The user manages the temperature with breath control. This tends to be a far more practical, responsive, and reliable "feedback circuit" than anything that could be built digitally -- especially when different users have different needs. It tends to get around the parallel problems of "is it set right?" and "one setting for everyone" somewhat automatically.
Our recommendation is to ensure that the lips are placed a little above and below the draw hole and to receive the vapor in whole form into the open cavity of the mouth. If the temp/taste seems high, draw a little faster (has a cooling effect), or alternately, stop the heating and start over. It is best to leave a little bit of lung capacity to draw the remaining vapor fully into the lungs before releasing. A long steady draw is optimal. The steady state method is more vapor efficient and more accurately reflects the design method-of-usage intentions of the Box.
The battery is left in for the duration of the draw, or if taking multiple draws, for as long as the load lasts. You must remember to retract, remove, or invert the battery when you are finished taking draws off the Box. Like with the wind, faster tends to mean cooler. To get higher temperatures in the load, you need to draw very slowly. If drawing directly from the Box (ie, using the Box in the "native mode"), you will also be able to sense the temperature of the vapor stream as well as the taste (this is the recommended practice).
For best taste, it is important to tap or shake (stir) the load frequently.
