What is Temperature Control | Vaping Basics [Guide]

For many vapers, temperature control is an obscure concept. From the very beginning, it was perceived as a vape technology that could revolutionize the functionality of electronic cigarettes, but this option, which is today found in most electronic devices, is not as successful as expected.

Vape Technology

On paper, temperature control is a real step forward. As a reminder, the principle of temperature control is as follows:

Ohm Reader: An electronic mod contains an ohmmeter.  A vape device capable of measuring the impedance of a resistance coil’s numerical value.

Wire Type: Some materials available among the different resistive coils have the possibility of having a variable impedance depending on the temperature of the material.

Temperature Reader: By analyzing the impedance variation thanks to an ohmmeter, the electronic mod is able to interpret the temperature of the resistive wire. In other words, through the reading of the impedance, the resistor works as a thermal probe.

Temperature Threshold: The temperature control option of a vaping mod allows the user to specify a threshold. You set a temperature not to exceed. The mod automatically interrupts heating when the resistance reaches the specified temperature.


Limiting the heating prevents any significant temperature spike. So to prolong the life of the resistance coil by keeping the thermal stresses under a controlled threshold.


A dry, or not sufficiently soaked, resistance heats up abnormally. That is to say that the mod will interrupt the heating immediately if the supply of liquid is insufficient. This significantly reduces the risk of heating the dry wick and accidentally burn it.

From the point of view of the creativity of the principle as of its use applied to the electronic cigarette, the temperature control feature is a major innovation. It allows resistance control in traditional Kanthal. More stable, increased longevity, a better-controlled vape, temperature control keeps its promises.

Temperature Control Complexity

The flip side of the coin is that the very principle of the application of temperature control lies in the interruption of the heating.

However, for the interruption to occur at the right time, it is necessary to correctly set the feature inside the vaping mod. If the latter is not set accurately, the system can simply refuse to function, and control the power with each puff based on resistance coil temperature.

Under these circumstances, it can be risky to get into an electronic cigarette with a single e-cigarette set up just for temperature control. More still in the phase of stopping smoking – critical moment where the nerves are fragile and the need to have to negotiate with the parameters to release a puff can be very annoying. When starting the temperature control, make sure to have a backup atomizer. It must be mounted with kanthal resistance as a safety net.

Think during your first steps with the temperature control to regularly check your settings. The complexity of the setup is only because there is no good way to go. Neither pre-settings available as the variables must be filled in according to your way to vaping. Thus the frequency and duration of the puffs, the relative preference to the opening of the airflow. But also the viscosity of the e-liquid and the nature of the flavors.

Setting Up a Temperature Control Feature

To begin, make sure you have a mod that can support temperature control. On this mod must install a tank with a resistance dedicated to temperature control.

Three possibilities that are compatible with Temperature Control:

  1. Nickel (Ni200)
  2. Titanium (Ti)
  3. Stainless Steel (SS)

These three coils are the most common. If you decide to explore the world of temperature control in more detail, you can try other types of wire later, like the NiFe.

Be sure to identify the type of wire that makes up your resistance. Each material has its own impedance/temperature coefficient. The Nickel Temperature Control mode with titanium resistor poses three problems. Namely an erroneous temperature reading, a system not working properly, and resistance likely to wear out very prematurely. In general, the type of resistor is mentioned either directly on the wall of the latter or via a color code. In case of doubt, it is always good to consult the pages dedicated to the resistances of our website.

Calibrate Resistance Coils

Once the type of temperature control selected is appropriate for your selected resistor, most electronic mods let you “lock” in your resistance.

As mentioned earlier, a compatible electronic mod with temperature control is capable of interpreting a thermal differential from a change in impedance. However, your mod is not a thermometer. It lacks an essential variable: the ambient temperature. That is the temperature at which resistance must be found when it has not been used. The calibration is a critical phase of temperature control. Providing your mod the essential key to an accurate reading of the temperature.

Most of the electronic mods equipped with temperature control offer a calibration function. Some will even impose it on the slightest detection of abnormal variation of the resistance.

So make sure your resistance is at room temperature during this phase. For this, the resistance must not have been used for at least 15 minutes. Then beware of sudden changes in outside temperature. If it is 35 ° C outside and you lock your resistance in an air-conditioned room at 23 ° C, the reading of your resistance may be distorted. It is then necessary to anticipate situations to take advantage of precise temperature control over the length. Do not hesitate to re-calibrate the resistance if necessary. And this after having waited that this last one finds a room temperature.

