I have the exact kiln...I’m use to my old kiln which had three dials high med and low...I’m not sure how to use these dials...do I turn them clock wise...? Will they switch on their own...? How do I do a bisque cone 04 and what do I do with the dials for a cone 6 glaze...? Also at the bottom what’s that switch. For...thx in advance for any advice
