New controller

Built a single PID with two outputs 220VAC.
I know, I know! That's what the guy wanted, One PID, two SSR's, two mats, one thermocouple, 240VAC. I tried to get him to get another PID, but he didn't want to.powderho wrote:One PID controller to control 2 heat pads.......with one TC? What am I missing here?
If I put one TC on the top cassette piece towards the tip or tail, the middle of the bottom heat pad would be 50-100 degrees different. They are going to have to figure out the perfect spot for that TC and then ramp super slowly. Not ideal.troublemaker wrote:I know, I know!
