Artisan PID turns heater back on during cool down
BadHabitRoasters	#1 Posted on 07/03/2023 12:08 PM
Newbie Posts: 46 Joined: March 18, 2013	Finally got my DIY fluid bed running using a background profile and Artisan PID. I'm wondering what's making my PID reinitialize after Drop. When I click the Drop button, it turns the heater off and will cool the beans for 2 - 5 minutes and then the heat comes back on. Do I have some box checked that needs to be unchecked or it as simple as I need to turn off Control when the roast is done with need for heat?

But this scenario assumption collides with your following background profile statement... which is not Manual mode. So we need more details about your setup. renatoa attached the following image:
