Richdel 446PRi: Can Only Water Every 2-4 Days, Not Specific Days

Richdel 446PRi hybrid controller: can't set specific days (Wed/Sat only). Options: every 4 days, every 3 days, every 2 days, or daily.

Controller Limitation

This model does not support day-of-week programming. It only offers interval scheduling.

Best Compromise

• Every 3 days → Waters ~2.3 times/week (close to 2x)
• Every 4 days → Waters ~1.75 times/week
