What it means
The manual says: Inverter error.
Part involved: outdoor inverter PCB.
Likely causes:
- External cause; power supply wiring to main PCB disconnected/open; inverter PCB failure; main PCB failure.
Is it safe?
| Does the heat pump stop? | Yes |
|---|---|
| Engineer needed? | Yes |
The heat pump stops until the fault clears or is reset.
What you can check
- Note the code or fault message shown on the controller/Halo and when it appeared; check the heat pump's isolator and consumer-unit breaker are on. If the fault clears after the installer-approved restart via the controller and does not return, note it for the next service; if it returns, call an engineer.
What the engineer will check
- Power cycle; check connectors and cables; replace inverter PCB then main PCB.
Who to ask for: Heat pump engineer; casing removal only by persons competent with R32 (A2L); refrigerant-circuit work requires Cat I/II F-gas certification (I&M p.75 warning).
Certification: F-gas Cat I/II for refrigerant work; electrical work by competent person.
