ALIZÉ HYGRO and ALIZÉ VISION vents in ventilation systems are covered by Technical Appraisal No.14.5/17-2269 "VMC hygroréglable ALIZE 2018 for collective housing" and No 14.5/17-2268 "VMC hygroréglable ALIZE 2018 for individual housing”.


Combined bathrooms & WC: the ALIZÉ HYGRO VISION vent modulates airflow in line with the room’s ambient relative humidity and provides a 30-minute timed boost triggered by presence detection.

This vent comes in 4 models:
• ALIZÉ HYGRO TEMPO cordon (HTC) : controlled by cordon

• ALIZÉ HYGRO VISION 230 V (HVE) : controlled by presence detection, 230 VAC power supply
• ALIZÉ HYGRO VISION 12V (HVBT) : controlled by presence detection, 12 VAC power supply

• ALIZÉ HYGRO VISION battery (HVP) : controlled by presence detection, 2 x 1.5V battery operated

In addition to the general installation guidelines (See general information tab) :

Battery operation: Check the batteries yearly. When the vent fails to open properly (no sound from the motor), the batteries need changing. 

230VAC operation: the power supply to the vent must be via a recessed 2-wire cable (2 x 1.5 mm²) leading to the back of the support plate (diagram opposite).

Class 2 electrical Appliance.

12VAC operation: the power supply to the vent must be via a recessed 2-wire cable (2 x 1.5 mm²) leading to the back of the support plate (diagram opposite). 

Class 2 electrical appliance.

In the wall-mounted position, the detection lens must be at the bottom of the vent. In the ceiling-mounted position, the lens must point toward the room centre.

We recommend screwing the vent support plate to the wall or ceiling through the 3 holes provided for this purpose on the plate.
