Hardie Slim Line Controller Dim/Broken Display—Replacement Needed

15-year-old Hardie Slim Line controller has very dim, broken LCD readout. Hard to read.

Reality

LCD crystal degradation is irreversible. Hardie was acquired by Irritrol—no parts available.

Irritrol Rain Dial controller — direct modern equivalent, easy programming, long-lasting. Same wiring configuration for simple swap.

Don't waste time on repair—technology is obsolete.
