Hardie RainDial: All Zones Flash "Off" and Won't Run

After 1–2 years of disuse, a Hardie RainDial controller flashes "Off" on all zones in manual mode. Power and battery reset didn't help.

Solution

The controller likely lost its programming. Stations must have run times assigned to operate. Reprogram the controller using the manual, available at Irritrol Manuals. Ensure each zone has a start time, run time, and watering days set.
