Hardie HR6200 Shows “A1” but Station 1 Won’t Run

Controller displays “A1” (station 1 on program A) but no water flows. System sat unused for two years.

Quick Checks

1. Water supply – Ensure main irrigation shut-off is open.
2. Valve wiring – Inspect connections at the valve and controller for corrosion or disconnection.
3. Voltage test – With a multimeter, measure AC voltage between station 1 terminal and common (C) at the controller while station 1 is active. Expect 22–26 VAC.

• No voltage → controller output failure.
• Voltage present but valve doesn’t open → solenoid or valve mechanical issue.

If the controller is dead, replace with a modern unit (Irritrol Rain Dial, Hunter, or Rain Bird).
