Problem

The case concerns an NFI QP Grandlux B pergola motorization with a failed control circuit. The installation operates on 230 V outdoors, with a motor, possible LEDs, remote/radio and limit switches. These elements make replacement board compatibility important.

Possible diagnosis

The likely part is the enclosure or control board for the invisible automation of an NFI Grandlux bioclimatic pergola. This identification remains uncertain. An input fuse in the enclosure may also be involved according to the manual, but its value must be read from the existing fuse or inside the enclosure, without extrapolation.

Is repair worthwhile?

Economic viability is uncertain until the correct board or enclosure reference is confirmed and part availability is known. Complete replacement of the pergola is not indicated by the available data.

When to use a professional

Work reserved for a qualified professional. The enclosure is powered by 230 V mains and installed outdoors, with risks of electric shock, short circuit, fire, incorrect wiring or uncontrolled mechanical movement of the pergola slats.

Parts and compatibility

No reliable exact reference for a replacement electronic board is provided. Before purchase, confirm the enclosure’s internal label, the reference printed on the board, the radio/remote generation, the motor/LED connectors and the full QP Grandlux B model with NFI or the installer. A universal board must not be chosen without validation, because limit switches, overcurrent protections, LEDs and radio may be incompatible.
