Vapir Air2 help

My wife and I have owned one of these for about 5 years now. We let a friend borrow it for the last 2 years or so because we preferred smoking regularly.

We recently got it back and we were wondering if people had any tips for the best utilization of it? should the temp be set to 392F? How do you increase the timer. it takes about 7 minutes to heat from room temp to 392 which on the default 20 minute timer only leaves a solid 13 minutes for utilization before being interrupted to restart it.

We were finding that we could use the vaporizer for a solid 20 minutes and then just smoke the leftovers... though a bit dryer.

When I used it, I started it off at 325F and after each hit, I would make increments of 5's or 10's until I tasted the herb cooked enough.

I doubt thereâ??s a solution other than reconfiguring the timer that shuts down the device. i would just keep an eye on the light, so once it turns off you can press the heat on and stay around the same temperature you left off.
