What it means
The manual says: Outdoor unit main PCB error / communication error in outdoor unit.
Part involved: outdoor main PCB (EEPROM).
Likely causes:
- 1. External cause (noise, momentary open, voltage drop) 2. Main PCB failure (EEPROM access failed).
Is it safe?
| Does the heat pump stop? | Not stated |
|---|---|
| Engineer needed? | Yes |
The manual does not say whether the heat pump stops.
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. Check whether lights or other appliances are also affected (possible supply problem) and whether any breaker/RCD has tripped - do not reset repeatedly.
What the engineer will check
- Reset power; check for voltage drops/momentary open/earthing and nearby cables; replace 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.
