Technical features and notable innovations

Eco-friendly refrigerant R-32

Choosing R-32 refrigerant represents a commitment to superior energy performance while reducing environmental impact. Compared to R-410A, it offers better heat transfer capacity and a 68% reduction in global warming potential .

Exceptionally low noise level

The M1WD cassette boasts a noise level between 25 and 32 dB(A) —one of the lowest in its class. This silence is due to the use of a cross-flow fan with curved blades and a 4-speed motor (low, medium, high, turbo) that adapts to each situation.

“Calm Air” air diffusion via micro-perforations

Thanks to “Calm Air” technology, air is diffused through thousands of micro-holes on the front of the unit when the shutters are closed. This creates a gentle and uniform flow , without any noticeable draft, perfect for rest or concentration environments .

Smart connection with built-in Wi-Fi and SmartThings app

The cassette can be controlled remotely via the SmartThings app , compatible with Bixby, Alexa and Google Assistant . This allows for intelligent temperature management , scenario automation (e.g., system activation upon returning home via geolocation), as well as weekly and monthly energy consumption monitoring .

Installation, maintenance and compatibility

Unit designed for quick and efficient installation

At AirGreen , we have already installed this cassette in several properties in Brossard , Saint-Eustache and Saint-Lambert . Its compact design and simplified electrical connection allow our technicians to carry out a discreet and quick installation, without the need for major work.

Standard piping 1/4 - 3/8

Connection to the cassette is made using standard flare fittings , making it easy to integrate into an existing HVAC system or into a new multi-zone configuration with other wall-mounted or ducted units.

Simplified maintenance

A built-in filter captures particles as small as one micron. It is washable or vacuumable , which limits maintenance costs. In addition, a filter maintenance indicator visually signals when cleaning is necessary.

Accessories and controllers available

The LENNOX M1WD cassette is compatible with several optional controllers :

• Rechargeable wireless remote control (via USB-C or solar panel)

• Wired programmable thermostat with touchscreen (VSTAT02P-1)

• 24V thermostat adapter allowing compatibility with standard thermostats

These accessories allow advanced customization of system control, including configuring sleep modes, air purification, and managing supplemental heating.
