Hardie Total Control 15-Station: "Short" Error Message

Hardie Total Control 15-station outdoor timer displays "Short" across screen. System inoperable.

"Short" = Electrical Short in Field Wiring

Not the controller itself. Most likely:

• Bad wire connection at a valve (corroded, loose, water in wire nut).
• Bad connection at controller terminal strip.
• Failed solenoid (short internally).

Fix Procedure

1. Inspect all valve wire connections at controller—replace with waterproof wire nuts.
2. Inspect connections at each valve—same.
3. Disconnect power and battery for 2 minutes.
4. Reconnect, reprogram, test.

If "Short" persists, disconnect field wires one zone at a time to isolate the faulty circuit.
