July, it will be 75°f in the house and 102°f outside.

I ask because I thought I had my equipment set up how I like it until I left for work this morning. But during the drive to work, I got almost no vapor until the heat in the truck kicked in. Now, it could be that I didn't actually have things set and the keys locked like I thought, but it seems to me that if ambient temperature has such an affect on resistance, then it should be set for the environment it will be used in. For example, if I'm going to be outside all day in July, will I have to keep locking my resistance through out the day as the temperature climbs? If it is left unlocked, wouldn't the temp be calculate based on the base resistance when the mod is fired instead of based on what it is locked at from a temp controlled environment?

I'm using the iStickTC60W with the Melo2 that it came with. I'm learning how it works with the .5ohm ti coil thinking it would be a little more forgiving of mistakes than the nickel coil. Any advice is appreciated.

Thanks,

Joe

Moved this to Temperature Control from Ask The Veterans to see if we can get you some replies

I'm starting to use TC on a couple of my tanks and it seems to me that locking the resistance is pointless and doesn't make sense. I never have locked it in and I've had no problems in TC mode even when I move between environments with big differences in temperature.

Maybe someone that's a little more knowledgeable on TC can chime in and explain the point of it to me.

i have been locking my evic mini to avoid getting the "new/old coil" message. this would happen after chain vaping and heating the tank up, then letting it sit for a minute or so and then taking a hit. the mini would see the resistance being much higher and think i have a new coil in there. i use ti coils and their high tcr value accounts for the large resistance change.

Really not much advice to give...

• wrap your own TC coils - that way you know what wire is in there
• think simple thoughts - a single spaced coil is much easier to get good results with then that 6plex stapled/fused clapton you might be thinking of starting with
• don't try to push the limits of your mod - most will fire a TC coil just fine from 0.1 to 0.7ohms, many of the older TC mods had upper limit of 1.0 ohms in TC mode, now many can fire a TC build at upto 1.5ohms, others even higher
• the "base resistance" is most important. I usually get a reading on the mod the build is intended for and lock THAT resistance in before I dry burn and wick. If you never swap tanks or remove your tank to fill it, you don't have to worry about locking the resistance
• while there might be menu options for Ni and SS317, I personally would not try starting out with ether wire type. Ni200 can be a PITA to work with (only spaced coils, very very low resistance) and SS317 has to low of a TCR for my tastes
• most of the (excepting Ni200) TC type wires can be made into a 'contact coil' but require enough heating to develop an insulating oxide layer on the skin so your coil is not shorted. Some folks just nail the wire with a butane torch while others will carefully pulse 10W or less while working out hot/cold spots in the coil

When you lock your mods resistance, your effectively telling your mod right now the coil is at 70° and this is the resistance. If you lock your resistance after the mod has just been fired ( before the coil gets to room temperature) then it will think whatever temperature it's at when you lock it is 70°F. If this is done then your vapor will be way higher than what it is set. Let's say that the coil is 150°F when you hit the lock button, The true temperature of your coil will be 80°F above what it says it is or what it is set at... Whenever your resistance is locked at room temperature click the button when in temperature control just for a second and the first number that will pop up is 70°F. So basically if you wanted to get your TC work right, lock it when you're in a 70°F environment. Or something close to that.

Ambient temperature probably isn't going to have that big of an effect on how accurate your TC is. Unless the difference is a substantial one, like going from room temperature to below 0C outdoors during winter.

In order for your TC to work properly, you need to lock your resistance at room temperature.

Mods read the resistance of the coils not the actual temperature of the coils. And only by accurately detecting the change in the resistance of the coils when firing is a mod able to regulate the amount of power going into the coils and thus temperature. This is why you're able to manually enter in the TCR values (or TFR) for different wire types that weren't included in the mod.

How accurate the TC is depends on the mod or more importantly the board. Thats why you see DNA200 and Yihi devices going for more than the others.

Just some things I wanted to add to the posts above:

Ime contact coils are pretty problematic for TC, I do not recommend them.

Do not oxidate titanium wire neither, the white titanium oxide is highly toxic. DO NOT dry-burn titanium.

As for locking the resistance, that is just a joke mod-makers pull on us imo. It doesn't seem to make any difference whatsoever if I lock the resistance or not on my Evic VT anyways.

Just set your max wattage, pick a temp you like and vape on imo. No need to overthink things.

No need to overthink things.

but...but...Its what I do best! if I dont overthink random nonsense, then who will?

 

[rice721]

I did notice a less accurate temp control on my dna200 devices without the resistance locked using ss. The mod would show a high temp warning while I get no vapor production.

Haha, I guess you're the needed exception to confirm the rule, go nuts!

That doesn't sound right, I think your mod is defective, send it back ASAP!

I kid of course, & I realize I made a pretty bold statement. But it was the only conclusion I could come to in my limited experience. And even though I really feel it doesn't do anything on my mod I have to admit I am still locking the resistance even if it's just because I'd hate to waste a function

The locking feature is only really useful if you remove your tank for filling.

Even if the tank was only slightly warm when it is removed in an unlocked state the odds are/were that the base resistance would change setting off a chain reaction of all sorts of head aches in attempts to get the resistance to read correctly again.

With the resistance locked the user can remove/install the tank as often as they need without the base resistance changing.

That depends on the device/chip though. At least devices with Yihi boards, and Sigelei devices, require you to lock the resistance in order for tc to function properly. Other than that, it's usually best to leave the resistance unlocked.

With most mods you'd get a new/same atomizer question in that case though.

mileage may vary I guess.
