I am working on used device works on low not the three higher levels. I drew out circuit so I could see how it works.
The ground goes to three of the four wires to the pad fourth wire is ac positive which goes thru some thing like scr comes in on a1 and goes out on a2 and controlled by gate what I am wondering is if you use jumper wire from a1 to a2 this will bypass the IC and associated parts then positive goes to pad and switch sends grounds to different wire on pad disabling the 2 hour auto off feature what I don'r know is if the ic could control how hot or how much current passes thru? Also the a1 to a2 must pass current or it would not work in low. Some say four wired units send signal back to controller but all four wires on mine are connected with different ohm's between wires.
