I've been vaping on my DNA40 chipped Sagittarius mod for a while now. Recently I have noticed I have no response on the display screen for temperature when in Temp Control Mode. It does show temp set at but blanks out when I hit the fire button. It seem to be reverting to standard Watt control. I'm using a NI200 .12 ohm coil. I don't know how long its been going on Just noticed it this morning. Two attys with similar coils produce the same results. Has temp control failed?
