Control all year round
The Flexa 25 system for underfloor heating and cooling can be used with a radiant heating system and cooling elements. Heating and cooling using radiant elements is more comfortable than any other method, mainly because of the direct transmission of the temperature to the user.

Zone control
Two-way communication with the indoor AC unit adapts production to the real needs of the installation. Zoned temperature regulation, which integrates the control and combined operation of air and water conditioning technologies, optimizes unit performance, providing maximum comfort and average energy savings of up to 30%.

Connectivity
Flexa 25 offers centralized remote control through the Airzone Cloud app. Compatible with the Webserver HUB, it facilitates the integration of HVAC installations with home automation and building management systems, ensuring the optimal and unified management of energy consumption.

Radiator control
Flexa 25 incorporates the management of radiators in conjunction with the ducted HVAC system. Thanks to the combined control and use of our algorithms, heated and cooled spaces reach the comfort temperature more quickly, reducing energy consumption.

HVAC control
Flexa 25 goes beyond just managing HVAC—it also monitors and optimizes air quality. With AirQ Sensor, it detects the concentration of CO₂, TVOCs, and harmful particles, automatically activating air purification through AirQ Box or the ventilation system to ensure a cleaner, healthier indoor environment.
