Rain Jet Timer "Bad 4" Error: Capped Zone Fix

6-zone Rain Jet timer (4 stations) shows "Bad 4". Zone 4 capped off for deck repair. Wants remaining 3 zones to run.

Fix

  1. Disconnect zone 4 wires from controller terminals.
  2. Full reset: remove AC power and battery backup for 2–3 minutes.
  3. Reconnect power, reprogram controller.

The "Bad 4" indicates an open circuit on station 4. Removing the wires clears the fault.
