Under D4 there are 4 other components in the white box. Can you please get a super close up picture of that section or read what the labels are? I can see from the picture you posted that one of them is labeled r2.

I have experienced where if the mod was cold (maybe outside in 60F weather) it would hit harder, and conversely if the mod was hot (like sitting inside of a car) it hit a little weak. +/- 10-20 F usually brings it right back in line for me.
@atroph: Well if the RX200 also knows what the ambient air temperature is (the only right way to do TC IMHO), then everything is fine (why didn't you say that in the first place, or did you?). I guess you would still be in trouble running outside with your nice warm mod and attaching it to your freezing 0°F atty in your car (or the mod is out in the car and the atty came from inside). But how often would that happen anyway?![]()
I agree with certain points made by BillW50 as well as atroph.
I believe the board uses internal resting temp in relation to the coil resistance to set a baseline.
atroph, I believe I can also explain to you why your cold coils hits extra hard in the cold... it is because you locked your resistance. Example purposes, all numbers and figures are just that, not real calculations, you build your coil at room temp 70F, coil resistance is 0.10ohm, target resistance for set temp is 0.20ohm. When the ambient temp drops to 40F the mod is still using the 0.10ohm coil resistance that it has been locked it, when in reality the coil resistance should be 0.08ohm. Now the mod will try and reach 0.20ohm to hit target temp instead of 0.18ohm which is the correct calibrated resistance. Vice versa for hot days or hot ambient temps.
The mod in theory should never assume 70F as ambient temp because climate changes around the world, setting it for 70F as a standard would be incorrect or dare I even say ignorant.
I am not sure how many of you guys had Evic VTC mini back in the day, but they had a huge problem with hitting temp protection and producing no vapor at all in cold weather. I was able to recreate it every time and emailed Joyetech. Every time ambient temp went below 15C it would not produce any vapor and hit temp protection instantly. I think it was due to the way Joyetech calibrated the resting ambient temp to coil temp. After a few emails and test firmwares, they were able to resolve this issue completely.
I also have an example of ambient temp vs coil resistance. I built a coil for my crown rba before I left for my vacation, single 26 gauge ss wire, 0.45ohm. Vaped great in Vancouver prior to boarding the plane. I landed in Thailand and had a ....ty as vape, chalked it up to heat and humidity. I took off the coil, reset the mod, installed the same coil and setup... 0.47-0.48ohm and vaped awesome.
Personally for me, I never lock my resistance on my setups. I actually make it a habit to make the mod learn the coil resistance. My current setup is dual 28 gauge coil at 0.45-0.47 depending on which mod or tank I use. I would install my tank, let it register a the coil 0.45-0.47, fire it till it hits temp at 420, quickly unscrew the tank and screw it back down, get the new coil and say yes, usually around 0.5-0.52ohm. I would wait 5-10mins and wake up the mod, this gives the mod and coil time to cool down and correctly calibrate for temp.
These are just my personal opinions and theories, please correct me if I'm wrong or provided incorrect info.
Sorry for the longs post....
If you want to keep using or keep trying the clapton you can always raise the wattage.Thanks for the answerI will go back the simple kanthal asap