Set the maximum temperature control threshold before shutdown

This threshold is a numerical variable expressed in ° C or ° F. By default, the “plus” and “minus” control buttons allow you to configure the threshold when you are vaping on a temperature control mode. This threshold indicates the maximum temperature that your resistance will be able to reach before your box automatically cuts the heat. Expressed more simply, you indicate to your mod “I do not want my resistance coil to heat beyond such temperature”.

We understand here all the interest of the previous steps. If the CT mode is not suitable for the type of resistor, or if the resistor is not cold calibrated, this results in an interpretation of the distorted temperature. As for the threshold, it does not mean anything.


  • I have a titanium resistor mounted in my atomizer.
  • I inadvertently chose a temperature control mode for nickel.
  • I heat up my resistance to try to make everything work before calibrating it.
  • The threshold, I set it to 215 ° C.
  • My resistance is at 180 ° C (real value). Yet due to inaccuracies in my settings, my mod considers that it is at 240 ° C (interpreted value).
  • The cut takes place automatically because 240 ° C> 215 ° C, so it is impossible for me to vape.

Anyone who would be tempted to retort that it is enough then to raise the cut-off point beyond 290 ° C does not integrate the logic behind the temperature control. By raising the threshold, the final result appears functional. But similar to that produced with kanthal resistance and a direct power mode. In other words, it would be equivalent to having the disadvantages (parameterization) of the temperature control without its advantages. Namely the preservation of resistance and protection against dry-hit.

As previously indicated, the threshold setting is tricky. And this because the ideal threshold depends on your own habits. Each vaper finds its ideal threshold by groping and experimenting. A well-configured threshold will simply cut the heat when the resistance is in danger. And without making an untimely break when you seek to vape under normal conditions.

Nevertheless some generalities that can help you find the right threshold for your style of vape:

As a general rule, we recommend setting the threshold around 230 ° C to begin with.

Depending on the specification of your resistance coils, it will be more or less resistant to heating. These specifications are the liquid supply capacity, the single/double resistance aspect, and the impedance. The goal of the game is to find the threshold most suited to the capabilities of your resistance. All while meeting your style of vape.

A more viscous liquid (loaded in VG) takes longer to imbibe the resistance. The latter is therefore more prone to overheating (dry heating) with a thick e-liquid with a fluid e-liquid. It can be interesting to lower the threshold and the power when the rate of LV is high (> 50%)

More spacing between each puff is short (chain vaping, or sequence of puffs) plus the resistance undergoes thermal stresses. Conversely, if you tend to space your puffs, you can raise the threshold slightly.

A fully open air flow (airflow) means more air circulation. And therefore better cooling. If you tend to vape with open airflow, you can raise the threshold slightly.

As long as you have made the correct settings, just follow these guidelines to adjust your settings:

As soon as you notice an unusual taste of burning, consider that your threshold is too high compared to your style of vape.

Conversely, if the cutoff is triggered very often, your threshold is too low.

If your resistance seems to wear/burn too quickly and the cut is triggered very often is that your style of vape (power setting, choice of liquid, frequency of puffs.) Solicits too much your material (resistance) compared that the latter has been designed to support. You can either discipline yourself to vape less and less often, or opt for more suitable equipment.

Temperature Control Power

The temperature control options are only used to configure security in addition to the standard settings. And this except some very rare exceptions as for mods constant temperature. It remains to set the power of your mod, as in a conventional direct power mode.

Of course, the power and threshold settings are complementary. It is, therefore, preferable to have a good appreciation of one’s personal preferences in terms of power. Why? In order to configure the threshold accordingly.

It is not advisable to set the power to unreasonable levels to confirm that the threshold is working properly. Any adjustment must be smooth, gradual, and smooth. Indeed, as long as the settings are slightly inaccurate, the cut can be triggered a little too late. And, another consequence, the resistance may be instantly put out of service.


A temperature control feature is a great tool. As much for its technological application as for the many advantages it brings to a vape experience. However, the transition to temperature control should not be done expeditiously. To control the temperature control indeed requires a work of analysis of its waiting. As well as a work of analysis of its own style of vape in order to arrive at coherent adjustments.

We advise the transition to temperature control to vapers already comfortable with the electronic cigarette.  These vapers can fumble without nervous breakdown through the different settings to find their happiness. Well controlled, the temperature control also works wonders on an atomizer rebuildable. It can even open new perspectives on your vaping technique.
