Hardie HHA-11272 Replacement: Rain Dial Panel Swap

Direct Panel Replacement for Hardie HHA-11272

The Hardie HHA-11272 is the "Rain Dial" platform (Hardie was acquired by Irritrol). You can replace just the front panel—no rewiring needed.

How to Swap the Panel

  1. Turn off 120 VAC power.
  2. Unplug the ribbon cable from the back of the panel.
  3. Release plastic hinges; pull panel straight out.
  4. Insert new panel, reconnect ribbon, restore power.
  5. Reprogram schedules (memory is in the panel).

Check the date code in the battery compartment; if <2 years old, warranty may cover a free panel.
