Hardie Total Control Error Code #1: Short on Valve 1 Circuit

Error Code #1 on a Hardie Total Control 15-station controller means: Valve 1 circuit shorted the internal breaker when it tried to activate.

Causes

• Shorted solenoid on valve 1
• Damaged wire (nicked, crushed, water in splice)
• Wire crossed with another zone or common

Diagnosis

1. Disconnect wire from controller terminal 1.
2. Run program — if error clears, fault is in field.
3. Measure solenoid resistance (ohms): should be 20–60 Ω.
4. Inspect wire run for damage.

Fix

Replace solenoid or repair wire. Reset controller after fix.
