I start vaping it and when it reaches the temp it gives me the message and stops firing. I'm using dual ss316L round wire and contact coil. This happens in temp control and in replay mode, what I've also noticed is that when that happens I change from one profile to another i.e. ss316l to replay and vice versa, and it starts firing again. Then, after some time it happens again. Not home right now, as getting home will send a picture of the mod monitor on escribe.
