Glad this is working for you. Does your control box have an ON/OFF switch? or a switch for the element? Or do you not plug it in until you're ready to heat and rely on the PID buttons for controlling the temp and/or the power to the element? I looked at the "Instructables" site. The hand-drawn schematic on that site appeared to show an element switch, but I could not see it on the photos of the controller box. Thanks.
