Controlled Mechanical Ventilation (CMV) unit with single alternate flow and heat recovery, very low power consumption, for wall-mounted installation (in horizontal).
The system is ideal for installation in single rooms such as living rooms and bedrooms: to improve flow balancing it is normally used in conjunction with another unit, with synchronised flows.

Ideal to remove CO2, indoor pollutants, and prevent problems of condensate and mould, which inevitably damage the structure and compromise the health of the building's occupants.

Characteristics
- Ventilation unit and internal support base made of high-quality ABS, resistant to impact and UV rays, RAL9010
- High-efficiency aerodynamic fan with “winglet” blades, that is, with end fins for utmost silence and best performance
- EC brushless motor with very low power consumption, complete with thermal protection and mounted on ball bearings that guarantee the improved service life of the product, making it also suited to cold climates. Designed for reversible and continuous operation
- Regenerative ceramic core heat exchanger, with high thermal efficiency
- Washable dust filter
- Telescopic pipe that adapts to the thickness of the perimeter wall
- External terminal, complete with insect netting
- Front cover, easy to remove for cleaning without the aid of tools
- Double insulation: no ground connection needed for maximum electrical safety of user
- Totally recyclable plastic
- No condensate drain needed
- Designed and constructed in compliance with the standard EN60335-2-80 (Low Voltage Directive) and the EMC Directive (Electromagnetic Compatibility)

Functions available on models ONE-16 and ONE-41
- Alternate flow with flow reversal approximately every 70 seconds
- Free cooling (Bypass) to avoid heat recovery when not needed
- Incorporated LED to indicate when the “Free cooling” function is active
- Simplified synchronisation of units (for installation in pairs)
- Multi-speed operation (I-II or III): possibility to select the operating speed using the SEL 4xx accessory. The maximum speed (Boost) can also be activated by room sensors such as SEHRxx or SEIRxx

Functions available on models ONE-16S and ONE-41S
- Automatic flow reversal time management (comfort mode) for maximum acoustic and thermal comfort
- Free cooling: possibility for operation in extract mode only or supply mode only to avoid heat recovery when not needed
- Integrated multicoloured LED for visual feedback on unit status
- Simplified synchronisation between multiple units (up to 10), which automatically establishes when said units are connected to each other thanks to a dedicated communication protocol
- Back-up touch button on-board machine
- Incorporated smart humidity control
- Extremely facilitated maintenance, which can be carried out by the end user in total safety thanks to the possibility to remove the internal ventilation unit by means of a magnetic coupling/decoupling system
- Automatic antifreeze protection to prevent the formation of ice on the exchanger
- Using the supplied multifunction remote control, the following functions can be selected: air flow direction (alternate flow, extract only, supply only); free cooling; OFF position; speed (I-II-III-IV-V); comfort or efficiency mode; boost speed; filter reset
