Bioclimatic pergola motor and electronics: causes of faults and voltage regulator

Bioclimatic pergola motor and electronics: causes of faults and voltage regulator

01.11.2026 6 min read SkyArt Group

The main cause of electronic faults in a bioclimatic pergola is unstable voltage, so a voltage regulator is recommended. After checking the remote, obstructions and cleanliness, call service rather than dismantling the system yourself.

How the system runs

The louvres of a bioclimatic pergola move by motor and belt. The piston model uses a mainboard and control card to tilt the louvres in place and, if wanted, run the rear retracting motor; the scissor model has no card, the rear motor pulls the roof front to back and the system is simpler. Control is by remote, with an optional phone app and optional rain, sun and wind sensors. See our Albert Genau models post; SkyArt Group is an Albert Genau authorised manufacturing dealer.

Why a voltage regulator

Electronic cards can be damaged when mains voltage fluctuates. A regulator protects them. Its cost is small compared with the system; we give details at the survey.

What not to do

  • Do not open the motor, card or belt yourself; the warranty may be void.
  • Keep louvres closed in rain and wind.
  • Motor and mechanics carry a 2-year warranty; afterwards maintenance is paid, and regular maintenance extends the warranty.

See the maintenance guide or request service.

Frequently asked questions

Why does a bioclimatic pergola fail?

Most often unstable voltage damaging the cards. Obstructions, dirt and missed maintenance also hinder movement.

Is a voltage regulator necessary?

It is recommended; it protects the electronic cards from mains fluctuations.

Does the scissor system have a card?

No. The rear motor pulls the roof, so it is simpler with less electronics.

Can I open the system myself when it fails?

We advise against it; the warranty may be void. Call service.
