Irritrol MC‑30 Plus Won’t Run Automatically – Programming or Hardware Fault?

The controller runs programs manually but not in auto‑run mode. Day/time are correct, no overlapping programs.

Clear all programs and reprogram from scratch using the manual (irritrol.com/manuals/manual_mcplusb.pdf).
If the problem persists, the microprocessor may be failing.

Consider the Hunter Pro‑C, which has proven highly reliable in the field.
