Nibe F1155 - Troubleshooting

Caution
Selecting "aid mode” is not the same as correcting the problem that
caused the alarm. The status lamp will therefore continue to be red.
If the alarm does not reset, contact your installer for suitable remedial ac-
tion.
NOTE
Always give the product's serial number (14 digits) when reporting a
fault.
