Hardie HHA 11272 Controller Won't Enter Programming Mode

In "Set Programs" mode, display counts down time but won't allow reprogramming. Off/Run mode shows clock fine. Power/battery reset didn't help.

Fix

Power down with battery out for 30+ seconds. Power up without battery. If still faulty, replace controller. Irritrol Rain-Dial recommended. Indoor model uses plug-in transformer; field wires transfer easily (C = common, 1-6 = stations). Check if Hardie faceplate can be swapped into existing case.
