Hardie System "ERROR 1": Zone 1 Solenoid or Wire Short

Hardie controller showing "ERROR 1" = short circuit on zone 1 (solenoid or wiring).

Reset & Test

1. Remove battery, disconnect power 30 sec, restore.
2. Run zone 1 manually. "ERROR 1" returns? → Fault confirmed.

Fix

1. Replace zone 1 solenoid (unscrew old, screw new).
2. If error persists → trace zone 1 wire for nick/short to ground/common.

Solenoid first. Wire second. Controller last (rare).
