Ducted MultiZone Fan Coil

One unit. Up to five independent zones.

The MultiZone is a horizontal concealed fan coil designed to serve up to five independent zones from a single hydronic unit — installed out of sight in the ceiling void, delivering precisely conditioned air through dedicated duct runs to each room.

One unit, five rooms

The MultiZone installs horizontally in the ceiling void — invisible and silent. From a single hydronic connection, it distributes independently controlled conditioned air to up to five separate zones through dedicated duct runs.

Horizontal concealed installation

The unit sits flat in the ceiling void — a mechanical room, above a corridor, or above any accessible ceiling space. No visible equipment anywhere in the living areas.

Up to 5 independent fan modules

Each fan module serves one zone independently. Install 1 to 5 fans depending on the number of zones required — the same chassis accommodates any configuration.

Engineered for whole-home comfort

A single hydronic connection. Up to five zones. One control platform. MultiZone gives mechanical engineers a clean, flexible solution for whole-home zoned air conditioning without multiple units or refrigerant circuits.

True zone independence

Each fan module operates independently — different temperatures, schedules, and modes per zone. Not a damper-based system: each zone has its own dedicated fan.

Single hydronic connection

One supply and one return pipe serves the entire unit — no multiple refrigerant circuits, no complex manifold. Clean, simple mechanical design.

mSense integration

Full integration with Messana’s mSense platform — each zone individually scheduled, monitored, and controlled from a single interface alongside the radiant system.

Why choose MultiZone

When one concealed unit needs to serve up to five independent zones across a whole home, the MultiZone replaces five separate fan coils with a single horizontal unit installed in the ceiling void — one hydronic connection, one control platform, each zone running independently at its own temperature and schedule through dedicated duct runs.

What is Radiant Cooling?

Radiant cooling is an energy-efficient cooling technology that, unlike traditional forced-air systems that cool the air, employs chilled radiant surfaces like ceilings or floors to directly absorb the heat radiated by objects and people within a space. Radiant cooling creates a comfortable, even distribution of coolness, without the need for visible and noisy equipment.

What is a Radiant Ceiling?

A radiant ceiling is a type of heating and cooling hydronic terminal that uses the large unobstructed surface area of the ceiling to transfer thermal energy to or from the objects in a room through thermal radiation. Radiant ceilings can be used as a standalone terminal or in conjunction with other heating and cooling systems to provide an energy-efficient and effective indoor climate solution.
