Resetting a Rain Dial Hardie Controller (Model P/NHHA11272)

If your Rain Dial Hardie controller (manufactured 6/91, code P/NHHA11272) is running stations simultaneously or out of sequence, a full reset often resolves the issue. This controller defaults to Program A with 10 minutes per zone, daily at 7:00 AM after reset.

Reset Procedure

1. Remove the 9-volt backup battery.
2. Disconnect AC power (unplug or turn off breaker) for 30 seconds.
3. Reapply power, then reinstall the battery.

The controller will now run all 12 stations on Program A for 10 minutes each, every day at 7:00 AM. You can then reprogram schedules as needed.
