A complete listing of the controller operating menu is located on an 11’ x 17’ fold out in the Wiring and
Diagram section in the back of the manual (see last page in book). It is designed to be folded out so you
can continuously view it as you are learning how to navigate the MP-4000 Controller Menu. It is
