Guides & tutorial on temperature control needed

[Q]

What a meant was that I set the wattage higher than I would normally run and allow the temp sensing to lower it, giving me the max wattage that the temp will allow (I think)

Yep you got it and that's what I do, the chip is sorting the watts out for you, you're vaping at temp, just set the watts above the tanks limits. Constant temp at the coil equals a more consistent vape, 1 lug or 5. Temp "control" as oppose to temp "protection", how you had it before, it would of kicked in when the tank started to run dry ie nothing to heat.

Being new to this concept as well, Whats the difference between temp control and temp protection?

The way these chips work is they lower the power to the coil when a certain temperature is reached.

So all of these temp control devices are really just temp protection.

The ohms change in temp builds and the chip reads the ohm change as an indicator of temperature.

So whether you are using 40w or 200w, as soon as the temp limit you set is reached the power is backed off to maintain that maximum temperature.

Hope that helps

Thanks Tom I was thinking I may have made a mistake ordering a device that said 'temp protection', assuming it was temp control. You know 'lost in translation' type of thing.
Panic over.

TBH I think that we can only go as far as calling them temperature limiting as you can still build coils with hot spots. They also vary a lot in sophistication and the speed they monitor & limit the temperature.

[robby]

Another very important factor is in the wicking ability of your coil/wickcombination and it will ultimately determine how much vapor you are producing, too tight a setup and your temp limiting will kick in earlier (less vapor). Of course there are so many variables, wick material, close or spaced coils, VG/PG ratio, ambient temperature etc. My preference is a 4mm diameter coil slightly spaced with Muji cotton. Temp control/limiting is probably the best tool there is for testing out coil set ups.

So what is Temp Control then?

There's no such thing unless you're talking about cooking your juice sous vide using a PID to control the temp.

[Q]

It just allows the coil to reach a (user determined) preset temperature then drops the wattage to hold that temperature, allowing you to more accurately control your vape

Oh I don't know if you'd use PID to control temp in a mod, I do think you could argue TC mods work on the the principle of proportional temp control though with your temp selected being the set point and the resistance feedback dictating the power output to your coil.

No of course you wouldn't because the DNA40 is designed as a temp protected device not a temp regulated one, it's controlling heat by regulating the power.

robby made a excellent point, your temp limiting/protection device is very dependent on your wicking/coil/airflow, get these wrong and all you will see is your mod hitting Temp limiting far earlier than it should, and is an indication that the build is not as it should be.

Yes and no, those things just affect how well they vape as they do in every other e-cig, but not how the device functions more when it steps in.  All these things are important, but for example wick tightness wont effect the temperature, but will effect the vapour production so the temperature of the vapour you inhale and not the temperature of coil.

@scooby is right about "DNA40 is designed as a temp protected device not a temp regulated one, it's controlling heat by regulating the power."   There are some devices that just have a tempreture setting, but I would advise against them it will be like going back to mechs to use your coils to set the power.  390 F on a dual coil genny is miles away from 390 F on a Kayfun.

That`s exactly what I said, isn`t it? . The coil temperature is directly controlled/limited by the wicking ability. What is the difference between temperature control and temperature limiting in practise? In both cases the temperature of the coil increases (device starts regulating and controlling power) when the wicking efficiency is going down.
