Thank you for your help. I did a few simple changes to the setup from:
viewtopic.php?f=8&t=6565, that I found useful: That way Temperature can be handle directly in Settings.
I use T0 to define the 16 tools(colors) in Temperature Tab in the FFF Settings, and I use T1 to set the temperature of the hotend.
