Hi ZGR! I'd be glad to help, another controller that has one more PGM is the ESP4ME3 controller (A-B-C-D). If you need more PGMs, then another option will be the ESPLXME2 controller which can run up to 40 PGMs. Here is a link for more information: www.rainbird.com/products/esp-lxme2-esp-lxme2-pro-modular-controllers, hopefully, this helps!
