In the Escribe manual under warning messages it states:
"Temperature Protected: The heating coil reached the maximum allowed temperature during the puff. If this happens, the DNA 200 will continue to fire, but will not be able to provide the desired wattage."

This is in the list for WARNING messages. As this is my first DNA200 product, I'm confused as many state the onscreen message that flashes 3 times default on the mod "Temperature Protected", just means the device has reached the temp the user set. There are many other online posts where users are trouble shooting, perhaps connnection issues etc., that mention TP warnings are an example of their problem.

If seeing this message after firing is a GOOD thing, why is it listed as an ERROR message? I know you can turn that message off, but that does not make sense to me.

Also adding to my confusion is on my Titanium coil build .33 ohms, the vapor is the same at 10 watts and 200 watts, while the manual says "wattage" is what effects vapor production, not temperature, and I assume these are related.

Thanks for any help.

Wattage is what affects vapor production, that's true. Provided you aren't encountering the temperature protection, it's approximately proportional. Is your atomizer reaching maximum temperature even at 10W?

The reason it is an error message is that the original intent of temperature protection was to prevent dry hits and/or to keep the coil temperature below the breakdown temperature of the juice components, and otherwise the vape would be identical to normal coils. Preheat was added so people don't have to wait for their juice to reach its active vaping temperature. So, if set up in this manner, you would never get that message except when it prevented a dry hit or other unsafe vaping condition.

The problem is that many atomizers are not designed properly to be able to emit large quantities of vapor without getting dangerously hot. So people run into the temperature protection a lot, and have come to use the temperature protection to achieve 'absolutely the maximum possible amount of vapor for this atomizer, while keeping at a safe level'. That's fair, but it would be better if the atomizer design was such that you never needed to hit such high temperatures to get good amounts of vapor.

Just watching the screen on the LavaBox, even at 10 watts, it gets to my set temp of 470F, very quickly, then of course I see the Temp Protect message, same at 200 watts. So I don't see how wattage can effect vapor much, this on a Subtank Mini, .33 ohm Titanium coil in the RBA.

I know a few devices like the iStick 40w TC mod, DO NOT even allow any wattage adjustments in TC mode, only TEMP adjustments. My first TC device was the IPV D2, with its scaled down YiHi chip, similar behavior in terms of what I'm seeing when I adjust wattage on that and the DNA200. Except it does not flash any temp protect warnings, just regulates the temp, but when the wick gets dry, you get a screen message, "NO JUICE".

I don't mind seeing the DNA200 temp protect message if that's simply telling me everything is working properly, though in its current usage its really no longer a true "warning", more like a confirmation.

I'm still confused as to using the wattage up/down setting, if it makes NO difference in my actual vaping. Perhaps it's just because the added power of having 200 watts available, as well as PREHEAT, which I have left at the default settings? If that's the case, then of course it makes sense to leave my wattage at 10, to have long battery life between charges, no?

Just trying to learn the DNA200, you guys did a TERRIFIC job creating this top of the line chip.

Have you another atty that you can try?  Are your coils spaced coils where the wraps are not touching each other?  Have you ran Atomizer Analyzer and it shows a solid build?

Some Subtanks can be kinda finicky in RBA mode.

Not sure your question. James fron Evolv just wrote earlier that everything I described was working as as designed.

Just asking for a bit of info about your build etc.  Sometimes hot-spots in the coil can cause quick temp protect message.

Different builds, different coil materials, and different tanks. All behave the same in regards to TP messages and wattage settings. Maybe James will followup.

hum,  just took my nickel 0.15 ohm, 400F, 25 watt, 100 watt preheat build down to 10 watts and it took about 10 seconds to hit temp protect (very little vapor also) where it gets there quickly at 25 watts with loads of vapor.

Thinking out loud:  Might run Mod Analyzer and check the Thermal settings shown in EScribe.  If the board was not configured by Lavabox (sent out with default settings) then the temps may be off.  Just a guess.

My Subtank with prebuilt Nickle coil is reading at .12 ohms right now, just put it on. At 10 watts, 450 degrees, takes 3 seconds to hit TP. At 200 watts about 2 seconds. Same amount of vapor. If I want more vapor, I raise the temp. Granted these numbers would be a bit different if the ohms read closer to the .15 the coil should read. Sometimes I cheat a bit, and take the tank on/off and get a slightly higher ohm readout, like now I'm at .13 ohms, more vapor, at same settings. The prebuilt coils are know to have some connectivity issues the way the leads are only captured by the rubber grommets. But on most, at least the ohms don't seem to drift. Not an issue on my RBA builds. Not sure what we have learned here.

I setup the LavaBox with 11.1 volts, 9.99 WH. LavaBox/Volcano does NOT setup the Escribe properly so the user must do it. Something Evolv should demand, as a new buyer without using Escibe will get LOW BATTERY messages, far too soon, see these messages on the net all over the place.

Curious what the Thermal settings are showing in EScribe?  I have no Lavabox.

Where are "thermal" settings in Escribe?

Under Mod tab.

Just saw your update that Lavabox does not set up their device properly.  Definitely should have been.

here you go, not sure how this pertains, it's the defaults I see.

Those are the default setting of the Evolv board as sent to the device makers.  The enclosures are different depending on the design and material etc. and the Mod analyzer is used to properly tune the settings for the board to the device so the most accurate temp can be delivered.  At least that is what I understand.  

I'm thinking this may play a part in what you are seeing.  James can correct me if I'm off base and miss-informed.

I believe this mod is working as designed. It hits the temp I set it for, very quickly. The temp protect message as James wrote was originally designed as a WARNING, though now it flashes in most cases as a CONFIRMATION. Since unlike my IPV D2, I do not see a "No Juice" warning message in Escribe, I assume one gets the same TP message when you are nearing a dry hit, as of now I have not drained my first few test tanks to know.

As far as 10-200 watt vapor control, it seems to be the same as I have encountered with the D2, meaning I see very little difference in vapor production, or change in such. When I asked about this in the D2 thread, I was told that IPV/YiHi used the wattage setting to RAMP up to the desired temperature, faster/slower, and nothing more. While that kind of made sense, I still could not grasp why one would not want the fastest RAMP up time to get to temp all the time, meaning leaving the D2 at its Max of 75 watts. That device has no preheat setting either. And the iStick 40 TC mod, does not even have any wattage adjustment in TC mode! All your vapor output is via temp settings.

I'm not saying anything is wrong or not working properly as I get a good vape at my set temps, just don't see any fine tuning here with the wide spread of wattage settings I have described. Only wish I understood it better.

In power mode, kanthal coil, the wattage controls the vapor volume, very simple and what I am used to from the past. Thanks for your interest. I'm sure James and his team are busy, hopefully I will get a more detailed explanation of how wattage is to be used for vapor adjustment as the DNA200 manual states, or not!
