269 on a NIBE heat pump: Non-compatible outd air heat pump: Heat pump and indoor module are incompatible [other NIBE documents: Heat pump and indoor module do not function together due to technical parameters / Outdoor unit connected is not compatible, or DIP switch settings faulty]
Short answer
On a NIBE heat pump, 269 means: Non-compatible outd air heat pump: Heat pump and indoor module are incompatible [other NIBE documents: Heat pump and indoor module do not function together due to technical parameters / Outdoor unit connected is not compatible, or DIP switch settings faulty]. The heat pump keeps running with some functions stopped. An engineer is needed to fix the cause.

What it means
The manual says: Non-compatible outd air heat pump: Heat pump and indoor module are incompatible [other NIBE documents: Heat pump and indoor module do not function together due to technical parameters / Outdoor unit connected is not compatible, or DIP switch settings faulty].
Part involved: PCB / software configuration.
When it shows: Heat pump and indoor module are incompatible; Heat pump and indoor module do not function together due to technical parameters; Outdoor unit connected is not compatible, or DIP switch settings faulty.
Likely causes:
- S2060: Heat pump and indoor module not compatible | F2050: Outdoor module and indoor module are not compatible.
Is it safe?
| Does the heat pump stop? | Partly |
|---|---|
| Engineer needed? | Yes |
The heat pump keeps running with some functions stopped.
Resetting itself: no/unknown - Hot water blocked; unit cannot be restarted after power off.
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. Note the alarm and contact your installer; no homeowner action beyond resetting.
What the engineer will check
- Check serial number/software versions, PCB type and DIP switch settings; update software or replace PCB as required. NIBE lists: Heat pump and indoor module not compatible; Outdoor module and indoor module are not compatible.
Who to ask for: NIBE-trained heat pump installer (NIBE PRO / VIP).
Certification: None specific beyond competent heat pump installer; electrical work to BS 7671.
