What it means
The manual says: Refrigerant sensor has to be replaced soon: Refrigerant sensor BQ10 must be replaced soon; if not replaced within the stated days operation will be limited.
Part involved: refrigerant (leak) sensor BQ10.
When it shows: Refrigerant sensor BQ10 must be replaced soon; if not replaced within the stated days operation will be limited.
Likely causes:
- S2060: Warning appears monthly from 14.5 years until 15 years.
Is it safe?
| Does the heat pump stop? | Not stated |
|---|---|
| Severity | Warning |
The manual does not say whether the heat pump stops.
Resetting itself: yes - information messages reset automatically when the cause is rectified.
Manual reset: Reset from the controller alarm menu ('reset alarm' / 'Reset alarm and try again'); alarm recurs if the cause remains.
What you can check
- Read the alarm text and the 'info/action' help on the controller display (VVM/SMO or S-series smartguide). NIBE's manuals let the homeowner select 'reset alarm' ('Reset alarm and try again' on S-series); if the lamp returns to normal the alarm has cleared. If it comes back, do not keep resetting: select 'aid mode' ('Auxiliary operation' on S-series) if offered, so any electric additional heat keeps heat/hot water going, and contact your installer.
What the engineer will check
- Check refrigerant sensor BQ10 and its cable; replace sensor at end of life (15 years) per NIBE instructions. Treat as R290 safety function. NIBE lists: Warning appears monthly from 14.5 years until 15 years.
Who to ask for: NIBE-trained heat pump engineer competent with R290 (A3) refrigerant systems.
Certification: Competence for flammable (A3, R290) refrigerant systems; F-gas certification if the refrigerant circuit is opened.
