Sorry for taking so long to respond....I just now came back to this thread. I have a "manual" for mine, but it was either written by a 1st grader, or they left a bunch of pages out...it has no wiring diagrams, nor even a diagram that labels each of the terminals. After trying everything I could to get the information, including emails and phone calls with no responses, I gave up on anything with "Watlow" on it. My impression of that company is that if you're not the purchasing agent for a major corp. or have a maintenance contract with them, they could care less about you. My recommendation is to either trash or give that one away, and purchase one of the controllers from the link(s) in my last post.
