Richdel 446PR Lightning Damage: Controller Obsolete, Replace with Irritrol Rain Dial

Controller No Longer Manufactured

Richdel 446PR hasn't been made in 10+ years. Any brand controller works as replacement.

Replacement Steps

1. Label each wire as removed from old controller (1, 2, 3… and C/common).
2. Install new controller (Irritrol Rain Dial recommended).
3. Reconnect wires to same terminal numbers.

Why Irritrol Rain Dial

Easy programming, long lifespan, repairable (panel can be swapped), widely available at sprinkler supply stores.
