Comfort One by VMC Italia: ventilation, air conditioning, and intelligent air management in a single system
Comfort One by VMC Italia is a single system that renews, heats, cools and dehumidifies the air, ensuring well-being and quality throughout the home.
Comfort One is the system developed by VMC Italia that integrates controlled mechanical ventilation, air conditioning, and dehumidification into a single, compact and technologically advanced solution. It's not just a simple VMC unit, but a true multi-service system capable of ensuring clean air, ideal temperatures, and optimized energy consumption. Thanks to its operation based on the use of air as the sole vector, Comfort One overcomes the limitations of traditional systems, improving the quality of life within energy-efficient residential buildings.
An answer to the new needs of modern buildings
New-generation buildings , characterized by high thermal insulation, require systems that combine efficiency and healthiness. Indoor air tends to stagnate, increasing the risks associated with humidity, condensation, and indoor pollutants. Comfort One was created to meet these challenges: the system ensures continuous air exchange and filtration , with high-efficiency filters capable of retaining fine particulates and allergens, maintaining constant humidity levels and improving air quality in every season.
The heart of the system is the LET I units—available in various versions and configurations—which integrate a high-efficiency heat recovery unit (up to 90%) and a hydronic coil connected to an external heat pump. This way, Comfort One combines ventilation, dehumidification, cooling, and heating in a single system, reducing installation costs and space requirements.
Intelligent thermoregulation with Thermolocal
One of Comfort One's strengths is the Thermolocal system, an exclusive device developed to precisely manage air distribution in different rooms . Thanks to an internal algorithm, Thermolocal modulates the air flow rate for each room based on the customer's setpoint and the fan's operating curve. This approach allows for precise and personalized temperature control, with the advantage of ensuring constant comfort even in multi-story buildings or with complex air conditioning needs.
In addition to improving living comfort , Thermolocal significantly reduces electricity consumption by optimizing the use of the system only where needed, and reduces the unit's noise level thanks to flow rate modulation. This system not only offers advanced control of internal climate conditions but also significantly optimizes management and maintenance costs.

Advanced electronic control and remote management
Comfort One is managed by advanced electronics , easily operated via both the VMCDISPLAY touch screen panel and the dedicated Vmc Controller app , which allows for remote control. Users can set fan speeds, summer/winter modes, setpoints, and time slots, customizing operation to suit their daily habits.
Thanks to connectivity, Comfort One not only guarantees maximum control for the end user, but also offers the option of remote monitoring by VMC Italia technicians. In the event of malfunctions or the need for assistance, the unit can be remotely controlled for quick and reliable diagnosis, reducing intervention times and increasing overall system reliability.

Flexibility of installation and contexts of use
The Comfort One system was designed to adapt to various building types and installation methods. The vertical and horizontal versions of the LET I 15/60 and LET I 25/80 units allow for both floor and suspended ceiling installation, taking up minimal space and facilitating architectural integration. Thanks to the option of installing suspended ceilings or plasterboard walls, the system is completely invisible, preserving the aesthetics of the interior spaces.
Its performance, with air flow rates of up to 800 m³/h and heating and cooling capacities that cover a wide range of needs, makes Comfort One the ideal solution for single- and multi-family homes, as well as for small residential complexes with semi-centralized systems. The option to integrate accessories such as high-efficiency electrostatic filters or ionization systems enhances the system's air quality performance, fully meeting end users' comfort and health needs.
