What it means
The manual says: Heat Pump fault (outdoor unit) - with F-sub-code.
Part involved: outdoor unit.
Likely causes:
- Outdoor unit has reported a fault; the F-sub-code (F0-F27) identifies it; see Logic Air Maintenance Manual troubleshooting and LED sequence on control box interface PCB.
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
- Read sub-code and LED sequence on control box interface PCB; follow Maintenance Manual troubleshooting.
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.
