Temperature Protection

The DNA40 is the first power supply for electronic cigarettes to directly measure and limit the temperature of the heating coil during operations. By preventing the coil from becoming too hot regardless of fluid, wicking or airflow, a variety of undesirable situations can be prevented. For example, appropriate temperature settings will prevent the wicking material from charring, which compromises taste and introduces unintended chemicals into the vapour. Appropriate temperature setting will also reduce the breakdown of flavoring and base liquid components, which could impact taste or safety.

Evolv's Temperature Protection Technology requires a heating coil made from Nickel 200 alloy, rather than Nickel Chromium or Kanthal alloys. Nickel 200 is commercially pure nickel. It is often sold in vapour shops and online as "non-resistance wire". If the temperature reaches the maximum value, the wattage applied to the atomiser coil is reduced to prevent overheating. Please note that the temperature reading is the average temperature of the atomizer coil so that the temperature is uniform, without hot or cold spots. Ensure that the coil does not short to itself.

Because wattage, not temperature controls vapour volume, large vapor volumes can be produced without unnecessarily high temperatures. Temperature Protection is also helpful if the atomiser begins to dry out, the user pauses during a puff, the beginning or end of the puff, or if the wattage setting is inappropriate for the attached atomiser.

In normal operation, when the device is not firing the maximum temperature setting is displayed on the screen. When the device is firing, the actual average temperature of the coil is displayed on the screen.

By default, the Temperature Protection setting is 232°C Fahrenheit. To change the limit:

1. Lock the device by pressing the Fire button five times.
2. Hold down the UP and DOWN adjust buttons for two seconds.
3. After two seconds, the maximum temperature will be displayed, and the UP and DOWN buttons should be released.
4. Use the UP and DOWN buttons to adjust the maximum temperature.
5. When the display shows the desired maximum temperature, press the Fire button to exit temperature adjust mode. The Maximum temperature is adjustable between 200 Fahrenheit and 600 Fahrenheit. To disable the temperature protection entirely, adjust the limit up to 600 degrees, then press the UP button one additional time. The temperature limit will read OFF. This will also disable the prompt when a new atomizer is attached.


When the DNA 40 is used with a temperature sensing atomiser, an additional feature called Preheat is activated. No vapor is produced when the temperature when the temperature is below the boiling point of the liquid. Preheat applies extra power until the heating coil is up to operating temperature to shorten the delay between pressing the fire button and generating vapour. Because the preheat is temperature based, it will not overheat or burn the vapour.

Attaching a new atomiser

The DNA40 used the resistance of the atomiser to calculate the temperature of the heating coil. It continually looks to see whether a new or changed atomiser has been connected. If you are using temperature protection, be careful to only attach new atomizers that have cooled to room temperature to the device. If a new atomiser is attached to the DNA40 before it has cooled down, the temperature may read and protect incorrectly until the new atomiser cools.
When you connect a new atomiser or disconnect and reconnect your existing atomiser, the DNA40 will prompt you to confirm this change. When you fire the first time, before activating the DNA40 will prompt "New Coil? UP YES/DOWN NO". When you see this prompt, if you have attached a new atomiser, press the UP button. If you have disconnected and reconnected the same atomizer, press the DOWN button.


Basic operation of the DNA40 is as follows. To wake the device from power off state, tap the Fire button. To generate vapour, press the Fire button. To change the wattage setting for more or less vapour, click or hold the Up and Down buttons.


The DNA40 has a small .69" diagonal blue OLED screen. The screen is attached to the main board by a flexible cable, allowing freedom in the design of your device. Please use caution when handling the screen and design the device so that the cable will be secured or strain relieved in operation. The normal and special operating modes shown on the display are discussed below. The DNA40 will automatically detect whether a temperature sensing (Nickel 200) or standard (Kanthal etc) coil is attached.

Temperature Protected

Watt Setting: The power level currently set on the DNA40. Battery indicator: The current state of charge of the battery.
Temperature Display: When not firing, the maximum heating coil temperature setting. While firing, the actual temperature of the heating coil is displayed.
Ohms Display: The resistance of the atomizer attached to the device. This is measured only when the unit is supplying power to the atomiser. At other times, it shows the most recent measurement.


Locked mode: Pressing the fire button five times with less than .7 seconds between presses will cause the device to enter Locked mode. In Locked mode, the device will not fire and the output power will not adjust accidentally. While in Locked mode, the screen will be off, except that pressing a button will show "Locked, Click 5X". To exit Locked mode, press the fire button 5 times.
Stealth mode: While locked, holding the fire and down buttons simultaneously for five seconds will switch to stealth mode. In this mode the display is off. It will still show error and lock messages. To switch back to normal display mode, hold down the fire and down buttons simultaneously for 5 seconds. This setting is internal flash memory, and remains if power is removed.
Right mode and left mode: While locked, holding the fire and up buttons simultaneously for 5 seconds flips the display. This allows for maximum flexibility in designing the mod, as well as accommodating left handed use. This setting is stored to internal flash memory, and remains if power is removed.
Power locked mode: Holding down both the up and down buttons for two seconds will place the device in Power Locked mode. In this mode, the mod will operate normally, but you will not be able to change the power setting. This mode prevents accidental power level changes due to the button being pressed while in a pocket. To exit Power Locked mode, hold the up and down buttons for two seconds.
Max temperature adjust: From Locked Mode, holding down both the up and down buttons for two seconds will placed the device in Temperature Adjust mode. Once this mode is entered, the max temperature will be displayed. The up and down buttons are used to adjust the max temperature. To save the new temperature setting and exit, press the Fire button.

Error Messages

The DNA40 will indicate a variety of error states.
Check atomiser: The DNA40 does not detect an atomiser, the atomiser has shorted out, or the atomiser resistance is incorrect for the power setting.
Shorted: The atomiser or wiring are short circuited.
Weak battery: The battery needs to be changed, or a higher rate battery is needed to be used. If this happens, the DNA40 will continue to fire the atomiser, but will not be able to provide the desired wattage. The Weak Battery message will continue to flash for a few seconds after the end of puff.
Temperature protection: The heating coil reached the maximum allowed temperature during the puff. If this happens, the DNA40 will continue to fire, but will not be able to provide the desired wattage.
Ohms too high: The resistance of the atomiser coil is too high for the current wattage setting. If this happens, the DNA40 will continue to fire, but will not be able to provide the desired wattage. The Ohms Too High message will continue to flash for a few seconds after the end of puff.
Ohms too low: The resistance of the atomiser coil is too low for the current wattage setting. If this happens, the DNA40 will continue to fire, but will not be able to provide the desired wattage. The Ohms Too Low will continue to flash for a few seconds after the end of a puff.
Too hot: The DNA 40 has onboard temperature sensing. It will shut down and display this message if the internal board temperature becomes excessive.

Auto Power Down

The screen will be at full brightness while firing. After 10 seconds with no button pressed, the screen will dim. 30 seconds after the last button press, the screen will fade out and the device will go into sleep mode. To wake the device, press the fire button.

Because of the machining process of the material (billet 6061 aluminum), along with the chemical reaction anodizing has on the effect of the material, some imperfections may arise.
