FAQ

Frequently Asked Questions — Wolf REMOTE COMM ERR

• Can I operate my Wolf range hood manually if the wall control has failed?
  On some Wolf hood configurations with a dedicated wall control, the hood can only be operated through that control — there are no backup controls on the hood canopy. On other configurations, manual controls remain on the canopy liner. Consult your Wolf hood installation documentation to determine whether manual backup controls are available on your specific model.
