other side screws go to pid You need to run one side of the 220 into the ssr (switch) the other screw goes to the element and the other side of the 220 input goes to the other side of the element. This is dangerous and a switch should be put inline with the element side of the 220 ( as it is always on 110v ) input or use two ssr s. You really need to pm dward51. Hes the man here. I know he will get you going. I don't explain well.
