• General characteristics

    µAria is the ready-to-use solution for managing residential air handling units with heat recovery.

    µAria is a parametric controller, designed to reduce time and costs from the design phase to the start-up phase. Its flexibility allows it to handle the entry level HRV compact machine range up to about 1000 m3/h.
    CAREL's knowledge in the field of air handling units ensures intelligent control logic, ensuring optimal operation of all devices. 
    Multiple types of probes and sensors (temperature, humidity, CO2, VOC, etc.) can be managed, which measure the desired values and use them for the defined adjustment modes. This ensures a high level of comfort in the rooms served by the unit by controlling air quality and air exchange, while optimising energy performance.

    µAria offers an advanced user experience thanks to its standard Bluetooth and NFC wireless connectivity, in combination with the APPLICA App. 
    APPLICA, which can be downloaded free of charge to smartphones from Google Play for Android or App store for iOs, makes it possible to fully configure the unit in a few simple steps thanks to the pre-loaded synoptics and configurations. 
    Combined with the th-Tune terminal, the user can easily adjust temperature and humidity to achieve the desired environmental conditions.
