Aqua-Hot error code SYSTEM VOLTAGE
Supply voltage out of range - the Reporter triggers a System Voltage fault when it receives below 11.8V DC (it is designed to operate between 11V and 16V DC); below 11.2V DC for 30 seconds it discontinues operation of the heating system.
What to check, and in what order, is in the app. The flow Aqua-Hot Reporter — Fault Screen Triage walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
