I've really only used this twice for a cook, and was more satisfied this second time.

Different applications may need different modes, Say PID,PI, PD, or P only.
I have extensive test on rice cooker when doing sous vide on controller FOX, 80-260VAC, 15A.
PID math. is same in FoX and Wolf Tiger Lion and DOG
Followings are result on rice cooker
