Vapor.wise
I've been playing around with it last night and actually vaped a decent bowl at 12. I have to take quick sharper draws that last about 1 second. Doing this I'm able to get about 4-6 hits. If I draw slower it turns very dark brown almost popcorn like in taste.
If at 9 o'clock it is too hot, no matter how fast you draw, there is a strong probability there is something wrong with the heating element. Differences between the relative position of the knob and its temperature are know in this model, but they are minor differences, not like it seems in your case that it is "combustion hot" at 9.
I would suggest you take fast draws, but you can pull longer than 1sec, and don't do multiple 1sec draws with no intervals.. that will make the temp to rise quickly.
Usually the slower the draw the higher the temps, BUT if you do quick micro hits, like when you want to re-light a cigarete, it will rise the temp as well.
The only way to draw and lower the temps is one continuous quick draw, not super quick like when you clear a bong, but quick.
