[Temperature Control]

Hi All,

I want to start by saying thanks to everyone who helped with my motor control and speed control program, I took sometime sat down and it works flawlessly. I added in my thermocouples to tell me temperature and they work perfect, however I came up with the idea now to reach a max temperature of 600 degrees then turn off my heat source until it drops below 400 degrees then start it up again, I had an idea of using a PID but I feel there has to be a simpler and easier way. Thanks in advance for you help.
