My DNA200 is having issues with Temperatue Control, with no regards to type of wire. I've tried a couple of different atomizers and disposable coil heads for a couple different tanks. I will either get no read out of temperature (as if I had attached a non-temperature sensing coil), or one that is incredibly off, such as firing at 0.1W and reading a temperature of 800F, while the coil is cold. The resistance reading also seems to be off. If I install a coil into one of my tanks that has a resistance of .12, I'm getting a reading of .30-.40 cold. Could this be a short/ground or something to the 510? Can I fix this myself, or do I need to get it worked on? Is it the board? The device works fine in normal Kanthal power mode. But I've had very little success with temperature control on the device. Is this something I can fix myself?

Lately, the device is not recognizing temperature-sensing wire at all. It seems to think everything is Kanthal.

Has the mod resistance on the mod tab been set to the wrong value, if it is set make a note of the value and then try it with the mod resistance set to zero.  It's on Mod tab in Escribe.

Well, I talked to Nick with customer service at Evolv, and he's saying it sounds like a 510 issue. I'm going to contact Flawless, who made the box, and see what they say or can do to help.

Also, the mod resistance was already set to 0.

Same issue, tried 10 or so builds, brand new device. TC has not worked yet with ni200 or TI everything fires as kanthal regardless of profile set. Caught fire in my mouth at work, these seem to be pretty shabby boards.

Can you give an example of a build that won't work in TC mode?  What wire, starting resistance and atomizer?  Typically TC mode failure is usually the 510 connection or atomizer.

Though it has been stated many times on this forum, if your 510, its associated wiring or your atomizer has a substantial initial resistance, and your build is very low resistance, then the change in resistance the mod sees will be small as a percentage and therefore it will assume the wire is non-TC wire.

I think you've made something wrong. You use a Reuleaux that i can see from ECF.
Be sure to run the latest EScribe Software and load the latest Firmware according to:
http://www.wismec.com/product/reuleaux-dna200/
You can also load the setting file.
First you can control the resistance of your atomizer with Atomizer Analyzer.
If you change settings don't forget to klick Upload Settings to Device.
Another method is to go to Device Monitor to control your Settings.

Try it and be Patient, it's worth [smile]

Any build that is not Kanthal. Lets see...

Single 28g ni200
Single 26g ni200
Dual 28g ni200
Dual 26g ni200
Ni200 clapton 26/28
Ni200 clapton 28/30
Cci triforce prebuilt coil head at .1 ohms, tried 2 of them.

For attys using a velocity clone and a Alliance.

Downloaded the settings from Wismec and uploaded the .ecig file to device before I even had my first vape.

I've used the atty analyzer but i'm unsure of what it does. I thought it was more of a test, says that resistance should change on tightening. The atty does jump around so i figured it was ok, i dont remeber seeing an option to save or whatever but i was drinking and very tired. Ill check that again later.

Any other ideas before i ship it off? Again, it worked ONCE on my second build for a few hours at night and in the morning using 28g dual ni200. I switched on the tank to drive to work and after that all went to hell tc has never returned. My builds are pretty solid, i can usually spot a defect on my part, post holes are tight on the velocity, stripped one of the screws second guessing myself. Been about 12 hours of frustration over the past 2 days, i am out of ideas.

do simple 5 wrap single coil and dont over tighten the screw ffs, it's not kanthal... 

Before screwing the atty on, do a hard reset.

That doesnt work,warranty

i dont know if you have figured it out or not but this is a bug that can be worked around. My friend and i both have the same issue with our lava boxes with correct settings. Its just an annoying bug that will be fixed. We dont know what causes it. SO lets get to the steps....


1. put on your atty with desired build click yes for new coil 
2. set watts to desired setting
3. fire mod for quick sec. does it display temp readout? obviously not.

this is where fixing it comes in

4. lock device and turn off temp by scrolling all the way up, not down
5. unlock device
6. fire device
7. re lock device and set temp do desired setting 
8. unlock and fire, the device should be reading your temps correctly now 

if this doesnt work, instead of setting watts to desired setting in step 2 set them to 1w and fire the continuing the process and set watts to desired setting before firing in step 8.


I have been looking literally everywhere for someone else who knows about this bug instead of just saying MOD ISSUE WARRANTY SEND IT BACK. My friend and i have not been able to figure out which setting is causing this so we believe it is just a programming bug. Im scared this bug wont be caught and fixed for a while because its so unknown, which really sucks because its f*cking annoying locking and unlocking and resetting everything multiple times. i dont really know how to explain this bug, everyone looks at me like im crazy when i say its just a bug and dont believe me and have some reason why its not. is there a point in posting to "report a bug"? im new but a lot of it seems largly just community and not the developer of the chip giving a fuck. 

best of luck and hope your DNA200 is still in your hands and not on the wind powered sail boat back to the supplier.

CanadianCough's workaround worked for me on a VS. My temperature control issue starts after I have been chain vaping and the next and subsequent pulls are weak and anemic. I have noted when the issue happens that the resistance of the NI200 coil decreases by .01 to .03 ohms and then stops changing. Might be an issue with how the board automatically continues to refine the resistance of the coil and how refinement affects temperature control operation. I hope Evolv issues a fix soon - work arounds are a pain; especially when you consider the cost of a DNA 200 mod.

I don't use temp control much (or at all because it's never been a good vape for me) but I picked up a Smok TFV4 TF-STC2 coil for kicks.  I have to hard reboot through escribe to get temp control to work at all.  It may just be this coil but at 60w temp set at 420F I don't even reach 200F.  

I tried everything but the only thing that made it kick into temp mode for me was the hard reboot.

I too would like to see more individuals who think they have this issue describe it.  Thus far, every "out of TC mode" issue I have had could be traced back to to high or variable mod/atomizer base resistance, i.e. I was able to fix it.

My experience on using titanium wires on my VS DNA200. My build, 24awg on a 3mm diameter bit, .28 ohms on a deck B squape. Yesterday I was using this set up on my sx mini m mod working flawlessly, halfway on my tank. I mounted it on the VS DNA 200, it worked perfectly too, so good I finished my tank. I made the same exact build, same ohms but its not firing well, temperature seems weak. I tried the procedure above just now and its now working well again.
