Kiln control retrofit

Original control was two switches with high low off for each element. No temperature control at all. It required close watching.

  New control kit has two SSR's a type K thermocouple and a ramp and step control. From Amazon https://www.amazon.com/gp/product/B07YN5YLS6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Mostly installed, I put the SSR's low to keep them out of the heat and made a heat shield for the controller.

Thermocouple installed in the upper peep hole. Controller pulses SSR's to control heat input.
