HRV Valsir Ariosa HV SENSIBLE LITE

Description

Valsir ARIOSA HV Sensible LITE is a simplified version of the ARIOSA HV Sensible central heat recovery ventilation unit for residential buildings. It uses the same heat exchanger, casing, EC motors and airflow performance as the full Sensible version, but with a reduced control and sensor package. This makes the LITE version an economical choice for projects where reliable, continuous ventilation is required without advanced automation or connectivity.

The unit can be installed horizontally in a false ceiling or vertically on the wall and is available in three airflow sizes (170, 250 and 330 m³/h), covering living spaces up to approximately 185 m² depending on the chosen model. The sensible counterflow heat exchanger and EC motors ensure stable air exchange and energy saving operation, while the simplified analog control panel allows basic configuration and commissioning on site.

Energy efficiency

The sensible counterflow heat exchanger recovers dry heat from the extracted air and transfers it to the incoming fresh air, reducing heating demand during the colder season. As the LITE version shares the same mechanical components as the full Sensible range, it maintains the same high heat recovery efficiency values and low specific power consumption, offering long term energy savings in residential applications.

Indoor air quality

ARIOSA HV Sensible LITE provides constant filtered airflow through both supply and extract ducts, helping to reduce CO₂ concentration, excess humidity and indoor pollutants. The unit uses the same filter layout and airflow paths as the full Sensible model, ensuring stable and balanced ventilation throughout the dwelling. Regular filter inspection and replacement keep the system performance and indoor air quality at the desired level.

Controls and automation

The LITE version is equipped with two onboard probes for basic monitoring and an analog control panel without an LCD display. The panel provides physical buttons for fundamental machine setup and operating mode selection but does not support advanced menus, time scheduling or detailed status visualisation. In the LITE version there is no Wi-Fi connectivity and no Modbus interface, so the unit cannot be integrated with home automation systems or controlled via the Valsir App. This configuration is ideal where simple stand alone operation is sufficient and budget is a priority.
