Follow these steps to configure your watering schedule using the central dial and interface buttons (Manual On, Advance, and Arrow keys): : Turn the dial to Time & Day .
If you measure 24‑30 VAC at the station terminal but the valve does not open, the issue is often rather than voltage. Solution: Check resistance (ohms) of the solenoid (typically 20‑60 ohms) and verify the wire run is not too long or the connections are not corroded. Try moving the valve wire to a different station terminal to isolate the problem. A solenoid that works with a 9‑volt battery may still fail with the timer if the current is insufficient due to high resistance in the wiring or poor connections.
