Hardie Rain Dial (~15 Years) Only Runs Zone A – Controller Failed

15-year-old Hardie Rain Dial runs only Zone A regardless of programming, in all modes. Reset and reprogram didn't help.

Verdict

Controller microprocessor failed. Hardie bought by Irritrol; Rain Dial series continues.

Replace panel only (~$110), not entire enclosure. Easy swap.
