1. Product Overview
The AERAULIQA QX80HT is a centrifugal extractor fan with a 73.5mm diameter, designed for efficient ventilation in bathrooms, toilets, and small to medium-sized rooms. It effectively extracts stale air and can overcome resistance from long ducts. This unit is suitable for both wall and ceiling installation, including recessed plasterboard applications. It features a minimalist design front cover that is easily removable for cleaning without the need for tools. An aerodynamic grille minimizes air turbulence for enhanced acoustic comfort. A PP filter protects the fan and motor, and is also easily removable for maintenance. A butterfly backdraft damper accessory is supplied as standard. The QX80HT is IPX4 rated, features double insulation, and is TÜV Rheinland certified. Proudly Made in Italy.
Key features include a humidity sensor that automatically activates or deactivates the unit when the relative humidity exceeds or falls below a user-set level (adjustable between 50% and 95%). It also incorporates a timer function that delays the unit's shutdown for a pre-set duration (adjustable between 1 and 25 minutes).

4.3. Electrical Connection
The QX80HT operates on 220-240V 50/60Hz. Ensure all electrical connections are made by a qualified professional and comply with local electrical codes.
The unit features a single-phase 2-speed motor with long-life ball bearings and built-in thermal protection.
5. Operation
5.1. Humidity Sensor Settings
The integrated humidity sensor activates or deactivates the fan based on the ambient relative humidity. The humidity threshold is adjustable between 50% and 95%. Use a small screwdriver to adjust the potentiometer labeled for humidity settings on the control board (refer to the internal diagram in the installation manual for exact location).
5.2. Timer Settings
The timer function allows the fan to continue operating for a pre-set period after the humidity level drops below the threshold or after manual activation. The delay time is adjustable between 1 and 25 minutes. Adjust the potentiometer labeled for timer settings on the control board (refer to the internal diagram in the installation manual for exact location).
5.3. Speed Control
The fan features a two-speed motor. The speed setting can typically be configured during installation or via internal jumpers/switches on the control board, depending on the desired airflow and noise level. Consult the detailed wiring diagrams in the full manual for specific speed selection instructions.

6. Maintenance
6.1. Cleaning the Front Cover and Filter
The minimalist design front cover is easily removable for cleaning. Gently detach the cover from the main unit. The internal PP filter, which protects the fan and motor, can then be accessed and removed for cleaning. Wash the filter with mild soap and water, rinse thoroughly, and allow it to dry completely before reinserting. Reattach the front cover securely.
Frequency: Clean the filter and front cover regularly, depending on the operating environment and usage, to maintain optimal performance and airflow.
6.2. General Cleaning
Wipe the exterior of the fan with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the ABS material. Ensure no water enters the electrical components.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power supply; incorrect wiring; humidity sensor setting too high; timer not activated. | Check power connection; verify wiring with a qualified electrician; adjust humidity sensor to a lower percentage; check timer settings. |
| Reduced airflow. | Clogged filter; blocked ductwork; fan operating at lower speed setting. | Clean the PP filter; check and clear any obstructions in the ductwork; verify fan speed setting. |
| Excessive noise. | Loose mounting; foreign object in fan blades; worn bearings. | Ensure fan is securely mounted; inspect for and remove any foreign objects; if bearings are worn, contact customer support for service. |
| Humidity sensor not responding. | Sensor malfunction; incorrect humidity threshold setting. | Adjust humidity threshold setting; if problem persists, contact customer support. |
