I understand all of that and I did not go through 42 pages to see that, my apologies. I have stated what I have done to make it work. I have not been told how to wire in a relay to FOR and DCM to get the relay to work so I had to figure it out myself. I also KNOW that the PID settings are common, I just made sure to post them for PC control in case others needed it. I would gladly wire in a relay. I am just trying to work with what I have as I do not have $$ to buy more things right now. I have a 12v relay in hand and if I can use that, fine. Otherwise, I will have to make due with what I have for now.
